Torque Control - YASKAWA varispeed G7 CIMR-G7B series Instruction Manual

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.

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

-: Opposite of Run Command
Speed limit bias Set the speed limit bias as a per-
centage of the maximum output
frequency.
d5-05 Bias is applied to the specified

speed limit. It can be used to
adjust the margin for the speed
limit.
