www.invertekdrives.com 4.3. Protective Earth (PE) Connection Grounding Guidelines The ground terminal of each Optidrive should be individually connected DIRECTLY to the site ground bus bar (through the filter if installed). Optidrive ground connections should not loop from one drive to another, or to, or from any other equipment. Ground loop impedance must confirm to local industrial safety regulations. To meet UL regulations, UL approved ring crimp terminals should be used for all ground wiring connections. The drive Safety Ground must be connected to system ground. Ground impedance must conform to the requirements of national and local industrial safety regulations and/or electrical codes. The integrity of all ground connections should be checked periodically. Protective Earth Conductor The Cross sectional area of the PE Conductor must be at least equal to that of the incoming supply conductor. Safety Ground This is the safety ground for the drive that is required by code. One of these points must be connected to adjacent building steel (girder, joist), a floor ground rod, or bus bar. Grounding points must comply with national and local industrial safety regulations and/ or electrical codes. Motor Ground The motor ground must be connected to one of the ground terminals on the drive. Ground Fault Monitoring As with all inverters, a leakage current to earth can exist. The Optidrive is designed to produce the minimum possible leakage current whilst complying with worldwide standards. The level of current is affected by motor cable length and type, the effective switching frequency, the earth connections used and the type of RFI filter installed. If an ELCB (Earth Leakage Circuit Breaker) is to be used, the following conditions apply: �� A Type B Device must be used. �� The device must be suitable for protecting equipment with a DC component in the leakage current. �� Individual ELCBs should be used for each Optidrive. Shield Termination (Cable Screen) The safety ground terminal provides a grounding point for the motor cable shield. The motor cable shield connected to this terminal (drive end) should also be connected to the motor frame (motor end). Use a shield terminating or EMI clamp to connect the shield to the safety ground terminal. 4.4. Incoming Power Connection 4.4.1. Cable Selection �� For 1 phase supply, the mains power cables should be connected to L1/L, L2/N. �� For 3 phase supplies, the mains power cables should be connected to L1, L2, and L3. Phase sequence is not important. �� For compliance with CE EMC requirements, refer to section 4.10 EMC Compliant Installation on page 14. �� A fixed installation is required according to IEC61800-5-1 with a suitable disconnecting device installed between the Optidrive and the AC Power Source. The disconnecting device must conform to the local safety code / regulations (e.g. within Europe, EN60204-1, Safety of machinery). �� The cables should be dimensioned according to any local codes or regulations. Maximum dimensions are given in section 10.2. Rating Tables. 4.4.2. Fuse / Circuit Breaker Selection �� Suitable fuses to provide wiring protection of the input power cable should be installed in the incoming supply line, according to the data in section 10.2. Rating Tables. The fuses must comply with any local codes or regulations in place. In general, type gG (IEC 60269) or UL type J fuses are suitable; however in some cases type aR fuses may be required. The operating time of the fuses must be below 0.5 seconds. �� Where allowed by local regulations, suitably dimensioned type B MCB circuit breakers of equivalent rating may be utilised in place of fuses, providing that the clearing capacity is sufficient for the installation. �� The maximum permissible short circuit current at the Optidrive Power terminals as defined in IEC60439-1 is 100kA. Power & Control Wiring 4

www.invertekdrives.com 4.4.3. Optional Input Choke �� An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions occur: o The incoming supply impedance is low or the fault level / short circuit current is high. o The supply is prone to dips or brown outs. o An imbalance exists on the supply (3 phase drives). o The power supply to the drive is via a busbar and brush gear system (typically overhead Cranes). �� In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults. Part numbers are shown in the table. Supply Frame Size AC Input Inductor 230 Volt 1 Phase 1 OPT-2-L1016-66 2 OPT-2-L1025-66 400 Volt 3 Phase 1 OPT-2-L3006-66 2 OPT-2-L3010-66 4.5. Motor Connection �� The drive inherently produces fast switching of the output voltage (PWM) to the motor compared to the mains supply. For motors which have been wound for operation with a variable speed drive additional measures are not required; however if the quality of insulation is unknown the motor manufacturer should be consulted and preventative measures may be required. �� The motor should be connected to the Optidrive U, V, and W terminals using a suitable 3 or 4 core cable. Where a 3 core cable is utilised, with the shield operating as an earth conductor, the shield must have a cross sectional area at least equal to the phase conductors when they are made from the same material. Where a 4 core cable is utilised, the earth conductor must be of at least equal cross sectional area and manufactured from the same material as the phase conductors. �� The motor earth must be connected to one of the Optidrive earth terminals. �� Maximum permitted motor cable length for all models: 100 metres shielded, 150 metres unshielded. �� Where multiple motors are connected to a single drive using parallel cables, an output choke must be installed. 4.6. Motor Terminal Box Connections Do not install any mechanical or electro-mechanical switching devices between the drive and motor. Where a local isolator is installed close to the motor, this should be interlocked with the drive control circuit to ensure the drive is disabled when the motor is isolated. Most general purpose motors are wound for operation on dual voltage supplies. This is indicated on the nameplate of the motor. This operational voltage is normally selected when installing the motor by selecting either STAR or DELTA connection. STAR always gives the higher of the two voltage ratings.

www.invertekdrives.com 4.7. Control Terminal Wiring �� All analog signal cables should be suitably shielded. Twisted pair cables are recommended. �� Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other. �� Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable. �� Maximum control terminal tightening torque is 0.5Nm. �� Control Cable entry conductor size: 0.05 – 2.5mm2 / 30 – 12 AWG. 4.8. Using the REV/0/FWD Selector Switch (Switched Version Only) By adjusting the parameter settings the Optidrive can be configured for multiple applications and not just for Forward or Reverse. This could typically be for Hand/Off/Auto applications (also known and Local/Remote) for HVAC and pumping industries. The integrated switch operates in parallel with drive terminal 2 (T2) and terminal 3 (T3) as digital input 1 and digital input 2. By default, the integrated switch is enabled. If required, the built in control switch may be disabled using the following method: 1) Set correct value in P-14 to enable advanced parameter access, e.g. 201 2) Go to “P-00” and make sure drive is in stop condition (not running, not tripped). 3) Press and hold “STOP” button for about 1s, drive will show “Lc-OFF” or “Lc-On” message. 4) Use “UP” or “DOWN” key to select the option: “Lc-OFF” means integrated switches are enabled. “Lc-On” means the switches are locked/disabled. 5) Press the “STOP” button again to exit.

Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the control panel using a suitable EMC clamp or gland, as close to the drive as possible. For IP66 drives, connect the motor cable screen to the internal ground clamp. 6 Compliance with category C1 conducted emissions only is achieved. For compliance with category C1 radiated emissions, additional measures may be required, contact your Sales Partner for further assistance. 7 Permissible cable length with additional external EMC filter. 4.13. Optional Brake Resistor Optidrive E3 Frame Size 2 and above units have a built in Brake Transistor. This allows an external resistor to be connected to the drive to provide improved braking torque in applications that require this. The brake resistor should be connected to the “+” and “BR” terminals as shown in the diagrams in sections 4.2. Connection Diagram. The voltage level at these terminals may exceed 800VDC. Stored charge may be present after disconnecting the mains power. Allow a minimum of 10 minutes discharge after power off before attempting any connection to these terminals. Suitable resistors and guidance on selection can be obtained from your Invertek Sales Partner. The brake transistor is enabled here by setting P-34 > 0. See section 6. Parameters for more information. Power & Control Wiring 4

www.invertekdrives.com 6.3. Parameter Functions The following sections highlight the parameters relevant to certain functions in the drive firmware. Parameters are grouped according to the function. 6.3.1. Basic Functions Motor Nameplate Settings (relevant parameters) Par. Description Minimum Maximum Default Units P-07 Motor Rated Voltage / Back EMF at rated speed (PM / BLDC) 0 250 / 500 230 / 400 V For Induction Motors, this parameter should be set to the rated (nameplate) voltage of the motor (Volts). For Permanent Magnet or Brushless DC Motors, it should be set to the Back EMF at rated speed. P-08 Motor Rated Current Drive Rating Dependent A This parameter should be set to the rated (nameplate) current of the motor. P-09 Motor Rated Frequency 10 500 50 (60) Hz This parameter should be set to the rated (nameplate) frequency of the motor. When commissioning the drive, it is necessary to enter certain information about the motor into the drive to ensure the drive is optimised to control the connected motor and additionally to prevent damage to the motor. For standard induction motors, the parameters are listed below. For alternative motor types, refer to the later relevant sections for each motor type. Working in RPM (relevant parameters) Par. Description Minimum Maximum Default Units P-10 Motor Rated Speed 0 30000 0 RPM This parameter can optionally be set to the rated (nameplate) RPM of the motor. When set to the default value of zero, all speed related parameters are displayed in Hz and the slip compensation (where motor speed is maintained at a constant value regardless of applied load) for the motor is disabled. Entering the value from the motor nameplate enables the slip compensation function, and the Optidrive display will now show motor speed in RPM. All speed related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in RPM. NOTE If P-09 value is changed, P-10 value is reset to 0. Optidrive E3 normally uses frequency for all speed related parameters, e.g. Minimum and Maximum Output Frequency. It is also possible to work directly in RPM, by setting the above parameter to the relevant rated speed from the connected motor nameplate. When set to the default value of zero, all speed related parameters are displayed in Hz, and slip compensation for the motor is disabled. Entering the value from the motor nameplate enables the slip compensation function, and the Optidrive display will also now show motor speed in RPM. All speed related parameters, such as Minimum and Maximum Speed, Preset Speeds etc. will also be displayed in RPM. NOTE If P-09 value is changed, P-10 value is reset to 0. Low Frequency Torque Boost (relevant parameters) Par. Description Minimum Maximum Default Units P-11 Low Frequency Torque Boost 0.0 Drive Dependent % Low frequency torque can be improved by increasing this parameter. Excessive boost levels may however result in high motor current and increased risk of tripping on Over Current or Motor Overload (refer to section 11.1. Fault Code Messages). This parameter operates in conjunction with P-51 (Motor Control Mode) as follows: P-51 P-11 0 0 Boost is automatically calculated according to autotune data. >0 Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2. 1 All Voltage boost = P-11 x P-07.This voltage is applied at 0.0Hz, and linearly reduced until P-09 / 2. 2, 3, 4 All Boost current level = 4*P-11*P-08. For IM motors, when P-51 = 0 or 1, a suitable setting can usually be found by operating the motor under very low or no load conditions at approximately 5Hz, and adjusting P-11 until the motor current is approximately the magnetising current (if known) or in the range shown below. Frame Size 1: 60 – 80% of motor rated current. Frame Size 2: 50 – 60% of motor rated current. Frame Size 3: 40 – 50% of motor rated current. Frame Size 4: 35 – 45% of motor rated current. Parameters 6

www.invertekdrives.com Low Frequency Torque Boost is used to increase the applied motor voltage and hence current at low output frequencies. This can improve low speed and starting torque. Increasing the boost level will increase motor current at low speed, which may result in the motor temperature rising - force ventilation or additional cooling of the motor may then be required. In general, the lower the motor power, the higher the boost setting that may be safely used. For IM motor types (P-51 = 0 or 1), the value entered determines the voltage applied to the motor at 0.0Hz relative to P-07 setting. e.g. �� P-07 = 400V �� P-11 = 2% �� Output voltage applied to the motor at 0.0Hz = 2% x 400V = 8V. This boost voltage is then linearly reduced up to 50% of the motor rated speed (P-09). When operating with alternative motor types (P-51 = 2, 3 or 4) this parameter is used to set an additional boost current which is injected into the motor. The actual current level is defined as 4*P-11*P-08. This additional current is injected between 0.0Hz and 10% of rated frequency.

Asynchronous Induction Motors (IM) Vector Control Optidrive E3 factory default parameters are intended for use with IM motors where the power rating of the motor is approximately the same or slightly less than the indicated power rating of the drive. In this case, it should be possible to operate the motor without any parameter adjustment at all for initial testing. For optimum performance, the drive parameters should be adjusted to match the motor ratings. This will also ensure correct protection of the motor from damage due to overload. The basic parameters that should be adjusted are: �� P-07 : Motor Rated Voltage (V) �� P-08 : Motor Rated Current (A) �� P-09 : Motor Rated Frequency (Hz) In addition, it is also possible to set: �� P-10 : Motor Rated Speed (RPM) When this parameter is adjusted, slip compensation is activated. Slip compensation attempts to compensate the motor speed relative to the load applied, such that when operating at a constant speed with different loads, the motor shaft speed should remain approximately the same. To further improve the performance of the motor, the following additional steps can be followed: �� Carry out an Autotune. o This requires Advanced Parameter Access, P-14 = P-37 + 100 (Default : 201). o After the correct nameplate information is entered from the motor, the drive can additionally measure some electrical characteristics of the motor to further optimise the motor control to suit connected motor. o This is achieved by setting P-52 = 1. Parameters 6

www.invertekdrives.com The autotune will begin IMMEDIATELY following the setting of this parameter! o The drive output will be enabled, and the motor shaft may move. It is important to ensure this is safe before carrying out the autotune. o For IM motors, the autotune takes only a few seconds, and measures only the motor stator resistance. Parameter P-55 will be updated with the new value. �� Adjust the Low Frequency Torque Boost o IM motors require some additional voltage at low frequency to improve the low speed operation and torque. o By adjusting P-11, it is possible to optimise the low speed operation. o If P-11 is increased too far, excessive motor heating or over current trips may result. �� Speed regulation and response to load changes may be improved by adjusting P-11 Vector Gain to suit the motor and connected load. o Higher values will provide a more dynamic behaviour at the risk of instability. Synchronous Permanent Magnet AC Motors (PM), BLDC Motors and LSPM Motors Suitable Motors Optidrive E3 provides open loop control of permanent magnet AC motors including BLDC and LSPM type, intended to allow the use of high efficiency motors in simple applications. Both interior and exterior magnets type motors are supported. Operation is permitted with motors meeting the following criteria: �� The motor Back EMF is >=1 V / Hz. o NOTE Operation of motors with <1V/Hz Back EMF ratio may be possible with reduced speed range. �� Maximum motor frequency 360Hz. �� RMS Back EMF must not exceed the AC supply voltage during motor operation. o Warning! If the peak Back EMF exceeds 800V, the drive may be permanently damaged! Commissioning Procedure When operating with permanent magnet motors, the commissioning steps are as follows: �� Enter the motor Back EMF at Rated Frequency / Speed in parameter P-07. o This parameter must not be set to the rated motor voltage, but the actual Back EMF imposed by the motor magnets at the drive output terminals. o It is sometimes necessary to derive this information from a voltage constant and the rated operating speed, e.g. ���� If a motor has rated speed 2500RPM, back EMF constant 80V / 1000 RPM, P-07 = (2500 * 80) / 1000 = 200V. ���� Alternatively, obtain the value from the motor supplier, or by direct measurement using an oscilloscope. �� Enter the Motor Rated Current in P-08. o It is possible that excessive current levels may permanently damage the motor, therefore this parameter must be set correctly to ensure this cannot occur. o Additionally, this current level is used by the autotune to determine the correct inductance values. �� Enter the motor rated frequency in P-09. �� Optionally enter the motor rated speed in P-10. �� Enabled Advanced Parameter Access by setting P-14 = P-37 + 100 (Default : 201). �� Select the appropriate motor type in P-51 o For PM motor control P-51 = 2 o For BLDC motor control P-51 = 3 o For LSPM motor control P-51 = 5 �� Carry out an Autotune. o An Autotune MUST be carried out. o This is achieved by setting P-52 = 1. o The autotune will begin IMMEDIATELY following the setting of this parameter! The drive output will be enabled, and the motor shaft may move. It is important to ensure this is safe before carrying out the autotune. o For PM motors, the autotune measures the motor stator resistance and both Q and D axis inductance values. Parameters P-55, P-56 and P-57 will be updated following the measurements. �� It should now be possible to operate the motor. Parameters 6

www.invertekdrives.com �� Low speed and starting of the motor may be further optimised by adjusting P-11. o In PM motor control mode, P-11 adjust the additional current injected into the motor at low frequency to help maintain the rotor alignment and ensure reliable starting. �� Speed regulation and response to load changes may be improved by adjusting P-11 Vector Gain to suit the motor and connected load. o Higher values will provide a more dynamic behaviour at the risk of instability. Synchronous Reluctance Motors (SynRM) Suitable Motors Optidrive E3 provides open loop control of synchronous reluctance AC motors, intended to allow the use of high effciency motors in simple applications. Commissioning Procedure When operating with synchronous reluctance motors, the commissioning steps are as follows: �� Enter the motor rated voltage in parameter P-07. �� Enter the Motor Rated Current in P-08. �� Enter the motor rated frequency in P-09. �� Optionally enter the motor rated speed in P-10. �� Enabled Advanced Parameter Access by setting P-14 = P-37 + 100 (Default : 201). �� Select SynRM motor control in by setting P-51 = 4. �� Carry out an Autotune. o For SynRM motor operation, an Autotune MUST be carried out. o This is achieved by setting P-52 = 1. o The autotune will begin IMMEDIATELY following the setting of this parameter! o The drive output will be enabled, and the motor shaft may move. It is important to ensure this is safe before carrying out the autotune. o For SynRM motors, the autotune measures the motor data required for correct operation. �� It should now be possible to operate the motor. �� Low speed and starting of the motor may be further optimised by adjusting P-11. o In SynRM motor control mode, P-11 adjust the additional current injected into the motor at low frequency to help maintain the rotor alignment and ensure reliable starting. �� Speed regulation and response to load changes may be improved by adjusting P-11 or P-53 to suit the motor and connected load. o Higher values will provide a more dynamic behaviour at the risk of instability.

There are two key parameters which determine the input functions and drive behaviour: P-12 Selects the main drive control source and determines how the output frequency of the drive is primarily controlled. P-15 Assigns the Macro function to the analog and digital inputs. Additional parameters can then be used to further adapt the settings, e.g. P-16 Used to select the format of the analog signal to be connected to analog input 1, e.g. 0 – 10 Volt, 4 – 20mA. P-30 Determines whether the drive should automatically start following a power on if the Enable Input is present. P-31 When Keypad Mode is selected, determines at what output frequency / speed the drive should start following the enable command, and also whether the keypad start key must be pressed or if the Enable input alone should start the drive. P-47 Used to select the format of the analog signal to be connected to analog input 2, e.g. 0 – 10 Volt, 4 – 20mA. 7.2.

Fire Mode The Fire Mode function is designed to ensure continuous operation of the drive in emergency conditions until the drive is no longer capable of sustaining operation. The Fire Mode input may be a normally open (Close to Activate Fire Mode) or Normally Closed (Open to Activate Fire Mode) according to the setting of P-30 Index 2. In addition, the input may be momentary or maintained type, selected by P-30 Index 3. This input may be linked to a fire control system to allow maintained operation in emergency conditions, e.g. to clear smoke or maintain air quality within that building. The fire mode function is enabled when P-15 = 15, 16, 17 or 18, with Digital Input 3 assigned to activate fire mode. Fire Mode disables the following protection features in the drive: O-t (Heat-sink Over-Temperature), U-t (Drive Under Temperature), Th-FLt (Faulty Thermistor on Heat-sink), E-trip (External Trip), 4-20 F (4-20mA fault), Ph-Ib (Phase Imbalance), P-Loss (Input Phase Loss Trip), SC-trp (Communications Loss Trip), I.t-trp (Accumulated overload Trip). The following faults will result in a drive trip, auto reset and restart: O-Volt (Over Voltage on DC Bus), U-Volt (Under Voltage on DC Bus), h O-I (Fast Over-current Trip), O-I (Instantaneous over current on drive output), Out-F (Drive output fault, Output stage trip).

www.invertekdrives.com 9. CAN Communication 9.1. CAN Communication The CAN communication profile in the Optidrive E3 is implemented according to the specification DS301 version 4.02 of CAN in automation (www.can-cia.de). Specific device profiles such as DS402 are not supported. The CAN communication function is enabled by default after power up. However in order to use any control functions through CAN, the following setting is required: P-12 = 7 or 8. The CAN communication baud rate can be set by using parameter P-36 (Index 2). Available baud rates are: 125kbps, 250kbps, 500kbps, 1Mbps. (with default setting as 500kbps). The Node ID is set up through drive address parameter P-36 (Index 1) with the default value of 1. The tables below show the Index and Sub Index required to address each parameter. All User Adjustable parameters are accessible by CAN, except those that would directly affect the communications. All parameter values can be read from the drive and written to, depending on the operating mode of the drive – some parameters may not be changed whilst the drive is enabled for example. Optidrive E3 provides the following default COB-ID and functions: Type COB-ID Function NMT 000h Network management. Sync 080h Synchronous message. COB-ID can be configured to other value. Emergency 080h + Node address Emergency message. PDO1 (TX) 180h + Node address Process data object. PDO1 is pre-mapped and enabled by default. COB-ID can be configured to other value. PDO2 is pre-mapped and disabled by default. Transmission mode, COB-ID and mapping can be configured. PDO1 (RX) 200h + Node address PDO2 (TX) 280h + Node address PDO2 (RX) 300h + Node address SDO (TX) 580h + Node address SDO channel can be used for drive parameter access. SDO (RX) 600h + Node address Error Control 700h + Node address Guarding and Heartbeat function are supported. COB-ID can be configured to other value. NOTE �The Optidrive E3 SDO channel only supports expedited transmission. �� The Optidrive E3 can only support up to 2 Process Data Objects (PDO). All PDOs are pre-mapped; however PDO2 is disabled by default. The table below gives the default PDO mapping information. �� Customer configuration (mapping) will NOT be saved during power down. This means that the CANopen configuration will restore to its default condition each time the drive is powered up. CAN Communication 9

For RX PDO, the following modes are supported: Transmission Type Mode Description 0 – 240 Synchronous The received data will be transferred to the drive active control register when the next sync message is received. 254, 255 Asynchronous The received data will be transferred to the drive active control register immediately without delay. For TX PDO, the following modes are supported: Transmission Type Mode Description 0 Acyclic synchronous TX PDO will only be sent out if the PDO data has changed and PDO will be transmitted on reception of SYNC object. 1-240 Cyclic synchronous TX PDO will be transmitted synchronously and cyclically. The transmission type indicates the number of SYNC object that are. 254 Asynchronous TX PDO will only be transferred once corresponding RX PDO has been received. 255 Asynchronous TX PDO will only be transferred anytime if PDO data value has changed. 9.1.3 CAN Open Specific Object Table Index Sub Index Function Access Type PDO Map Default Value 1000h 0 Device Type R U32 N 0 1001h 0 Error Register R U8 N 0 1002h 0 Manufacturer Status Register R U16 N 0 1005h 0 COB-ID Sync RW U32 N 00000080h 1008h 0 Manufacturer Device Name R String N ODE3 1009h 0 Manufacturer Hardware Version R String N x.xx 100Ah 0 Manufacturer Software Version R String N x.xx 100Ch 0 Guard Time (1ms) RW U16 N 0 100Dh 0 Life Time Factor RW U8 N 0 CAN Communication 9

Additional Information Relating to CAN or Modbus or Both 9.2.1 Drive Control Word Format 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 High byte Low byte Bit 0: Run/Stop command: Set to 1 to enable the drive. Set to 0 to stop the drive. Bit 1: Fast stop request. Set to 1 to enable drive to stop with 2nd deceleration ramp. Bit 2: Reset request. Set to 1 in order to reset the drive if drive is under trip condition. User must clear this bit when drive is under normal condition to prevent un-expected reset. Bit 3: Coast stop request. Set to 1 to issue a coast stop command. For normal operation, Bit 3 has the highest priority, bit 0 has the lowest priority (bit 3>bit 1>bit 0). For example if user set command as 0x0009, drive will do a coast stop rather than run. For normal run/start, just set this register to 1. NOTE Start/stop (bit 0), fast stop (bit 1) and coast stop (bit 3) only works if P-31= 0 or 1. Otherwise, start/stop function is controlled by drive control terminals. Reset function (bit 2) works all the time as long as drive is operated under Modbus control mode (P-12=3 or 4). 9.2.2 Speed Reference Format Speed reference value is transferred with one decimal place (200 = 20.0Hz). The maximum speed reference value is limited by P-01. Either register 2 or register 5 can be used for speed reference control, however only one reference should be used in any control system, otherwise unexpected behaviour can result. 9.2.3 Acceleration / Deceleration Ramp Time Active only when P-12 = 4, this register specifies the drive acceleration and deceleration ramp time. The same value is applied simultaneously to the acceleration and deceleration ramp times. The value has two decimal places, e.g. 500 = 5.00 seconds. 9.2.4 Drive status and error code Word High byte gives drive error code. (Valid when the drive is tripped, see 0 for further details) Low byte gives drive status information as follows: Bit 0: 0 =Drive Stopped, 1 = Drive Running Bit 1: 0 = OK, 1 = Drive Tripped Bit 5: 0 = OK, 1 = In Standby Mode Bit 6: 0 = Not Ready, 1 = Drive Ready to Run (not tripped, hardware enabled and no mains loss condition) CAN Communication 9

www.invertekdrives.com Technical Data 10 10.4. Additional Information for UL Compliance Optidrive E3 is designed to meet the UL requirements. For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333. In order to ensure full compliance, the following must be fully observed. Input Power Supply Requirements Supply Voltage 200 – 240 RMS Volts for 230 Volt rated units, + /- 10% variation allowed. 240 Volt RMS Maximum. 380 – 480 Volts for 400 Volt rated units, + / - 10% variation allowed, Maximum 500 Volts RMS. Imbalance Maximum 3% voltage variation between phase – phase voltages allowed. All Optidrive E3 units have phase imbalance monitoring. A phase imbalance of > 3% will result in the drive tripping. For input supplies which have supply imbalance greater than 3% (typically the Indian sub-continent & parts of Asia Pacific including China) Invertek Drives recommends the installation of input line reactors. Frequency 50 – 60Hz + / - 5% Variation Short Circuit Capacity Voltage Rating Min kW (HP) Max kW (HP) Maximum supply short-circuit current 115V 0.37 (0.5) 1.1 (1.5) 100kA rms (AC) 230V 0.37 (0.5) 11 (15) 100kA rms (AC) 400 / 460V 0.75 (1) 22 (30) 100kA rms (AC) All the drives in the above table are suitable for use on a circuit capable of delivering not more than the above specified maximum short-circuit Amperes symmetrical with the specified maximum supply voltage when protected by Class J fuses. Mechanical Installation Requirements All Optidrive E3 units are intended for indoor installation within controlled environments which meet the condition limits shown in section 10.1. Environmental. The drive can be operated within an ambient temperature range as stated in section 10.1. Environmental. For IP66 (Nema 4X) units, installation in a pollution degree 2 environment is permissible. Electrical Installation Requirements Incoming power supply connection must be according to section 4.4. Incoming Power Connection. Suitable Power and motor cables should be selected according to the data shown in section 10.2. Rating Tables and the National Electrical Code or other applicable local codes. Motor Cable 75°C Copper must be used. Power cable connections and tightening torques are shown in section 3.3. Mechanical Dimensions – IP66 (Nema 4X) Enclosed Units. Integral Solid Sate short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the national electrical code and any additional local codes. Ratings are shown in section 10.2. Rating Tables. Transient surge suppression must be installed on the line side of this equipment and shall be rated 480Volt (phase to ground), 480 Volt (phase to phase), suitable for over voltage category iii and shall provide protection for a rated impulse withstand voltage peak of 4kV. UL Listed ring terminals / lugs must be used for all bus bar and grounding connections. General Requirements Optidrive E3 provides motor overload protection in accordance with the National Electrical Code (US). • Where a motor thermistor is not fitted, or not utilised, Thermal Overload Memory Retention must be enabled by setting P-50 = 1. • Where a motor thermistor is fitted and connected to the drive, connection must be carried out according to the information shown in section 4.11.2. Motor Thermistor Connection. 10.5. EMC Filter Disconnect Drives with an EMC filter have an inherently higher leakage current to Ground (Earth). For applications where tripping occurs the EMC filter can be disconnected (on IP20 units only) by completely removing the EMC screw on the side of the product. Remove the screw as indicated right. The Optidrive product range has input supply voltage surge suppression components fitted to protect the drive from line voltage transients, typically originating from lightning strikes or switching of high power equipment on the same supply. When carrying out a HiPot (Flash) test on an installation in which the drive is built, the voltage surge suppression components may cause the test to fail. To accommodate this type of system HiPot test, the voltage surge suppression components can be disconnected by removing the VAR screw After completing the HiPot test, the screw should be replaced and the HiPot test repeated. The test should then fail, indicating that the voltage surge suppression components are once again in circuit. L1 L3 EMC L2/N U V W 1 2 3 4 5 6 7 8 9 10 11 I0I0I I0I0I

www.invertekdrives.com 11.2 Resetting a Fault When the drive trips, and a fault message is displayed, it can be reset in one of the following ways: �Completely remove the incoming power supply, and allow the power to power off completely. Re-apply the power. �Remove and reapply the enable input. �Press the stop / Reset button. �If Modbus or CAN are in use, set the reset bit in the control word from 0 to 1. In the event of O-I, hO-I or I.t-trp faults, in order to prevent damage that may occur through repeatedly enabling the drive into a fault condition, these trips cannot be reset immediately. A delay time according to the following table must be allowed before reset is possible. First Trip 2 seconds delay before reset is possible Second Trip 4 seconds delay before reset is possible Third Trip 8 seconds delay before reset is possible Fourth Trip 16 seconds delay before reset is possible Fifth Trip 32 seconds delay before reset is possible Subsequent Trips 64 seconds delay before reset is possible Troubleshooting 11
