Maximum value:
200.00%
Default value:
100.00%
Description:
Defines the gain of the PI 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%.

Minimum value:
0.00 s
Maximum value:
600.00 s
Default value:
1.00 s
Description:
Defines the integration time of the PI 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
