Code Modbus ID Parameter Application RO/RW
P7.4.2.1 1332 PID1 Feedback 1 Source 2,3 RW
Use this parameter is used to select where feedback signal is being fed into the drive. This signal could be
defined as analog inputs or fieldbus data value.
P7.4.2.2 1333 PID1 Feedback 1 Min 2,3 RW
Use this parameter to set the minimum unit value for the feedback signal.
P7.4.2.3 1334 PID1 Feedback 1 Max 2,3 RW
Use this parameter to set the maximum unit value for the feedback signal.
P7.4.3.1 1335 PID1 Feedback 2 Source 2,3 RW
Use this parameter is used to select where feedback signal is being fed into the drive. This signal could be
defined as analog inputs or fieldbus data value.
P7.4.3.2 1336 PID1 Feedback 2 Min 2,3 RW
Use this parameter to set the minimum unit value for the feedback signal.
P7.4.3.3 1337 PID1 Feedback 2 Max 2,3 RW
Use this parameter to set the maximum unit value for the feedback signal.
P7.5.1.1 1338 PID1 Feedforward Func 2,3 RW
Use this parameter to select if the feedforward value is taken form a single signal or a combination of two
signals. The mathamatical functions can be selected that is used when two feedback signals are combined.
P7.5.1.2 1339 PID1 Feedforward Gain 2,3 RW
Use this parameter to set the gain associated with feedforward signal from the measuring signals defined in
the feedback function.
P7.5.2.1 1340 PID1 Feedforward 1 Source 2,3 RW
Use this parameter is used to select where feedforward signal is being fed into the drive. This signal could be
defined as analog inputs or fieldbus data value.
P7.5.2.2 1341 PID1 Feedforward 1 Min 2,3 RW
Use this parameter to set the minimum unit value for the feedforward signal.
P7.5.2.3 1342 PID1 Feedforward 1 Max 2,3 RW
Use this parameter to set the maximum unit value for the feedforward signal.
P7.5.3.1 1343 PID1 Feedforward 2 Source 2,3 RW
Use this parameter is used to select where feedforward signal is being fed into the drive. This signal could be
defined as analog inputs or fieldbus data value.
P7.5.3.2 1344 PID1 Feedforward 2 Min 2,3 RW
Use this parameter to set the minimum unit value for the feedforward signal.
P7.5.3.3 1345 PID1 Feedforward 2 Max 2,3 RW
Use this parameter to set the maximum unit value for the feedforward signal.
P8.1.1 1356 PID2 Control Gain 2,3 RW
This parameter is used to defines the proportional gain of the PID Controller. It adjust the slope of the speed
increase according to the initial of the load. If this value is set to 100% a change of 10% in the error value
causes the controller output to change 10%.
P8.1.2 1357 PID2 Control I Time 2,3 RW
This parameter is used to defines the integration time constant of the PID Controller. Over the time the
integral time contributes to the deviation between the reference and the feedback signal. If this value is set
to 1.00 sec, a change of 10% in the error value causes the controller output to change by 10.00%/s. With
value set to 0.0, frequency converter operates as PD controller.
P8.1.3 1358 PID2 Control D Time 2,3 RW
This parameter is used to defines the derivation time constant of the PID Controller. This value will adjust the
rate of change on the feedback signal. If this value is set to 1.00 sec, a change of %10 in error value during
1.00 sec causes the control output to change by %10.00. If value is set to 0.0, frequency converter operates
as PI controller
P8.1.4 1359 PID2 Process Unit 2,3 RW
This parameter is used to defines the unit type for PID controller. This will change the Feedback and Setpoint
variables to show the desired unit of measure.
P8.1.5 1360 PID2 Process Unit Min 2,3 RW
This parameter is used to defines the minimum process unit value for the PID controller.
