Torque Reference Adjustment: d5-02, H3-02 to H3-11
Primary Delay Time Constant for Torque Reference Filter: d5-02
D
The time constant of the primary filter in the torque reference section can be adjusted.
D
This constant is used to eliminate noise in the torque reference signal and adjust the responsiveness
to the host controller.

D
Set the torque reference filter primary delay time constant in ms units.
D
Increase the time constant setting if oscillation occurs during torque control operation.
Setting the Torque Compensation: H3-05, -04, -08, -09
D
Set multi-function analog input (terminal 16) or frequency reference current input (terminal 14) to
torque compensation (setting 14). When the amount of torque loss at the load is input to one of these
terminals, it is added to the torque reference to compensate for the loss.
