Torque Control
With flux vector control or open-loop vector 2 control, the motor's output torque can be controlled by a torque
reference from an analog input. To control torque, set d5-01 to 1 or set multi-function contact inputs H1-
to 71 (Speed/Torque control) and turn ON the contact.

1: Torque control
This function is only available in
flux vector control method. To
use the function for switching
between speed and torque control,
set to 0 and set the multi-function
input to “speed/torque control
change.”

This function can be used to
adjust the noise of the torque con-
trol signal or the responsiveness
with the host controller. When
oscillation occurs during torque
control, increase the set value.

Speed limit Set the speed limit during torque
control as a percentage of the
maximum output frequency.
This function is enabled when d5-

Bias is applied to the specified
speed limit. It can be used to
adjust the margin for the speed
limit.
