Parameter Descriptions
3.8.4 7-1* Torque PI Control
Parameters for configuring the torque PI control.
7-10 Torque PI Feedback Source
Select the feedback source for the torque controller.
Option: Function:
[0] Controller Off Select to operate in open loop.
*
[1] Analog Input 53 Select to use torque feedback from the
analog input.
[2] Analog Input 54 Select to use torque feedback from the
analog input.
[3] Estimed Torque Select to use the torque feedback
estimated by the frequency converter.
7-12 Torque PI Proportional Gain
Range: Function:
100 % [0 - 500 %] 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.
7-13 Torque PI Integration Time
Range: Function:
0.020 s [0.002 - Enter the integration time for the
*
2.000 s] torque controller. Selection of a low
value makes the controller react faster.
Too low a setting leads to controller
instability.
7-16 Torque PI Lowpass Filter Time
Enter the time constant for the torque control low-pass filter.
Range:
5 ms [0.1 - 100 ms]
*
7-18 Torque PI Feed Forward Factor
Enter the torque feed forward factor value. The reference signal
bypasses the torque controller by this value.
Range:
0 % [0 - 100 %]
*
7-19 Current Controller Rise Time
Range: Function:
Size related [15 - 100 %] Enter the value for the rise time of
*
the current controller as a
percentage of the control period.

Function:
The effective feedback signal is made
up of the sum of up to 2 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
parameter 7-22 Process CL Feedback 2
Resource.
