Therefore, when torque reference > 0 and speed limit (%) > 0, the torque control
range is:
[-l × D5-05] < motor speed < [speed limit + D5-05]
Refer to the following table for more details on the relationship between torque refer-
ence, speed limit, and motor speed.
Speed/Torque Control Switching
•
Speed control or torque control can be selected “on the fly” by using the multi-
function input speed/torque control selection command (H1-XX = “71”).
