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 - 2 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 controller instability.
7-16 Torque PI Lowpass Filter Time
Enter the time constant for the torque control low-pass filter.
Range:
Function:
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:
Function:
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.
3.8.5 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 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
