Parameter Descriptions
NOTE
Severe filtering can be detrimental to dynamic
performance.
This parameter is used with H-40 Configuration Mode [1]
Speed closed loop and [2] Torque control.
The filter time in flux sensorless must be adjusted to
3-5 ms.

[0.0001 - 32.0000]
Function:
[0 - 500 %] The reference signal bypasses the speed
controller by the amount specified. This
feature increases the dynamic performance
of the speed control loop.
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 control instability.
Function:
The effective feedback signal is made
up of the sum of up to two different
input signals.
