This parameter is used to eliminate noise in the torque reference signal and adjust the responsiveness
to the host controller. This parameter cannot be changed during operation.

Note 1. Set the torque reference filter’s primary delay time constant in ms units.
Note 2. Increase the time constant setting if vibration occurs during torque control operation.

Setting the Torque Compensation Bias
•
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.

Note 1. Set the proper signal level for the torque compensation bias that you want to input.
Note 2. The direction of the torque compensation bias is determined by the sign (polarity) of the signal
that is input. It is not determined by the direction of the run command (forward/reverse).
+Voltage (or current): Forward torque compensation
(generally counter-clockwise; axis side)
–Voltage:
Reverse torque compensation (generally clockwise; axis side)
Since the polarity of the voltage input determines the direction, only forward torque compen-
sation can be input when the “0 to +10 V” or “4 to 20 mA” signal level has been selected. If you
want to input reverse torque compensation, be sure to select the “0 to
±
10 V” signal level.
