‹ Torque Control
With flux vector control or open-loop vector control 2, the motor's output torque can be controlled by a torque
reference from an analog input. Set d5-01 to 1 to control torque.

Torque Control
Selection Selects speed or torque control.
The torque reference is set via
analog input A2 or A3 when it is
set for "torque reference" (H3-05
or H3-09 = 13). Torque reference
is set as a percentage of motor
rated torque. To use this function
for switching between speed and
torque control, set to 0 and set a
multi-function input to "speed/
torque control change" (H1-xx =
71).

Delay Time Sets the torque reference delay

This function can be used to
correct for noise in the torque
control signal or the
responsiveness with the host
controller. When oscillation
occurs during torque control,
increase the set value.
