Switching Between Torque and Speed Control
n
Use a digital output to switch Torque Control and Speed Control (H1-
Torque Control, the torque limit becomes the torque reference and the speed reference becomes the speed limit. This
change is reversed when switching back to Speed Control.
If required by the application, set up a delay time using parameter d5-06. The reference values (torque reference/speed
limit in Torque Control or speed reference/torque limit in Speed Control) are held during this switch delay time. Change
the reference values from the controller within this delay time.
Note: 1. The switching delay time d5-06 is not applied when the Stop command is entered. Here the operation switches immediately to speed
control and the drive decelerates to a stop at the torque limit.
2. Set d5-01 to 0 when switching between Torque Control and Speed Control. An oPE15 alarm will be triggered if parameter d5-01 is
set to 1 while H1-

Apply a filter with the time constant set in parameter d5-02 to the torque reference signal in order to eliminate oscillation
that results from an unstable torque reference signal. A higher filter time will stabilize control, but also reduce the
responsiveness.
