Reference
This parameter sets the method to be used in determining the output torque
while operating in the Drooping Control mode.
Settings:
Total Torque Calculated by the Detection Current.
Torque without Acc/Dec Torque Calculated by Detection Current.
Total Torque Calculated by the Command Current.
Torque without Acc/Dec Torque Calculated by the Command Current.
Direct Access Number — F327
Parameter Type — Selection List
Factory Default — Total torque
calculated by the detection current
Changeable During Run — Ye s
Light-load High-speed Operation Selection
Program ⇒ Special Control Parameters ⇒ Crane/Hoist Settings ⇒
Express Speed Settings ⇒ Light-Load High-Speed Operation
This parameter enables the Light-Load High-Speed function by selecting an
operating mode. The Light-Load High-Speed function accelerates the output
frequency of the ASD from the programmed speed to the setting established in
F341.
This parameter may be disabled.
If either of the other selections are made and configured, and after the
criteria of
F331 – F333 are met, the Light-Load High-Speed function is
enabled and this parameter determines the operating mode of the Light-Load
High-Speed function.

Switching Lower-Limit Frequency
This parameter sets an output frequency threshold that, once surpassed, allows
the Light-load High-speed function to be used.
The Light-Load High-Speed function may be used if the frequency threshold
(
F331) and the following conditions are met:
1) Light-Load High-Speed Operation Enable is configured at F330.
2) The output torque is less than the setting established in F335 when reaching
the frequency setting here.
