7-13 Torque PI Integration Time
Range: Function:
0.020 s* [0.002 - 2.000 s] Enter the integration time for the torque controller. Selection of a low value makes the controller
react faster. Too low a setting leads to control instability.
3.9.4 7-2* Process Ctrl. Feedb.
Select the feedback sources for the Process PID Control, and how this feedback should be handled.
7-20 Process CL Feedback 1 Resource
Option: Function:
The effective feedback signal is made up of the sum of up to two different input signals.
Select which frequency converter input should be treated as the source of the first of these signals.
The second input signal is defined in par. 7-22

7-22 Process CL Feedback 2 Resource
Option: Function:
The effective feedback signal is made up of the sum of up to two different input signals. Select
which frequency converter input should be treated as the source of the second of these signals. The
first input signal is defined in par. 7-21.

3.9.5 7-3* Process PID Ctrl.
Parameters for configuring the Process PID control.
7-30 Process PID Normal/ Inverse Control
Option: Function:
Normal and inverse control are implemented by introducing a difference between the reference
signal and the feedback signal.
[0] * Normal Sets process control to increase the output frequency.
[1] Inverse Sets process control to reduce the output frequency.
