Parameter 7-10 Torque PI Feedback Source
Table 377: Parameter 7-10 Torque PID Feedback Source
7-10 Torque PID Feedback Source
Default value: [0] Controller off
Conversion index: –
Select the feedback source for the torque controller.
Option Name
[0]* Controller off
[1] Analog input 53
[2] Analog input 54
[3] Estimated torque
Parameter 7-12 Torque PI Proportional Gain
Table 378: Parameter 7-12 Torque PI Proportional Gain
7-12 Torque PI Proportional Gain
Default value: 100%
Conversion index: 0
Enter the proportional gain value for the torque controller. Selection of a high value makes the controller react faster. Too high a
setting leads to controller instability.
Parameter 7-13 Torque PI Integration Time
Table 379: Parameter 7-13 Torque PI Integration Time
7-13 Torque PI Integration Time
Default value: 0.020 s
Conversion index: -3
Enter the integration time for the torque controller. Selection of a low value makes the controller react faster. Too low a setting
leads to controller instability.
Parameter 7-16 Torque PI Lowpass Filter Time
Table 380: Parameter 7-16 Torque PI Lowpass Filter Time
7-16 Torque PI Lowpass Filter Time
Default value: 5 ms
Conversion index: -4
Enter the time constant for the torque control low-pass filter.
Parameter 7-18 Torque PI Feed Forward Factor
Table 381: Parameter 7-18 Torque PI Feed Forward Factor
7-18 Torque PI Feed Forward Factor
Default value: 0%
Conversion index: 0
