Section D: Reference Parameters
D5 Torque Control
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.
