Function:
[0 - 500 %] Enter the proportional gain value for the
torque controller. Selection of a high value
makes the contoller react faster. Too high
a setting leads to controller instability.
Function:
[0.002 - 2 s] Enter the integration time for the torque
controller. Selection os a low value make
the controller react faster. Too low a
setting leads to controller instability.
Function:
The effective feedback signal is made up
of the sum of up to 2 different input
signals. Select which input should be
treated as the source of the first of these
signals. The second input signal is
defined in parameter 7-22 Process CL
Feedback 2 Resource.
