Code Modbus ID Parameter Application RO/RW
P7.4.1.1 1330 PID1 Feedback Function 2,3 RW
Use this paramter to select if the feedback value is taken form a single signal or a combination of
two signals. The mathematical functions can be selected that is used when two feedback signals
are combined.
P7.4.1.2 1331 PID1 Feedback Gain 2,3 RW
Use this parameter to set the gain associated with feedback signal from the measuring signals defined
in the feedback function.
P7.4.2.1 1332 PID1 Feedback 1 Source 2,3 RW
Use this paramter 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 paramter 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 paramter 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%.
