conductive pollution which can become conductive due to condensation, etc. Otherwise, problems such as tracking phenomena may damage parts, resulting in fire. When wiring the power for this device, be sure to mount a shutoff switch for the main power to this unit within reach of the operator. In addition, when wiring the power for AC power models, install a time-lag (T) fuse (rated current 0.2 A, rated voltage 250 V) as specified by IEC 127. Otherwise, tracking phenomena or parts failure due to other factors may cause fire. Do not disassemble this device. Doing so might cause electric shock or faulty operation. Before removing, mounting, or wiring this device, be sure to turn off the power to the device and all connected devices. Failure to do so might cause electric shock. Do not touch electrically charged parts such as the power terminals. Doing so might cause electric shock. CAUTION Use this device within the operating ranges recommended in the specifications (temperature, humidity, voltage, vibration, shock, mounting direction, atmosphere, etc.). Do not block ventilation holes. Doing so might cause fire or faulty operation. Wire this device properly according to predetermined standards. Also wire the device using specified power leads according to recognized installation methods. Failure to do so might cause electric shock, fire or faulty operation. Do not allow lead clippings, metal shavings or water to enter the controller case. Doing so might cause fire or faulty operation. Firmly tighten the terminal screws at the torque listed in the specifications. Insufficient tightening of terminal screws might cause electric shock or fire. Do not use unused terminals on this device as relay terminals. Doing so might cause electric shock, fire, or faulty operation. We recommend attaching the terminal cover (sold separately) after wiring this device. Failure to do so might cause electric shock, fire, or faulty operation. Use the relays within the recommended life. Failure to do so might cause fire or faulty operation. If there is a risk of a power surge caused by lightning, use a surge absorber (surge protector) to prevent fire or device failure. Do not make incorrect connections. If the cables are connected incorrectly, this might cause the unit to malfunction. The controller does not function for approximately 6 s. after the power has been turned ON. Great care should be taken if the relayoutput from the controller is used as an interlock signal.

isolator. Do not connect multiple loader cables to multiple units from one personal computer. The current coming from other circuits might cause an error in the indication of the PV. When wiring RS-485 communications, do not connect a terminating resistor to either end of the communication path. A terminating resistor might cause a communication failure. Do not operate the keys with a mechanical pencil or other sharp-tipped object. Doing so might cause faulty operation. In addition to ON/OFF control and conventional PID control, this unit is equipped with self- tuning control, which does not require manual setting of control constants. Self-tuning control ensures stable control even after a change in the SP or an external disturbance. This is achieved by monitoring the control target, learning its characteristics, and automatically calculating control constants.

1 Start from the opera- tion display (if nec- essary press [mode] once to get the op- eration display). If the sensor has not been wired or is discon- nected, an alarm for abnormal PV input (any one from AL0 1 to AL 1 1) may appear on the upper display. 2 Press and hold [para] for more than 2s to get the parameter setup display. a--M is shown on the upper display. In case of ON/OFF con- trol, r--r appears on the upper display. 3 Press and hold [para] for more than 2s again to get the setup setting display. The current set value for C0 1 (PV input range type) is displayed. 4 When the [<], [ ] or [ ] key is pressed, the rightmost digit on the lower dis- play flashes. If no key is pressed for more than 2s after changing to the desired value in the PV input range list, the display changes from flashing to continuously lit, and the displayed value is now set. Setup of event operation type In this example, the event 1 operation type is set to deviation high limit. 1 Start from the opera- tion display (if nec- essary press [mode] once to get the op- eration display). 2 Press and hold [para] for more than 2s to get the parameter setup display. a--M is shown on the upper display. 3 Press and hold [para] for more than 2s again to get the setup setting display. The current set value for C0 1 (PV input range type) is displayed. 4 Press [para] repeat- edly to get e 1.c 1 on the upper display. 0 is displayed on the lower display. 0 on the lower display indicates that the event operation type is set to "none." 5 When the [ ] or [ ] key is pressed, the rightmost digit on the lower display flashes. Change the flashing digit to 4 by pressing [ ] or [ ]. If no key is pressed for more than 2s, the displayed value is set and the display changes from flashing to continu- ously lit. 4 on the lower display indicates that the event operation type is set for deviation high limit. Similarly, use e2.C 1 to set the event 2 operation type, and use e3.C 1 for event 3. Red letters : Items before operation Blue letters : Items during operation Execution of auto tuning (AT) AT forces ON/OFF of the MV a number of times (a limit cycle) to calculate PID values. Check that this operation does not create any problems for the as- sociated equipment before executing AT. 1 Start from the opera- tion display (if nec- essary press [mode] once to get the op- eration display). 2 Press and hold [para] for more than 2s to get the parameter setup display. a--M is shown on the upper display. 3 Press [para] twice. The upper display says at and the lower display says at.Of. If the control method is ON/OFF control and if Bit 3 (AT stop/start display) of the mode display setup (C73) is set to "disabled: 0," nothing is displayed. 4 When [ ] or [ ] is pressed, at.Of flashes. Flashing occurs only in RUN and AUTO modes, if there is no PV input abnormality. Also, if "AT stop/start" is selected for DI assign- ment, the display does not blink and no change can be made. 5 [Press [ ] once. The lower display starts to flash at.On. 6 If no key is pressed for more than 2s, at.ON remains steadily lit and AT begins. During AT, the rightmost decimal point flashes twice repeatedly. (When AT is done, the light goes off and the new PID values go into effect.) During the AT process, if the mode is changed to READY or MANUAL, if PV input is faulty, or if a power failure occurs, AT stops automatically without changing the PID values. AT can also be stopped by changing the setting from At.ON to At.OF (return to step 3 above). Setup of SP value 1 Start from the opera- tion display (if nec- essary press [mode] once to get the op- eration display). 2 Check that the operation display is displaying the SP. (If not, press [para] repeatedly until the SP is displayed.) 3 When the [<], [ ] or [ ] key is pressed, the rightmost digit on the lower display flashes and the SP can be changed to the desired value. In this case, the flash- ing of the numerical value implies that it is not yet set. A nu- merical setting that is being changed flashes the same way. If an SP limit is in effect, the numerical value cannot be changed to a value above the limit. The SP limit must be changed first. 4 If no key is pressed for more than 2s, the displayed value is set and the display changes from flash- ing to continuously lit. If the [mode] key is pressed when the display is flashing, the status returns to that of step 1.

• If the key lock is set, the numerical value does not flash, and the value cannot be changed. To change a numerical value, cancel the key lock first. RUN/READY mode selection 1 Start from the opera- tion display (if neces- sary press [mode] once to get the op- eration display). 2 Press and hold [para] for more than 2s to get the parameter setup display. a--M is shown on the upper display. In case of ON/OFF con- trol, r--r appears on the upper display. 3 Press the [para] key once. The upper dis- play says r--r and the lower display says rdy (or run). The current mode is in- dicated by run for RUN mode or rdy for READY mode. 4 When [ ] or [ ] is pressed, the lower display flashes. If the DI assignment is set to "RUN/READY se- lection," the display does not flash and no change can be made. 5 When [ ] or [ ] is pressed, run (or rdy) on the lower display flashes. 6 If no key is pressed for more than 2s, the displayed value is set and the display changes from flash- ing to continuously lit. Setup of PID value 1 Start from the opera- tion display (if neces- sary press [mode] once to get the op- eration display). 2 Press and hold [para] for more than 2s to get the parameter setup display. a--M is shown on the upper display. 3 Press [para] repeat- edly to get p-1 (for proportional band) on the upper display. The value set for p-1 is displayed on the lower display. If the control method is "ON/OFF control," noth- ing is displayed. 4 When [<], [ ] or [ ] is pressed, the right- most digit on the lower display flashes, and can be changed to the desired value for the proportional band. In this case, the flash- ing of the numerical value implies that it is not yet set. A nu- merical setting that is being changed flashes the same way. The proportional band can be set in a range from 0.1 to 999.9%. 5 If no key is pressed for more than 2s, the displayed value is set and the display changes from flashing to continuously lit. If the [mode] key is pressed when the display is flashing, the status re- turns to that of step 1. Similarly, use i-1 to set the integral time (0 to 9999s), and d-1 to set the derivative time (0 to 9999s). Setup of event value 1 Start from the opera- tion display (if neces- sary press [mode] once to get the op- eration display). 2 Press and hold [para] for more than 2s to get the param- eter setup display. a--M is shown on the upper display. 3 Press [para] repeat- edly to get e 1 on the upper display. The lower display says 0. 0 on the lower display indicates that the event main set value is "zero." 4 When [<], [ ] or [ ] is pressed, the rightmost digit on the lower display flashes, and can be changed to the de- sired value for the event. In this case, the flashing of the numerical value implies that it is not yet set. A numerical set- ting that is being changed flashes the same way. 5 If no key is pressed for more than 2s, the displayed value is set and the display changes from flashing to continu- ously lit. If the [mode] key is pressed when the display is flashing, the status returns to that of step 1. Similarly, use e2 to set a value for event 2, and e3 to set a value for event 3. 6 To set hysteresis as well, press [para] once (or twice, depending on the settings) to display e 1.hy on the upper display. The lower display says 5. 5 on the lower display indicates that the cur- rent set value for event hysteresis is 5. 7 When [<], [ ] or [ ] is pressed, the rightmost digit on the lower display flashes, and can be changed to the desired value for hysteresis. If no key is pressed for more than 2s, the displayed value is set and the dis- play changes from flashing to continu- ously lit. Similarly, use e2.hy to set a hysteresis value for event 2, and e3.hy to set a hysteresis value for event 3. Memo

However, when the heat/cool dead zone (C28) is less than 0.0 %, the energy saving effect cannot be obtained. • How the relationship between the output (heat) and output (cool) is made for the PID control result (MV) is set. Note � z Heat/cool output  Formulas and limits for the heat/cool MV “Dead zone” in the explanation below refers to a heat/cool control dead zone. The cool MV and the heat MV are determined by the following formulas and the MV high and low limits. Heat MV = (MV – heat/cool control change point – 0.5 × deadband) × change rate Cool MV = (heat/cool control change point – MV – 0.5 × deadband) × change rate Change rate = 100 Heat/cool control change point - 0.5 × deadband However, MV high and low limits, output low limit (cooling), and output high limit (cooling) are related to the heat MV and cool MV as follows.

Item (Bank) Display Contents Initial value User level MV low limit at AT (Parameter bank) -10.0 to +110.0 % 0.0 % Simple, Standard, High function MV high limit at AT (Parameter bank) -10.0 to +110.0 % 100.0 % AT type (Extended tuning bank) 0: Normal (Standard control characteristics) 1: Immediate response (Control characteristics that respond immediately to external disturbance.) 2: Stable (Control characteristics having less up/down fluctuation of PV) 1 AT Proportional band adjust (Extended tuning bank) 0.00 to 99.99 1.00 High function AT Integral time adjust (Extended tuning bank) 0.00 to 99.99 1.00 AT Derivative time adjust (Extended tuning bank) 0.00 to 99.99 1.00 • When the control method is other than the ON/OFF control (CtrL ≠ 0), the display and setting can be made. • The MV (manipulated variable) during execution of AT can be limited by the MV low limit at AT (At.OL) and MV high limit at AT (AT.OH). When the Heat/Cool control is not used, the MV becomes a value limited by both the MV low limit at AT (At.OL)/MV high limit at AT (At.OH) and MV low limit (OL- 1)/MV high limit (OH- 1) of the PID constant. When the Heat/Cool control is used, the MV becomes a value limited by the MV low limit at AT (At.OL)/MV high limit at AT (At.OH), the heat MV becomes a value limited by the MV low limit (OL- 1)/MV high limit (OH- 1) of the PID constant, and the cool MV becomes a value limited by the output low limit (Cool) (OL 1.C)/output high limit (Cool) (OH 1.C) of the PID constant. • The AT type (At.ty) is a setting item that the PID constant of the control characteristics suitable for the system is calculated by the AT. Set value 1 (immediate response) is adjusted to the process that the heater heating directly affects the PV to aim at the adjustment considering the immediate response. Set value 2 (stability) is adjusted to the process that the heater heating indirectly affects the PV to aim at the adjustment considering the stability. Note When compared to the AT functions of Azbil Corporation's conventional models, set value 1 (immediate response) is close to the SDC10 and set value 0 (normal) is close to the SDC20/21.

The following Figure shows the conceptual diagram expressing differences in control result using the PID constant calculated by each AT type: PV Time Diference in PV change when SP is changed. SP AT type = 1 (Immediate response) AT type = 0 (Normal) AT type = 2 (Stable) • For the AT Proportional band adjust (At-P), AT Integral time adjust (At-I), and AT Derivative time adjust (At-d), the value that the PID constant calculated by the AT is multiplied by each coefficient is written into the set value of the PID constant. However, the coefficient must be a value in the PID constant setting range. Note • Setting that the AT is activated for only the heat PID constant in the Heat/ Co ol control: 50.0 %

When this coefficient is “1” or more, the effect of the overshoot limit/restraint/ control becomes larger as the coefficient becomes larger. • Function of Just-FiTTER settling band (JF.bd) If the deviation (plus or minus) is a larger percentage of the PV range than the preset value, Just-FiTTER starts. If the deviation is a smaller percentage, ST judges that the step response has settled. � � RationaLOOP This RationaLOOP function suppresses the unstable trend if the immediate response to external disturbance is increased by the high precision control logic.

The setting shown below is available for it. Item (Bank) Display Contents Initial value User level SP lag time (Extended tuning bank) 0.0 to 999.9 (No effect when set at “0.0”.) 0.0 High function • When the control method is other than the ON/OFF control (CtrL ≠ 0), the display and setting can be made. • Function of SP lag time (SP.LG) When the SP lag time is set at "0.0", the SP lag function becomes invalid. When this value is "0.1" or more, changes in MV when the SP is changed become smaller and the effect of the overshoot suppression becomes larger as the value becomes larger.

The AT (auto tuning) function is used in the following cases: • The PID constants are set automatically with the control method set at “Fixed PID” ([CtrL = 1]). • The PV rise is slow or overshoot is large in the control with the PID constants, which have been set automatically using the ST function. • The PV rise becomes slow or overshoot becomes large with the control method set at ST ([CtrL] = 2). The AT function can be used when the control method is set at either “Fixed PID” ([CtrL] = 1) or ST ([CtrL = 2]). � � Starting procedures (1) Make sure that the PV input or operation end (heater power, etc.) is controllable. (2) Make sure that the mode indicator [rdy] is off and the operation is in the RUN mode. If the indicator [rdy] is lit and the operation is in the READY mode, change the mode to the RUN mode. (3) Make sure that the mode indicator [man] is off and the operation is in the AUTO mode. If the indicator [man] is lit and the operation is in the MANUAL mode, change the mode to the AUTO mode. (4) Set the parameter setting [AT Stop/Start] to “AT start ([At] = [At.On])”. � � Stopping procedures The AT function is completed automatically. To stop the AT function, which is running, change the parameter setting [AT Stop/Start] to AT stop ([At] = [At.OF]). Additionally, the AT function is stopped when changing the READY mode to the MANUAL mode. � z Display during execution of AT rdy man ev1 ev2 ev3 ot1 ot2 para mode pv sp LED The decimal point at the 1st digit of the upper display (right end digit) flashes twice repeatedly while the AT function is running. When the AT function is completed and the PID constants are changed, this LED goes off. � z Operation during execution of AT The AT function calculates the PID constants using the limit cycle. (1) When the AT function is started, a point, where the SP and PV deviations are split to “2:1”, is determined as ON/OFF change point of the MV (manipulated variable). (2) When the limit cycle is judged as stable, the PID constants are changed and the AT function is completed. 5 - 4 AT (auto tuning) Function

PV SP 2/3 1/3 Insufcient stability AT start Time Normal end Stable cycle In the Heat/Cool control, the AT function is run in the status that both the heat MV and cool MV are operated. In the first half, the MV is changed to the MV low limit/MV high limit. In the latter half, the MV is changed in a slightly narrow range. The following Figure shows an example of the AT execution when the Heat/Cool control deadband is 0.0 %, Heat/Cool control change point is 50.0 %, MV low limit is 0.0 %, and MV high limit is 100.0 %: MV (%) 100.0 Time 50.0 0.0 Heat MV (%) 100.0 Time 50.0 0.0 Cool MV (%) 100.0 Time 50.0 0.0 PV Time SP change point AT is running. Handling Precautions • Before starting the AT function, put the PV input and/or operation end (heater power, etc.) in the controllable status. • When the control method is set at “ON/OFF control” ([CtrL] = 0), the AT function cannot be started. To operate the AT function, set the control method to “Fixed PID” ([CtrL] = 1) or “ST” ([CtrL] = 2). • To start the AT, it is absolutely necessary that the operation is in the READY mode and AUTO mode, and no PV input errors occur. • If the mode is changed to the READY mode or MANUAL mode or if the PV input error or power failure occurs during execution of the AT function, the AT function is stopped without changing of the PID constants.

• When the Heat/Cool control is not used, the MV becomes a value limited by both ranges, one range is between the MV low limit at AT (AT.OL) and MV high limit at AT (AT.OH), and the other is between the MV low limit (OL-1) and MV high limit (OH-1) of the PID constant. When there are no common portions in two ranges, the AT function is stopped automatically. • When the Heat/Cool control is used, the MV becomes a value limited by the MV low limit at AT (At.OL)/MV high limit at AT (At.OH), the heat MV becomes a value limited by the MV low limit (OL-1)/MV high limit (OH- 1) of the PID constant, and the cool MV becomes a value limited by the output low limit (Cool) (OL.1C)/output high limit (Cool) (OH.1C) of the PID constant. • When the MV low limit at AT (At.OL)/high limit (At.OH), MV low limit (OL- 1)/high limit (OH-1), cool-side MV low limit (OL.1C)/cool-side MV high limit (OH.1C) of the PID constant are set unevenly, the PV may not be changed up or down even though the MV is changed by the AT. In this case, the AT is kept continued. If this occurs, the AT is stopped manually, the high limit and low limit of the manipulated variable are set again, and the AT is started again. • The number of limit cycles and period of time from the AT start to AT end may vary depending on the control subject. • The MV ON and OFF are repeated several times during execution of the AT function to perform the limit cycle. (The OFF operation described here means MV limited by the MV low limit at AT ([At.OL]) or MV high limit at AT ([OL]). The default setting before shipment is “0 %”. Additionally, the ON operation described here means MV limited by the MV high limit at AT ([At.OH]) or MV high limit at AT ([OH]). The default setting before shipment is “100 %”. If this AT operation does not function correctly, take any of the following measures: (1) Change the MV low limit at AT ([At.OL]) or MV high limit at AT ([At. Oh]) to an appropriate value, and then start the AT function. (2) Use the ST function. (3) Set the PID constants manually without use of AT. • The AT progress value can be seen in the operation display mode. 6 - 1 List of Operation Displays (p. 6-1) When the Heat/Cool control is not used, the AT progress value decrements from [4] during execution of the AT function and becomes [0] at completion of the AT function. When the Heat/Cool control is used, the AT progress value decrements from [8] during execution of the AT function and becomes [0] at completion of the AT function. In both cases, the AT progress value may be “1” or “0” when the AT process is in the transient status. • Appropriate PID constants cannot be obtained depending on the control subject. If this happens, set the PID constants manually. • The MV ON/OFF change point determined when the AT function is started does not change even though the SP is changed while the AT is running. AT Stop/Start (p. 5-8) and AT (p. 5-18)

When the control method (CtrL) is set to "2" (ST (Self-tuning)), if the following conditions for ST startup are met, ST starts automatically and changes the PID constants. (1) Startup due to change of SP If the SP is changed in RUN mode, ST starts. However, if the amount of SP change is small or if the difference between the SP and PV is small, ST does not start. (2) Startup due to large deviation If the difference between the SP and PV is large while executing control in RUN mode, ST starts. If the difference between the SP and PV is large when READY mode is changed to RUN, ST starts. If the difference between the SP and PV is large when control execution begins in RUN mode after the power has been turned on, ST starts. Handling Precautions • For ST to start, it is essential that the integral time and derivative time of the PID constants be other than "0" ([ I- 1] ≠ 0, [d- 1] ≠ 0). • For ST to start, RUN and AUTO modes must be selected. • Set "High function" to configure the reference values used to judge the amount of SP change or to decide whether the difference between the SP and PV is large or small. However, for most control targets the default settings can be used. • For heat/cool control, ST cannot be used. � � How to start ST (1) Make sure that the PV input and the actuators (heater power, etc.) are ready for control. (2) Make sure that the mode indicator [rdy] is off, indicating RUN mode. If [rdy] is lit, indicating READY mode, change the mode to RUN. (3) Make sure that the [man] mode light is off, indicating AUTO mode. If [man] is lit, indicating MANUAL mode, change the mode to AUTO. (4) Set the control method (CtrL) to "2" (ST (Self-tuning)) in the parameter setup bank. This operation is not needed from the 2nd time on. (5) Set the SP. If ST does not start because the PV is close to the SP (PV≈SP), change the SP so that it is greatly different from the PV. 5 - 5 ST (Self-tuning) Function

� � How to stop ST ST stops automatically. If it is necessary to stop the ST while it is running or to disable ST, set the control method to "Fixed PID" (CtrL = 1) in the parameter setup bank. Also, ST can be stopped by switching to READY or MANUAL mode. � z Display while ST is running While ST is running, the rightmost decimal point LED on the upper display flashes. When ST ends and the PID constants have been changed, this LED turns off. rdy man ev1 ev2 ev3 ot1 ot2 para mode pv sp LED

When using ST, follow the rules shown below. z Before starting ST, make the PV input and the actuators (heater power, etc.) ready for control. z Before starting ST, set PID constants that are capable of adequate PID control. • By default, the proportional band [ P- 1 ] = 5.0 %, integral time [  I- 1 ] = 120 s, and derivative time [ d- 1 ] = 30 s. With the above settings, adequate PID control is possible for most control targets. • If the integral time [  I- 1 ] = 0 s, ST will not start. • If the derivative time [ d- 1 ] = 0 s, ST will not start. z To stop control execution while the controller is turned on, change RUN mode to READY, and then turn off the actuator (heater). To resume control execution, turn on the actuator (heater), and then change READY mode to RUN. z If the ST step execution resolution band (ST.SA) is small, even if ST is executed, the PID constants may not be adjusted. For this reason, specify an appropriately large value for the ST step execution resolution band (ST.SA). Handling Precautions • If the above rules are not observed, the PID constants may change to unsuitable values when ST is complete, resulting in poor control. • While ST is running (the LED will be flashing), if the power to the controller is turned off, the PID constants will not be changed. Also, if the power is turned off just before ST finishes, unsuitable PID constants may be set. If the PID constants are unsuitable, the following methods can be used to correct them. (1) Restore the default PID constants Configure as follows: proportional band [ P- 1 ] = 5.0 %, integral time [  I- 1 ] = 120 s, and derivative time [ d- 1 ] = 30 s. (2) Start ST. Or, set the PID constants using AT, and then start ST. � z If control targets interfere with each other If the control targets are located side by side or one above the other, temperature changes in one may affect ST in the other, resulting in slow control response. In this case, set the control method to “Fixed PID” ([CtrL] = 1). � z If the control target is disturbed intermittently In a case like heat sealing by a packing machine, intermittent temperature drops may affect ST. In this case, set the control method to “Fixed PID” ([CtrL] = 1) � z If PV alarm and reset recur frequently While ST is running, if PV alarms and resets are repeated frequently, they may be interpreted as hunting, resulting in changes of the PID parameters. If these circumstances arise during instrumentation, etc., put the unit into READY mode or disable ST. 5 - 6 Precautions for ST (Self-tuning)

For example, when the sum of LSP group selection values of internal contact 1 to 3 is "1", the LSP group number becomes "2". • Even though the LSP system group is "1", the display and setting can be made, but the LSP group selection with the internal contact function becomes invalid.

� � SP ramp unit The unit of the SP up/down ramp can be set. Item (Bank) Display Contents Initial value User level SP ramp unit (Setup bank) 0: 0.1 U/s 1: 0.1 U/min 2: 0.1 U/h 0 High function • "0.1U" shows that the decimal point position of the PV is shifted one digit rightward. Example: When the thermocouple input is in a range of -200 to +1200 °C, "0.1 U" is "0.1 °C". Example: When the DC voltage input is in a range of 0.0 to 100.0, "0.1U" is "0.01". For the relationship between the decimal point position and the type of PV input range, refer to the next section, "� SP ramp-up/ramp-down." Handling Precautions When using the DC voltage/DC current input with setting of 3 digits after the decimal point, "0.1U" is "0.0001". However, the SP up ramp/SP down ramp setting cannot display 4 digits after the decimal point, the value is displayed without use of the decimal point. � � SP up ramp/down ramp The SP up ramp and down ramp can be set. Item (Bank) Display Contents Initial value User level SP up ramp (Parameter bank) 0.0U: No ramp 0.1 to 999.9 U (The unit of the ramp time is selected using the SP ramp unit.) 0.0 U High function SP down ramp (Parameter bank) 0.0 U • When an initial value of “0.0U” is set, the SP ramp function does not function. Therefore, when the up ramp setting is set to “0.1U” or more and the down ramp is set to “0.0 U”, the SP ramp functions only during SP up and the SP ramp does not function during SP down. Additionally, the reverse operation can also be set so that the SP ramp functions only during SP up and it does not function during SP down. • Regarding the setting for the number of digits after the decimal point (C04), the SP ramp display shows one digit more than is shown for the PV. For linear input, if C04 is set for 3 digits after the decimal point, no decimal point is displayed in the SP ramp value, but all 4 displayed digits are after the decimal point.
