VS-616G5 Programming Manual 51

· When [-1 × speed limit bias (D5-05)] < motor speed < [speed limit + D5-05], torque control is acti-

vated using the set torque reference.

· When motor speed > [speed limit + D5-05], torque control is activated using the set torque refer-

ence.

· When motor speed < [-l × D5-05], the speed limiting circuit outputs a positive torque reference to

prevent the motor speed from increasing in the reverse direction.

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 reference, speed limit

and motor speed.
