Torque Control
With Flux Vector Control, the motor’s output torque can be controlled by a torque reference from an analog
input. To carry out the torque control, set d5-01 to 1 or H1- (Multi-function digital input) to 71 for speed
or torque control, and then turn on the contact.

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.”

Delay Time
Set the torque reference delay time in ms
units.
This function can be used to adjust the noise
of the torque control signal or the responsive-
ness 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 d5-03 is set to

PID Output Limit
Set the delay time from inputting the multi-
function input “speed/torque control change”
(from on to off or off to on) until the control is
actually changed, in ms units.
This function is enabled when the multi-func-
tion input “speed/torque control change” is
set. In the speed/torque control switching
timer, the analog inputs hold the values of
when the “speed/torque control change”
changes. Always be sure to allow time for this
process to finish completely.
