ous line voltages. When servicing drives and electronic controllers, there may
be exposed components with housing or protrusions at or above line potential.
Extreme care should be taken to protect against shock.
Stand on an insulating pad and make it a habit to use only one hand when
checking components. Always work with another person in case an emer-
gency occurs. Disconnect power before checking controllers or performing
maintenance. Be sure equipment is properly grounded. Wear safety glasses
whenever working on electronic controllers or rotating machinery.

!Caution Remarks for using ground fault interrupter breakers in the main power supply:
Adjustable frequency inverter with integrated CE-filters and shielded
(screened) motor cables have a higher leakage current toward earth GND.
Especially at the moment of switching ON this can cause an inadvertent trip of
ground fault interrupters. Because of the rectifier on the input side of the
inverter there is the possibility to stall the switch-off function through small
amounts of DC current. ............................................................................... 50
Please observe the following:
• Use only short time-invariant and pulse current-sensitive ground fault
interrupters with higher trigger current.
• Other components should be secured with separate ground fault inter-
rupters.
• Ground fault interrupters in the power input wiring of an inverter are not an
absolute protection against electric shock. ........................................... 50
!Caution Be sure to install a fuse in each phase of the main power supply to the
inverter. Otherwise, there is the danger of fire. ........................................... 50
!Caution For motor leads, ground fault interrupter breakers and electromagnetic con-
tactors, be sure to size these components properly (each must have the
capacity for rated current and voltage). Otherwise, there is the danger of fire.

General Warnings and Cautions
!WARNING Never modify the unit. Otherwise, there is a danger of electric shock and/or
injury.
!Caution Withstand voltage test and insulation resistance tests (HIPOT) are executed
before the units are shipped, so there is no need to conduct these tests before
operation.
!Caution Do not attach or remove wiring or connectors when power is applied. Also, do
not check signals during operation.
!Caution Be sure to connect the grounding terminal to earth ground.
!Caution When inspecting the unit, be sure to wait ten minutes after turning OFF the
power supply before opening the cover.
General Warnings and Cautions
4
!Caution Do not stop operation by switching OFF electromagnetic contactors on the
primary or secondary side of the inverter.
When there has been a sudden power failure while an operation instruction is
active, then the unit may restart operation automatically after the power failure
has ended. If there is a possibility that such an occurrence may harm humans,
then install an electromagnetic contactor (Mgo) on the power supply side, so
that the circuit does not allow automatic restarting after the power supply
recovers. If the optional remote operator is used and the retry function has
been selected, this will also cause automatic restarting when a Run command
is active. So, please be careful.
!Caution Do not insert leading power factor capacitors or surge absorbers between the
output terminals of the inverter and motor.

!Caution MOTOR TERMINAL SURGE VOLTAGE SUPPRESSION FILTER
(For the 400 V CLASS)
In a system using an inverter with the voltage control PWM system, a voltage
surge caused by the cable constants such as the cable length (especially
when the distance between the motor and the inverter is 10m or more) and
cabling method may occur at the motor terminals. A dedicated filter of the
400 V class for suppressing this voltage surge is available. Be sure to install a
filter in this situation.

!Caution EFFECTS OF POWER DISTRIBUTION SYSTEM ON INVERTER
In the case below involving a general-purpose inverter, a large peak current
can flow on the power supply side, sometimes destroying the converter mod-
ule:
1.
The unbalance factor of the power supply is 3% or higher.
2.
the power supply capacity is at least 10 times greater than the inverter ca-
pacity (or the power supply capacity is 500 kVA or more).
3.
Abrupt power supply changes are expected, due to conditions such as:
a)
Several inverters are interconnected with a short bus.
b)
A thyristor converter and an inverter are interconnected with a short
bus.
c)
An installed phase advance capacitor opens and closes.
Where these conditions exist or when the connected equipment must be
highly reliable, you MUST install an input side AC-reactor of 3% (at a voltage
drop at rated current) with respect to the supply voltage on the power supply
side. Also, where the effects of an indirect lightening strike are possible, install
a lightening conductor.
!Caution SUPPRESSION FOR NOISE INTERFERENCE FROM INVERTER
The inverter uses many semiconductor switching elements such as transis-
tors and IGBTs. Thus, a radio receiver or measuring instrument located near
the inverter is susceptible to noise interference.
To protect the instruments from erroneous operation due to noise interfer-
ence, they should be used well away from the inverter. It is also effective to
shield the whole inverter structure.
The addition of an EMI filter on the input side of the inverter also reduces the
effect of noise from the commercial power line on external devices.
Note that the external dispersion of noise from the power line can be mini-
mized by connecting an EMI filter on the primary side of the inverter.
!Caution When the EEPROM error E08 occurs, be sure to confirm the setting values
again.

Model-specific tables for 200 V and 400 V class inverters
The following tables are specific to MX2 inverters for the 200 V and 400 V
class model groups. Note that General Specifications on page 7 in this chap-
ter apply to both voltage class groups. Footnotes for all specification tables fol-
low the table below.
Footnotes for the preceding table and the tables that follow:
Note 1
The protection method conforms to JEM 1030.
Note 2
The applicable motor refers to a standard 3-phase motor (4p). When using
other motors, care must be taken to prevent the rated motor current (50/
60 Hz) from exceeding the rated output current of the inverter.
Note 3
The output voltage decreases as the main supply voltage decreases (except
when using the AVR function). In any case, the output voltage cannot exceed
the input power supply voltage.
Note 4
To operate the motor beyond 50/60 Hz, consult the motor manufacturer for the
maximum allowable rotation speed.
Note 5
For achieving approved input voltage rating categories:
• 460 to 480 VAC - Over-voltage category 2
• 380 to 460 VAC - Over-voltage category 3
To meet the Over-voltage category 3, insert an EN or IEC standard compliant
isolation transformer that is earth grounded and star connected (for Low
Voltage Directive).
Note 6
At the rated voltage when using a standard 3-phase, 4-pole motor.

Note 7
The braking torque via capacitive feedback is the average deceleration torque
at the shortest deceleration (stopping from 50/60 Hz as indicated). It is not
continuous regenerative braking torque. The average deceleration torque var-
ies with motor loss. This value decreases when operating beyond 50 Hz. If a
large regenerative torque is required, the optional regenerative braking unit
and a resistor should be used.
Note 8
The frequency command is the maximum frequency at 9.8 V for input voltage
0 to 10 VDC, or at 19.6 mA for input current 4 to 20 mA. If this characteristic is
not satisfactory for your application, contact your Omron representative.
Note 9
If the inverter is operated outside the region shown in the graph in the derating
curve, the inverter may be damaged or its service life may be shortened. Set
Carrier Frequency Adjustment in accordance with the expected output
current level. See derating curve section for the detailed information of the
inverter operating range.
Note 10
The storage temperature refers to the short-term temperature during transpor-
tation.
Note 11
Conforms to the test method specified in JIS C0040 (1999). For the model
types excluded in the standard specifications, contact your Omron sales rep-
resentative.
Note 12
Watt losses are calculated values based on specification of main semi-con-
ductors. You must take suitable margin when designing cabinet based on
these values. Otherwise there is a possibility of heating trouble.

Derating Curves
The maximum available inverter current output is limited by the carrier fre-
quency and ambient temperature. Choosing a higher carrier frequency tends
to decrease audible noise, but it also increases the internal heating of the
inverter, thus decreasing (derating) the maximum current output capability.
Ambient temperature is the temperature just outside the inverter housing such
as inside the control cabinet where the inverter is mounted. A higher ambient
temperature decreases (derates) the inverter's maximum current output
capacity.
An inverter up to 4.0 kW may be mounted individually in an enclosure or side-
by-side with other inverter(s) as shown below. Side-by-side mounting causes
greater derating than mounting inverters separately. Graphs for either mount-
ing methods are included in this section. Refer to Installation Environment
clearance on page 31 for minimum clearance dimensions for both mounting
configurations.

Introduction to Variable-Frequency Drives

The Purpose of Motor Speed Control for Industry
Omron inverters provide speed control for 3-phase AC induction motors. You
connect AC power to the inverter, and connect the inverter to the motor. Many
applications benefit from a motor with variable speed, in several ways:
• Energy savings - HVAC
• Need to coordinate speed with an adjacent process - textile and printing
presses
• Need to control acceleration and deceleration (torque)
• Sensitive loads - elevators, food processing, pharmaceuticals
1-3-2
What is an Inverter
The term inverter and variable-frequency drive are related and somewhat
interchangeable. An electronic motor drive for an AC motor can control the
motor's speed by varying the frequency of the power sent to the motor.
An inverter, in general, is a device that converts DC power to AC power. The
figure below shows how the variable-frequency drive employs an internal
inverter. The drive first converts incoming AC power to DC through a rectifier
bridge, creating an internal DC bus voltage. Then the inverter circuit converts
the DC back to AC again to power the motor. The special inverter can vary its
output frequency and voltage according to the desired motor speed.
The simplified drawing of the inverter shows three double-throw switches. In
Omron inverters, the switches are actually IGBTs (insulated gate bipolar tran-
sistors). Using a commutation algorithm, the microprocessor in the drive
switches the IGBTs on and off at a very high speed to create the desired out-
put waveforms. The inductance of the motor windings helps smooth out the
pulses.
1-3-3
Torque and Constant Volts/Hertz Operation
In the past, AC variable speed drives used
an open loop (scalar) technique to control
speed. The constant-volts-hertz operation
maintains a constant ratio between the
applied voltage and the applied frequency.
With these conditions, AC induction motors
inherently delivered constant torque across
the operating speed range. For some appli-
cations, this scalar technique was ade-
quate.

Introduction to Variable-Frequency Drives
Section 1-3
Today, with the advent of sophisticated microprocessors and digital signal pro-
cessors (DSPs), it is possible to control the speed and torque of AC induction
motors with unprecedented accuracy. The MX2 utilizes these devices to per-
form complex mathematical calculations required to achieve superior perfor-
mance. You can choose various torque curves to fit the needs of your
application. Constant torque applies the same torque level across the fre-
quency (speed) range. Variable torque, also called reduced torque, lowers the
torque delivered at mid-level frequencies. A torque boost setting will add addi-
tional torque in the lower half of the frequency range for the constant and vari-
able torque curves. With the free-setting torque curve feature, you can specify
a series of data points that will define a custom torque curve to fit your appli-
cation.
1-3-4
Inverter Input and Three-phase Power
The Omron MX2 Series of inverters includes two sub-groups: the 200 V class
and the 400V class inverters. The drive described in this manual may be used
in either the United States or Europe, although the exact voltage level for com-
mercial power may be slightly different from country to country. Accordingly, a
200 V class inverter requires (nominal) 200 to 240 VAC, and 400 V class
inverter requires from 380 to 480 VAC.
The 200 V class inverters MX2-B accept single-phase 200 V class input volt-
age, those MX2-2 three-phase power only. All 400 V class inverters require
three-phase power supply.
!Tip
If your application only has single phase power available, refer to MX2 inverter
of 3HP or less; they can accept single phase input power. Note: Larger mod-
els may be able to accept single-phase with derating. Contact your Omron
distributor for assistance.
The common terminology for single phase power is line (L) and Neutral (N).
Three-phase power connections are usually labeled Line 1 [R/L1], Line 2 [S/
L2] and Line 3 [T/L3]. In any case, the power source should include an earth
ground connection. That ground connection will need to connect to the
inverter chassis and to the motor frame (see “Wire the Inverter Output to
Motor” in section 2-3-12 (page 51) and “Inverter output terminal (U/T1, V/T2,
W/T3)” in section 2-3-9 (page 47)).
1-3-5
Inverter Output to the Motor
The AC motor must be connected only to the inverter's
output terminals. The output terminals are uniquely
labeled (to differentiate them from the input terminals)
with the designations U/T1, V/T2, and W/T3. This cor-
responds to typical motor lead connection designations
T1, T2, and T3. It is often not necessary to connect a
particular motor lead for a new application. The conse-
quence of swapping any two of the three connections is
the reversal of the motor direction. In applications
where reversed rotation could cause equipment dam-
age or personnel injury, be sure to verify direction of
rotation before attempting full-speed operation.
For safety to personnel, you must connect the motor chassis ground to the
ground connection at the bottom of the inverter housing.
Notice the three connections to the motor do not include one marked “Neutral”
or “Return”. The motor represents a balanced “Y” impedance to the inverter,
so there is no need for a separate return. In other words, each of the three
“Hot” connections serves also as a return for the other connections, because
of their phase relationship.

Introduction to Variable-Frequency Drives
Section 1-3
The Omron inverter is a rugged and reliable device. The intention is for the
inverter to assume the role of controlling power to the motor during all normal
operations. Therefore, this manual instructs you not to switch off power to the
inverter while the motor is running (unless it is an emergency stop). Also, do
not install or use disconnect switches in the wiring from the inverter to the
motor (except thermal disconnect). Of course, safety-related devices such as
fuses must be in the design to break power during a malfunction, as required
by NEC and local codes.
1-3-6
Intelligent Functions and Parameters
Much of this manual is devoted to describing how to use inverter functions
and how to configure inverter parameters. The inverter is micro-processor-
controlled, and has many independent functions. The microprocessor has an
on-board EEPROM for parameter storage. The inverter's front panel keypad
provides access to all functions and parameters, which you can access
through other devices as well. The general name for all these devices is the
digital operator, integrated operator, or digital operator panel. Chapter 2 will
show you how to get a motor running, using a minimal set of function com-
mands or configuring parameters.
The optional read/write programmer will let you read and write inverter
EEPROM contents from the programmer. This feature is particularly useful for
OEMs who need to duplicate a particular inverter's settings in many other
inverters in assembly-line fashion.
1-3-7
Braking
In general, braking is a force that attempts to slow or stop motor rotation. So it
is associated with motor deceleration, but may also occur even when the load
attempts to drive the motor faster than the desired speed (overhauling). If you
need the motor and load to decelerate quicker than their natural deceleration
during coasting, we recommend installing a braking resistor. The dynamic
braking unit (built into MX2) sends excess motor energy into a resistor to slow
the motor and load (See “Introduction” in section 5-1 (page 255) and
“Dynamic Braking” in section 5-3 (page 262) for more information). For loads
that continuously overhaul the motor for extended periods of time, the MX2
may not be suitable (contact your Omron distributor).
The inverter parameters include acceleration and deceleration, which you can
set to match the needs of the application. For a particular inverter, motor, and
load, there will be a range of practically achievable accelerations and deceler-
ations.
Introduction to Variable-Frequency Drives
Section 1-3
1-3-8
Velocity Profiles
The MX2 inverter is capable of
sophisticated
speed
control.
A
graphical representation of that
capability will help you understand
and configure the associated param-
eters. This manual makes use of the
velocity profile graph used in indus-
try (shown at right). In the example,
acceleration is a ramp to a set
speed, and deceleration is a decline
to a stop.
Acceleration and deceleration set-
tings specify the time required to go
from a stop to maximum frequency
(or vise versa). The resulting slope
(speed change divided by time) is
the acceleration or deceleration. An
increase in output frequency uses
the acceleration slope, while a
decrease uses the deceleration
slope. The accel or decel time a par-
ticular speed change depends on
the starting and ending frequencies.
However, the slope is constant, corresponding to the full-scale accel or decel
time setting. For example, the full-scale acceleration setting (time) may be 10
seconds - the time required to go from 0 to 60 Hz.
The MX2 inverter can store up to 16
preset speeds. And, it can apply
separate acceleration and decelera-
tion transitions from any preset to
any other preset speed. A multi-
speed profile (shown at right) uses
two or more preset speeds, which
you can select via intelligent input
terminals. This external control can
apply any preset speed at any time.
Alternatively, the selected speed is infinitely variable across the speed range.
You can use the potentiometer control on the keypad for manual control. The
drive accepts analog 0-10 VDC signals and 4-20 mA control signals as well.
The inverter can drive the motor in
either direction. Separate FW and
RV commands select the direction of
rotation. The motion profile example
shows a forward motion followed by
a reverse motion of shorter duration.
The speed presets and analog sig-
nals control the magnitude of the
speed, while the FWD and REV
commands determine the direction
before the motion starts.
Note The MX2 can move loads in both directions. However, it is not designed for
use in servo-type applications that use a bipolar velocity signal that deter-
mines direction.

Frequently Asked Questions

Frequently Asked Questions
Q. What is the main advantage in using an inverter to drive a motor, com-
pared to alternative solutions?
A. An inverter can vary the motor speed with very little loss of efficiency,
unlike mechanical or hydraulic speed control solutions. The resulting ener-
gy savings usually pays for the inverter in a relatively short time.
Q. The term “inverter” is a little confusing, since we also use “drive” and
“amplifier” to describe the electronic unit that controls a motor. What does
“inverter” mean?
A. The term inverter, drive, and amplifier are used somewhat interchange-
ably in industry. Nowadays, the term drive, variable-frequency drive, vari-
able-speed drive, and inverter are generally used to describe electronic,
microprocessor-based motor speed controllers. In the past, variable-
speed drive also referred to various mechanical means to vary speed. Am-
plifier is a term almost exclusively used to describe drives for servo or step-
per motors.
Q. Although the MX2 inverter is a variable speed drive, can I use it in a fixed-
speed application?
A. Yes, sometimes an inverter can be used simply as a “soft-start” device,
providing controlled acceleration and deceleration to a fixed speed. Other
functions of the MX2 may be useful in such applications, as well. However,
using a variable speed drive can benefit many types of industrial and com-
mercial motor applications, by providing controlled acceleration and decel-
eration, high torque at low speeds, and energy savings over alternative
solutions.
Q. Can I use an inverter and AC induction motor in a positioning application?
A. That depends on the required precision, and the slowest speed the mo-
tor must turn and still deliver torque. The MX2 inverter will deliver full
torque while turning the motor at 6Hz (180RPM). DO NOT use an inverter
if you need the motor to stop and hold the load position without the aid of
a mechanical brake (use a servo or stepper motion control system).
Q. Can the inverter be controlled and monitored via a network?
A. Yes. MX2 inverters have built-in ModBus communications. See Appen-
dix B for more information on network communications.
Q. Why does the manual or other documentation use terminology such as
“200 V class” instead of naming the actual voltage, such as “230 VAC”
A. A specific inverter model is set at the factory to work across a voltage
range particular to the destination country for that model. The model spec-
ifications are on the label on the side of the inverter. A European 200V
class inverter (“EU” marking) has different parameter settings than a USA
200 V class.
Q. Why doesn't the motor have a neutral connection as a return to the
inverter?
A. The motor theoretically represents a “balanced Y” load if all three stator
windings have the same impedance. The Y connection allows each of the
three wires to alternatively serve as input or return on alternate half-cycle.
Frequently Asked Questions
Section 1-4
Q. Does the motor need a chassis ground connection?
A. Yes, for several reasons. Most importantly, this provides protection in the
event of a short in the motor that puts a hazardous voltage on its housing.
Secondly, motors exhibit leakage current that increase with aging. Lastly,
a grounded chassis generally emits less electrical noise than an unground-
ed one.
Q. What type of motor is compatible with the Omron inverters?
A. Motor type - It must be a three-phase AC induction motor. Use an in-
verter-grade motor that has at least 800V insulation for 200V class invert-
ers, or 1600V insulation for 400V class.
Motor size - In practice, it's better to find the right size motor for your ap-
plication; then look for the inverter to match the motor.
Note There may be other factors that will affect motor selection, including heat dis-
sipation, motor operating speed profile, enclosure type, and cooling method.
Q. How many poles should the motor have?
A. Omron inverters can be configured to operate motors with 2, 4, 6, or 8
poles. The greater the number of the poles, the slower the top motor speed
will be, but it will have higher torque at the base speed.
Q. Will I be able to add dynamic (resistive) braking to my Omron MX2 drive
after the initial installation?
A. Yes, the MX2 inverter already has a dynamic braking circuit built in. Just
add the resistor sized to meet the braking requirements. For more informa-
tion, contact your nearest Omron representative.
Q. How will I know if my application will require resistive braking?
A. For new applications, it may be difficult to tell before you actually test a
motor/drive solution. In general, some application can rely on system loss-
es such as friction to serve as the deceleration force, or otherwise can tol-
erate a long decel time. These applications will not need dynamic braking.
However, applications with a combination of a high-inertia load and a re-
quired short decel time will need dynamic braking. This is a physics ques-
tion that may be answered either empirically or through extensive
calculations.
Q. Several options related to electrical noise suppression are available for the
Omron inverters. How can I know if my application require any of these
options?
A. The purpose of these noise filters is to reduce the inverter electrical
noise so the operation of nearby electrical devices is not affected. Some
applications are governed by particular regulatory agencies, and noise
suppression is mandatory . in those cases, the inverter must have the cor-
responding noise filter installed. Other applications may not need noise
suppression, unless you notice electrical interference with the operation of
other devices.
Q. The MX2 features a PID control. PID loops are usually associated with
water control, flow control processes, heating, or process industries in gen-
eral. How could the PID loop feature be useful in my application?
A. You will need to determine the particular main variable in your applica-
tion the motor affects. That is the process variable (PV) for the motor. Over
time, a faster motor speed will cause a faster change in the PV than a slow
motor speed will. By using the PID loop feature, the inverter commands the
motor to run at the optimal speed required to maintain the PV at the de-
sired value for current conditions. Using the PID loop feature will require an
additional sensor and other wiring, and is considered an advanced appli-
cation.

Unpacking and Inspection
Please take a few moments to unpack your new MX2 inverter and perform
these steps:
1. Look for any damage that may have occurred during transportation.
2. Verify the contents of the box.
3. Inspect the specifications label on the side of the inverter. Make sure it
matches the product part number you ordered.
2-1-2
Main Physical Features
The MX2 Series inverters vary in size
according to the current output rating and
motor size for each model number. All
feature the same basic Keypad and con-
nector interface for consistent ease of
use. The inverter construction has a heat
sink at the back of the housing. The larger
models include a fan to enhance heat sink
performance. The mounting holes are
predrilled in the heat sink for your conve-
nience. Smaller models have two mount-
ing holes, while larger ones have four. Be
sure to use all the mounting holes pro-
vided.
Never touch the heat sink during or just
after operation; it can be very hot.
The electronics housing and front panel
are built onto the front of the heat sink.
Inverter Keypad - The inverter uses a
digital operator interface, or keypad. The
four-digit display can show a variety of
performance parameters. LEDs indicate
whether the display units are Hertz or
Amperes. Other LEDs indicate Power
(external), and Run/Stop mode and Pro-
gram/Monitor Mode status. Membrane
keys Run and Stop/Reset control monitor
operation. The
,
,
and
keys allow an operator to navigate to the
inverter's functions and parameter values.
The
key is used when changing a
parameter.

Section 2-1
Power Wiring Access - First, ensure no power source is connected to the
inverter. If power has been connected, verify that the Power LED is OFF and
then wait ten minutes after power down to proceed. After removing the termi-
nal cover and front housing cover, the housing partitions that cover the power
and motor wiring exits will be able to slide upward as shown below.
Notice the four wire exit slots in the housing partition. This helps keep the
power and motor wiring (to the left) separated from the signal-level logic or
analog wiring (to the right).
Remove the housing partition and as shown as set them aside in a secure
place while wiring. Be sure to replace them afterward. Never operate the
inverter with the partition removed or the front housing cover removed.
The power input and motor 3-phase wiring connect to the lower row of the ter-
minals. The upper row of power terminals connect to optional braking units or
DC link choke.
The following section in this chapter will describe system design and guide
you through a step-by-step installation process. After the section on wiring,
this chapter will show how to use the front panel keys to access functions and
edit parameters.
Note The housing partition can be removed without removing the front cover in the
following models.

Basic System Description
A motor control system will obviously include a motor and inverter, as well as
a circuit breaker or fuses for safety. If you are connecting a motor to the
inverter on a test bench just to get started, that's all you may need for now. But
a system can also have a variety of additional components. Some can be for
noise suppression, while others may enhance the inverter's braking perfor-
mance. The figure and table below show a system with all the optional com-
ponents you might need in your finished application.
Note Note that some components are required for regulatory agency compliance
(see SECTION 5 Inverter System Accessories and Appendix D CE-EMC
Installation Guidelines).

ance.
Input-side
AC Reactor
This is useful in reducing low frequency
harmonics distortion induced on the
power supply lines and as consequence
improve the power factor. WARNING:
Some applications must use an input-
side AC Reactor to prevent inverter
damage. See Warning on next page.
EMC filter
(for CE appli-
cations, see
Appendix D)
Reduces the conducted high frequency
noise on the power supply wiring
between the inverter and the power dis-
tribution system. Connect to the inverter
primary (input) side.
DC link
choke
Reduce harmonics generated by the
inverter motor driving section, by
smoothing the current demand of the
capacitors.
Braking
Resistor
Used to disipate regenerative energy
from the motor that is accumulated into
the DC bus charging the capacitors and
increasing the voltage.
Radio noise
output filter
Electrical noise interference may occur
on nearby equipment such as a radio
receiver. This magnetic choke filter
helps reduce very high frequency radi-
ated noise (can also be used on input).
Output-side
AC Reactor
This reactor in its standard type (only L
inductor), prevents the high voltage
ringing of PWM modulation to reach the
motor, compensating for the capacity of
the motor cables, specially with long
lengths.
For more effective (and expensive)
options, like sinus filter (targetting net-
work-like waveforms) or dV/dt filters,
please check with your dealer.
Step-by-Step Basic Installation
Section 2-3
!WARNING In the cases below involving a general-purpose inverter, a large peak current
can flow on the power supply side, sometimes destroying the converter mod-
ule:
1. The unbalance factor of the power supply is 3% or higher.
2. The power supply capacity is at least 10 times greater than the inverter
capacity (or the power supply capacity is 500k VA or more).
3. Abrupt power supply changes are expected, due to conditions such as:
a. Several inverters are interconnected with a short bus.
b. A thyristor converter and an inverter are interconnected with a short
bus.
c. An installed phase advance capacitor opens and closes.
Where these conditions exist or when the connected equipment must be
highly reliable, you MUST install an input-side AC reactor of 3% (at a voltage
drop at rated current) with respect to the supply voltage on the power supply
side. Also, where the effects of an indirect lightning strike are possible, install
a lightning conductor.

Step-by-Step Basic Installation
This section will guide you through the following basic steps of installation:
Note If the installation is in an EU country, study the EMC installation guidelines in
Appendix D CE-EMC Installation Guidelines.
Choosing a Mounting Location
Study the following caution messages associated with mounting the inverter.
This is the time when mistakes are most likely to occur that will result in
expensive rework, equipment damage, or personal injury.
!WARNING Hazard of electrical shock. Never touch the naked PCB (printed circuit board)
or bus bars while the unit is powered up. Even for switch portion, the inverter
must be powered OFF before you change.
!Caution Be sure to install the unit on flame-resistant material such as steel plate.
Otherwise, there is the danger of fire.
!Caution Be sure not to place any flammable materials near the inverter. Otherwise,
there is the danger of fire.

Mounting MX2 IP54 Mounting Plate
All housings use for M6 mounting screws. Be sure to use lock washers or
other means to ensure screws do not loosen due to a vibration.
2-3-2
Installation Environment clearance
Make sure the ambient temperature remains within the rated range (10 to
50C). Take note that if the ambient temperature reaches or exceeds 40C,
the carrier frequency and output current must be derated (check derating
tables per each inverter model in Derating Curves on page 9). If the Inverter is
used in an environment exceeding the allowable operating temperature range,
the product life of the Inverter (specifically, the capacitor) will be shortened.
Measure and check the temperature approx. 5 cm from the bottom center of
the Inverter body.
Provide sufficient space around the Inverter because it can become very hot
(up to 150C or so). Or provide the right air ventilation forced cooling flow
when designing the enclosure :
Air flow
100 mm or more
50 mm or more
Inverter
Wall
Provide sufficient
space so that the top
and bottom wiring
ducts, etc. will not
obstruct the flows of
cooling air.
100 mm or more
Step-by-Step Basic Installation
Section 2-3
Keep the Inverter away from heating elements (such as a Braking Resistor,
reactor, etc.).
Although side-by-side installation is possible. The ambient temperature of the
installation site must not exceed 40C and the carrier frequency and output
current must be derated if side-by-side installation is used. For details check
Derating Curves on page 9.
Make sure that the humidity in the installation site is within the allowable oper-
ating range (20% to 90% RH), as defined in the standard specifications.
Heat Radiation from Inverter
!Caution Be sure to maintain the specified clearance area around the inverter and to
provide adequate ventilation. Otherwise, the inverter may overheat and cause
equipment damage or fire.

Determining Wire and Fuse Sizes
The maximum motor currents in your application determines the recom-
mended wore size. The following table gives the wire size in AWG. The
“Power Lines” column applies to the inverter input power, output wires to the
motor, the earth ground connection, and any other components shown in the
“Basic System Description” on page 28. The “Signal Lines” column applies to
any wire connecting to the two green connectors just inside the front cover
panel.
Note 1
Field wiring must be made by a UL-Listed and CSA-certified closed-loop ter-
minal connector sized for the wire gauge involved. Connector must be fixed by
using the crimping tool specified by the connector manufacturer.
Note 2
Be sure to consider the capacity of the circuit breaker to be used.
Note 3
Be sure to use a larger wire gauge if power line length exceeds 66 ft. (20 m).
Note 4
Use 18 AWG / 0.75 mm² wire for the alarm signal wire ([AL0], [AL1], [AL2] ter-
minals).

Terminal Dimensions and Torque Specs
The terminal screw dimensions for all MX2 inverters are listed in table below.
This information is useful in sizing spade lug or ring lug connectors for wire
terminations.
!Caution Tighten the screws with the specified torque in the table below. Check for any
loosening of screws. Otherwise, there is the danger of fire.
2-3-8
Inverter Supply Input (R/L1, S/L2, T/L3)
Step 3
In this step, you will connect wiring to the input of the inverter. First, you must
determine whether the inverter model you have required three-phase power
only with terminals [R/L1], [S/L2], and [T/L3], or single-phase power only
with terminals [L1] and [N]. Refer to the specifications label (on the side of the
inverter) for the acceptable power source types!
2-3-8-1
Earth leakage circuit breaker
Use an earth leakage breaker for circuit (wiring) protection between the power
supply and the main power supply terminals (R/L1, S/L2, T/L3).
An earth leakage breaker may malfunction at high frequencies as those gen-
erated by an inverter. Use an earth leakage breaker with a large high-fre-
quency sensitive current rating.
When sensitivity of 30mA or even less earth leakage maybe required in cer-
tain applications (e.g. domestic), short motor cable and convenient low-leak-
age EMC filters should be selected. Check with your supplier for additional
indications.
2-3-8-2
Magnetic contactor
When the Inverter protective function is activated, your system may fail or an
accident may occur. Connect a magnetic contactor to turn off the Inverter
power supply.
Do not start or stop the Inverter by switching ON/OFF the magnetic contactor
provided in the Inverter power supply input (primary) circuit and output (sec-
ondary) circuit.To start or stop the Inverter via an external signal, use the
operation command terminals (FW, RV) on the control circuit terminal block.
Do not use this Inverter with an input phase loss connection. The Inverter
operating with 1-phase input may be causing a trip (due to undervoltage,
overcurrent, etc.) or damage to the Inverter.
Do not turn on the power and then turn it off again more than once every 3
minutes. Doing so may damage the Inverter.

Inverter output terminal (U/T1, V/T2, W/T3)
For connection of the output terminal, use the compatible cable or a cable with
a larger section. Otherwise, the output voltage between the Inverter and the
motor may drop.
Do not mount a phase advance capacitor or surge absorber, because these
devices may cause the Inverter to trip or cause damage to the capacitor or
surge absorber.
If the cable length exceeds 20 m (particularly, with 400 V class), a surge volt-
age may be generated at the motor terminal depending on stray capacitance
or inductance of the cable, causing the motor to risk his isolation (depending
on motor isolation class and conditions).
To suppress surge voltage, output filters are recommended. From simple
choke and output dV/dt filters to sinus filters.
To connect several motors, provide a thermal protection relay for each, as the
inverter can not recognize how current is shared among the motors.
The RC value of each thermal relay should be 1.1 times larger than the motor
rated current.The relay may trip earlier depending on the cable length.In this
case, connect an AC reactor to the Inverter output.
2-3-10 DC Reactor Connection (+1, P/+2)
This terminal is used to connect the optional DC reactor.
By factory default, a shorting bar has been connected between terminals +1
and P/+2. Before connecting the DC reactor, remove this shorting bar.
The length of the DC reactor connection cable should be 5 m or shorter.
If the DC reactor is not being used, do not remove the shorting bar.
If you remove the shorting bar without connecting the DC reactor, no power is
supplied to the Inverter main circuit, disabling operation.

ity should be five times that of the inverter (kVA).
!Caution Be sure that the input voltage matches the inverter specifications:
• Single-phase 200 to 240 V 50/60 Hz(0.1 kW~2.2 kW) for 3G3MX2-AB
models
• Three-phase 200 to 240 V 50/60 Hz (0.1 kW~15 kW) for 3G3MX2-A2
models
• Three-phase 380 to 480 V 50/60 Hz (0.4 kW~15 kW) for 3G3MX2-A4
models
!Caution Be sure not to power a three-phase-only inverter with single phase power.
Otherwise, there is the possibility of damage to the inverter and the danger of
fire.

!Caution Be sure not to connect an AC power supply to the output terminals. Other-
wise, there is the possibility of damage to the inverter and the danger of injury
and/or fire.
!Caution Remarks for using ground fault interrupter breakers in the main power supply:
Adjustable frequency inverter with integrated CE-filters and shielded
(screened) motor cables have a higher leakage current toward earth GND.
Especially at the moment of switching ON this can cause an inadvertent trip of
ground fault interrupters. Because of the rectifier on the input side of the
inverter there is the possibility to stall the switch-off function through small
amounts of DC current.
Please observe the following:
• Use only short time-invariant and pulse current-sensitive ground fault
interrupters with higher trigger current.
• Other components should be secured with separate ground fault inter-
rupters.
• Ground fault interrupters in the power input wiring of an inverter are not an
absolute protection against electric shock.
!Caution Be sure to install a fuse in each phase of the main power supply to the
inverter. Otherwise, there is the danger of fire.
!Caution For motor leads, ground fault interrupter breakers and electromagnetic con-
tactors, be sure to size these components properly (each must have the
capacity for rated current and voltage). Otherwise, there is the danger of fire.

2-3-12 Wire the Inverter Output to Motor
Step 4
The process of motor selection is beyond the scope of this manual. However,
it must be an AC induction motor with three phases. It should also come with a
chassis ground lug. If the motor does not have three power input leads, stop
the installation and verify the motor type. Other guidelines for wiring the motor
include:
• Use an inverter-grade motor for maximum motor life (1600 V insulation).
• For standard motors, use the AC reactor accessory if the wiring between
the inverter and motor exceeds 10 meters in length.
Simply connect the motor to the terminals [U/T1], [V/T2], and [W/T3] as
shown in page 46 to page 49. This is a good time to connect the chassis
ground lug on the drive as well. The motor chassis ground must also connect
to the same point. Use a star ground (single-point) arrangement, and never
daisy-chain the grounds (point-to-point).
• Check the mechanical integrity of each wire crimp and terminal connec-
tion.
• Replace the housing partition that covers access to the power connec-
tions.
Special care to be taken when motor is connected through long wires
2-3-13 Ground Terminal
To prevent electric shock, be sure to ground the Inverter and the motor.
The 200 V class should be connected to the ground terminal under Class D
grounding conditions (conventional Class 3 grounding conditions: 100 or
less ground resistance), The 400 V class should be connected to the ground
terminal under Class C grounding conditions (conventional special Class 3
grounding conditions: 10 or less ground resistance).
For the ground cable, use the compatible cable or a cable with a larger diame-
ter. Make the cable length as short as possible.
When several Inverters are connected, the ground cable must not be con-
nected across several Inverters, and must not be looped. Otherwise, the
Inverter and surrounding control machines may malfunction.
2-3-14 Logic Control Wiring
After completing the initial installation and powerup test in this chapter, you
may need to wire the logic signal connector for your application. For new
inverter users/applications, we highly recommend that you first complete the
powerup test in this chapter without adding any logic control wiring. As a quick
reference here is included the control connection diagram. But for more

2-4-1
Goals for the Powerup Test
If there are any exceptions to the above conditions at this step, please take a
moment to take any measures necessary to reach this basic starting point.
The specific goals of this powerup test are:
1.
Verify that the wiring to the power supply and motor is correct.
2.
Demonstrate that the inverter and motor are generally compatible.
3.
Get an introduction to the use of the built-in operator keypad.
The powerup test gives you an important starting to ensure a safe and suc-
cessful application of the Omron inverter. We highly recommend performing
this test before proceeding to the other chapters in this manual.
2-4-2
Pre-test and Operational Precautions
The following instructions apply to the powerup test, or to any time the inverter
is powered and operating. Please study the following instructions and mes-
sages before proceeding with the powerup test.
1.
The power supply must have fusing suitable for the load. Check the fuse
size chart presented in Step 5, if necessary.
2.
Be sure you have access to a disconnect switch for the drive input power
if necessary. However, do not turn OFF power during inverter operation un-
less it is an emergency.
!Caution The heat sink fins will have a high temperature. Be careful not to touch them.
Otherwise, there is the danger of getting burned.
!Caution The operation of the inverter can be easily changed from low speed to high
speed. Be sure to check the capability and limitations of the motor and
machine before operating the inverter. Otherwise, there is the danger of injury.
!Caution If you operate a motor at a frequency higher than the inverter standard default
setting (50 Hz/60 Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequen-
cies after getting their approval. Otherwise, there is the danger of equipment
damage and/or injury.
!Caution Check the following before and during the Powerup test. Otherwise, there is
the danger of equipment damage.
• Is the shorting bar between the [+1] and [+] terminals installed? DO NOT
power or operate the inverter if the jumper is removed.
• Is the direction of the motor rotation correct?
• Did the inverter trip during acceleration or deceleration?
• Were the rpm and frequency meter readings as expected?
• Were there any abnormal motor vibration or noise?
2-4-3
Powering the Inverter
If you have followed all the steps, cautions and warnings up to this point,
you're ready to apply power. After doing so, the following events should occur:
• The POWER LED will illuminate.
• The numeric (7-segment) LEDs will display a test pattern, then stop at
..
• The Hz LED will be ON.
If the motor starts running unexpectedly or any other problem occurs, press
the STOP key. Only if necessary should you remove power to the inverter as a
remedy.
Note If the inverter has been previously powered and programmed, the LEDs (other
than the POWER LED) may illuminate differently than as indicated above. If
necessary, you can initialize all parameters to the factory default settings. See
“Restoring Factory Default Settings” on page 279.

Keypad Navigation Map
The MX2 Series inverter drives have many programmable functions and
parameters. Chapter 3 will cover these in detail, but you need to access just a
few items to perform the powerup test. The menu structure makes use of
function codes and parameter codes to allow programming and monitoring
with only a 4-digit display and keys and LEDs. So, it is important to become
familiar with the basic navigation map of parameters and functions in the dia-
gram below. You may later use this map as a reference.

Selecting Functions and Editing Parameters
To prepare to run the motor in the powerup test, this section will show how to
configure the necessary parameters:
1.
Select the digital operator as the source of motor speed command
().
2.
Select the digital operator as the source of the RUN command ().
3.
Set the motor base frequency () and AVR voltage of the motor ().
4.
Set the motor current for proper thermal protection ().
5.
Set the number of poles for the motor ().
The following series of programming tables are designed for successive use.
Each table uses the previous table's final state as the starting point. There-
fore, start with the first and continue programming until the last one. If you get
lost or concerned that some of the other parameters setting may be incorrect,
refer to “Restoring Factory Default Settings” on page 279.
Prepare to Edit Parameters – This sequence begins with powering ON the
inverter, then it shows how to navigate to the “A” Group parameters for subse-
quent settings. You can also refer to the “Keypad Navigation Map” on page 60
for orientation throughout the steps.
1. Select the digital operator for Speed Command – The inverter output
frequency can be set from several sources, including an analog input, mem-
ory setting, or the network, for example. The powerup test uses the keypad as
the speed control source for your convenience. Note that the default setting
depends on the country.
2. Select the digital operator for RUN
Command – To RUN command causes the
inverter to accelerate the motor to the
selected speed. The Run command can
arrive from various sources, including the
control terminals, the Run key on the keypad
or the network. In the figure to the right,
notice the Run Key Enable LED, just above
the Run key. If the LED is ON, the Run key is
already selected as the source, and you may
skip this step. Note that the default setting
depends on the country.

Note After completing the steps above, the Run Key Enable LED will be ON. This
does not mean the motor is trying to run; it means that the RUN key is now
enabled. DO NOT press the RUN key at this time – complete the parameter
setup first.
3. Set the Motor Base Frequency and AVR voltage of the motor – The
motor is designed to operate at a specific AC frequency. Most commercial
motors are designed for 50/60 Hz operation. First, check the motor specifica-
tions. Then follow the steps below to verify the setting or correct it for your
motor. DO NOT set it greater than 50/60 Hz unless the motor manufacturer
specifically approves operation at the higher frequency.
!Caution If you operate a motor at a frequency higher than the inverter standard default
setting (50 Hz/60 Hz), be sure to check the motor and machine specifications
with the respective manufacturer. Only operate the motor at elevated frequen-
cies after getting their approval. Otherwise, there is the danger of equipment
damage.
Set the AVR Voltage Setting – The inverter has an Automatic Voltage Regula-
tion (AVR) function. It adjusts the output voltage to match the motor's name-
plate voltage rating. The AVR smoothes out fluctuation in the input power
source, but note that it does not boost the voltage in the event of a brown-out.
Use the AVR setting () that most closely matches the one for your motor.

To set the motor voltage, follow the steps on the following table.
4. Set the Motor Current – The inverter has thermal overload protection that
is designed to protect the inverter and motor from overheating due to an
excessive load. The inverter's uses the motor's current rating to calculate the
time-based heating effect. This protection depends on using correct current
rating for your motor. The level of electronic thermal setting, parameter ,
is adjustable from 20% to 100% of the inverter's rated current. A proper con-
figuration will also help prevent unnecessary inverter trip events.
Read the motor's current rating on its manufacturer's nameplate. Then follow
the steps below to configure the inverter's overload protection setting.

5. Set the Number of Motor Poles – The motor's internal winding arrange-
ment determines its number of magnetic poles. The specification label on the
motor usually indicates the number of poles. For proper operation, verify the
parameter setting matches the motor poles. Many industrial motors have four
poles, corresponding to the default setting in the inverter ().
Follow the steps in the table below to verify the motor poles setting and
change if necessary (the table resumes action from the end of the previous
table.)
This step concludes the parameter setups for the inverter. You are almost
ready to run the motor for the first time!
!Tip
If you became lost during any of these steps, first observe the state of the
PRG LED. Then study the “Keypad Navigation Map” on page 60 to determine
the current state of the keypad controls and display. As long as you do not
press the
key, no parameter will be changed by keypad entry errors.
Note that power cycling the inverter causes it to power up Monitor Mode, dis-
playing the value for (output frequency).
The next section will show you how to monitor a particular parameter from the
display. Then you will be ready to run the motor.

Monitoring Parameters with the Display
After using the keypad for parameter editing,
it's a good idea to switch the inverter from
Program Mode to Monitor Mode. The PRG
LED will be OFF, and the Hertz or Ampere
LED indicates the display units.
For the powerup test, monitor the motor
speed indirectly by viewing the inverter's out-
put frequency. The output frequency must not
be confused with base frequency (50/60 Hz) of the motor, or the carrier fre-
quency (switching frequency of the inverter, in the kHz range). The monitoring
functions are in the “D” list, located near the top left of the “Keypad Navigation
Map” on page 60.
Output frequency (speed) set – Resuming keypad operation from the previ-
ous table, follow the steps below.

run the motor! First, review this checklist:
1.
Verify the power LED is ON. If not, check the power connections.
2.
Verify the Run Key Enable LED is ON. If it is OFF, check the setting.
3.
Verify the PRG LED is OFF. If it is ON, review the instructions above.
4.
Make sure the motor is disconnected from any mechanical load.
5.
Now, press the RUN key on the keypad. The RUN LED will turn ON.

Powerup Test Observations and Summary
Step 7
Reading this section will help you make some useful observations when first
running the motor.
Error Codes – If the inverter displays an error code (format is “ xx”), see
“Monitoring Trip Events, History, & Conditions” on page 273 to interpret and
clear the error.
Acceleration and Deceleration – The MX2 inverter has programmable
acceleration and deceleration value. The test procedure left these at the
default value, 10 seconds. You can observe this by setting the frequency
at about half speed before running the motor. Then press RUN, and the motor
will take 5 seconds to reach a steady speed. Press the STOP key to see a
5 second deceleration to a STOP.
State of Inverter at Stop – If you adjust the motor's speed to zero, the motor
will slow to a near stop, and the inverter turns the outputs OFF. The high-per-
formance MX2 can rotate at a very slow speed with high torque output, but not
zero (must use servo systems with position feedback for that feature). This
characteristic means you must use a mechanical brake for some applications.
Interpreting the Display – First, refer to the output frequency display read-
out. The maximum frequency setting (parameter ) defaults to 50 Hz or
60 Hz (Europe and United States, respectively) for your application.
Example: Suppose a 4-pole motor is rated for 60 Hz operation, so the inverter
is configured to output 60 Hz at full scale. Use the following formula to calcu-
late the rpm.
The theoretical speed for the motor is 1800 rpm (speed of torque vector
rotation). However, the motor cannot generate torque unless its shaft turns at
a slightly different speed. This difference is called slip. So it's common to see
a rated speed of approximately 1750 rpm on a 60 Hz, 4-pole motor. Using a
tachometer to measure shaft speed, you can see the difference between the
inverter output frequency and the actual motor speed. The slip increases
slightly as the motor's load increases. This is why the inverter output value is
called “frequency”, since it is not exactly equal to motor speed.
Run/Stop Versus Monitor/Program
Modes – The Run LED on the inverter
is ON in Run Mode, and OFF in Stop
Mode. The Program LED is ON when
the inverter is in Program Mode, and
OFF for Monitor Mode. All four mode
combinations are possible. The dia-
gram to the right depicts the modes
and the mode transitions via keypad.
Note Some factory automation devices such as PLCs have alternative Run/Pro-
gram modes; the device is in either one mode or the other. In the Omron
inverter, however, Run Mode alternates with Stop Mode, and Program Mode
alternates with Monitor Mode. This arrangement lets you program some value
while the inverter is operating – providing flexibility for maintenance person-
nel.

Choosing a Programming Device

Introduction
Omron variable frequency drives (inverters) use the latest electronics technol-
ogy for getting the right AC waveform to the motor at the right time. The bene-
fits are many, including energy savings and higher machine output or
productivity. The flexibility required to handle a broad range of applications
has required ever more configurable options and parameters - inverter are
now a complex industrial automation component. And this can make a prod-
uct seem difficult to use, but the goal of this chapter is to make this easier for
you.
As the powerup test in 2-4 Powerup Test demonstrated, you do not have to
program very many parameters to run the motor. In fact, most applications
would benefit only from programming just a few, specific parameters. This
chapter will explain the purpose of each set of parameters, and help you
choose the ones that are important to your application.
If you are developing a new application for the inverter and a motor, finding
the right parameters to change is mostly an exercise in optimization. There-
fore, it is okay to begin running the motor with a loosely tuned system. By
making specific, individual changes and observing their effects, you can
achieve a finely tuned system.

Introduction of Inverter Programming
The front panel keypad is the first and best way to get to know the inverter's
capabilities. Every function or programmable parameter is accessible from the
keypad.

Using the Keypad Devices
The MX2 Series inverter front keypad contains all the elements for both moni-
toring and programming parameters. The keypad layout is pictured below. All
other programming devices for the inverter have a similar key arrangement
and function.
3-2-1
Key and Indicator Legend
• Run LED - ON when the inverter output is ON and the motor is develop-
ing torque (Run Mode), and OFF when the inverter output is OFF (Stop
Mode).
• Program LED - This LED is ON when the inverter is ready for parameter
editing (Program Mode). It is OFF when the parameter display is monitor-
ing data (Monitor Mode).
• Run Key Enable LED - This LED is ON when the inverter is ready to
respond to the Run key, OFF when the Run key is disabled.
• Run Key - Press this key to run the motor (the Run Enable LED must be
ON first). Parameter F004, Keypad Run Key Routing, determines whether
the Run key generates a Run FWD or Run REV command.
• Stop/Reset Key - Press this key to stop the motor when it is running
(uses the programmed deceleration rate). This key will also reset an
alarm that has tripped.
• Parameter Display - A 4-digit, 7-segment display for parameters and
function codes.
• Display Units, Hertz/Amperes - One of these LEDs will be ON to indi-
cate the units associated with the parameter display.
• Power LED - This is ON when the power input to the inverter is ON.
• Alarm LED - ON when an inverter trip is active (alarm relay contact will
be closed).
• Cycle Key - This key is used to escape from the current situation.
• Up/Down keys - Use these keys alternatively to move up or down the lists
of parameter and functions shown in the display, and increment/decre-
ment values.
• Set key - This key is used to navigate through the lists of parameters and
functions for setting and monitoring parameter values. When the unit is in
Program Mode and you have edited a parameter value, press the Set key
to write the new value to the EEPROM.

Operational Modes
The RUN and PRG LEDs tell just part
of the story; Run Mode and Program
Modes are independent modes, not
opposite modes. In the state diagram
to the right, Run alternates with Stop,
and Program Mode alternates with
Monitor Mode. This is a very important
ability, for it shows that a technician
can approach a running machine and
change some parameters without shut-
ting down the machine.
The occurrence of a fault during opera-
tion will cause the inverter to enter Trip
Mode as shown. An event such as an
output overload will cause the inverter
to exit the Run Mode and turn OFF its
output to the motor. In the Trip Mode,
any request to run the motor is ignored. You must clear the error by pressing
the Stop/Reset switch. See 6-2 Monitoring Trip Events, History, & Conditions
on page 273.
3-2-3
Run Mode Edit
The inverter can be in Run Mode (inverter output is controlling motor) and still
allow you to edit certain parameters. This is useful in applications that must
run continuously, you need some inverter parameter adjustment.
The parameter tables in this chapter have a column
titled “Run Mode Edit”. An Ex mark means the param-
eter cannot be edited; a Check mark means the
parameter can be edited. The Soft lock selection
(parameter ) determines when the Run Mode
access permission is in effect and access permission in
other conditions, as well. It is the responsibility of the
user to choose a useful and safe software lock setting
for the inverter operating conditions and personnel. Please refer to 3-6-5 Soft-
ware Lock Mode on page 130 for more information.
3-2-4
Control Algorithms
The motor control program in the
MX2 inverter has two sinusoidal
PWM switching algorithms. The
intent is that you select the best
algorithm for the motor and load
characteristics of your application.
Both algorithms generate the fre-
quency output in a unique way. Once
configured, the algorithm is the basis
for other parameter settings as well
(see 3-5-4 Torque Control Algo-
rithms on page 101). Therefore, choose the best algorithm early in your
application design process.

Dual Rate Selection
The MX2 series inverter has Dual Rate, so that it can work in two different
types of load condition, Constant torque application and Variable torque appli-
cation. Select parameter depending on your application.
When changed, the rated output current and related items are changed auto-
matically. Differences between HD and ND are described below.
Initial values of HD and ND are different shown as below table. Be sure to
note that when the dual rate selection b049 is changed those initial values are
also changed except H003/H203. (Even if currently set value is within the
range of both HD and ND, data is initialized when b049 is changed.)
When ND is selected, following parameters are not displayed.

“D” Group: Monitoring Functions
You can access important parameter values with the “D” Group monitoring
functions, whether the inverter is in Run Mode or Stop Mode. After selecting
the function code number for the parameter you want to monitor, press the
Function key once to show the value on the display. In functions and
, the intelligent terminals use individual segments of the display to show
ON/OFF status.
If the inverter display is set to monitor a parameter and powerdown occurs,
the inverter stores the present monitor function setting. For your convenience,
the display automatically returns to the previously monitored parameter upon
the next powerup.
