824 Torque control P gain 1
Set the proportional gain for the current control of the q and d axes. (Increasing the
value improves trackability in response to a current command change and reduces
current variation with disturbance.)

825
Torque control
integral time 1
Set the integral time for the current control of the q and d axes. (Decreasing the value
shortens the time taken to return to the original torque if current variation with
disturbance occurs.)

826 Torque setting filter 1
Set the primary delay filter for the analog voltage (terminal 3)-based torque command
value. (Also valid for the torque limit from the terminal 3 during speed control.)

Torque biases
840 Torque bias selection
The torque bias function is designed to quicken the rise of torque at a motor start. You
can set the then output torque using the parameters or analog signals.

841 Torque bias 1
Set the torque bias values when you chose internal parameter-based torque bias
selection. Assign X42 (torque bias selection 1) and X43 (torque bias selection 2) to the
input terminals.
