Function:
Select to operate in open loop.
Select to use torque feedback from
the analog input.
Select to use torque feedback from
the analog input.
Select to use the torque feedback
estimated by the frequency
converter.
Function:
[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.
Function:
[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.
Function:
[0.1 - 100 Enter the time constant for the
torque control low-pass filter.
Function:
[0 - 100 %] Enter the torque feed forward
factor value. The reference signal
bypasses the torque controller by
this value.
Function:
[15 - 100 %] Enter the value for the rise time of
the current controller as a
percentage of the control period.
