7-08 Speed PID Feed Forward Factor
Range: Function:
0 %
*
[0 - 500 %] The reference signal bypasses the speed
controller by the amount specified. This
feature increases the dynamic performance
of the speed control loop.
7-09 Speed PID Error Correction w/ Ramp
Range: Function:
300 RPM
*
[10 - 100000
RPM] The speed error between ramp and
actual speed is held up against the
setting in this parameter. If the speed
error exceeds this parameter entry,
the speed error will be corrected via
ramping in a controlled way.

3.9.2 7-1* Torque PI Control
Parameters for configuring the torque PI control in torque
open loop (
1-00 Configuration Mode ).
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 - 2.000
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 control
instability.
3.9.3 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 two 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
