Torque Control
Please consult factory for application assistance regarding torque control. Typically, torque control
should not be applied on a hoist.
This function is used to avoid excessive changes in torque, which may be caused by abnormal
resonance when the torque reference changes rapidly.
Table 5-48: Torque Control Parameter Settings
NOTE: Speed/torque control selection can also be made by using a multi-function input select
(H01-xx = 34 speed-torque control changeover).
