The switching frequency (D04-07) can also be controlled with a digital input programmed to “ASR gain switch”
(H01-xx = 37). When the digital input is OFF, the VFD uses the ASR gain level set by the pattern in
.
When the digital input is ON, D04-03 is used. The integral time set to D04-02 is used to change linearly between
these settings, as shown in
. The ASR gain enabled by a digital input overrides the switching frequency
set to D04-07.

5.3.5 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 5-49: Torque Control Parameter Settings
* Cannot set D05-01 = 1 for NLB Hoist; use Load Share MFDI (H01-xx = 66) instead.
