Drooping Control
This parameter sets the method to be used in determining the output torque
while operating in the
Drooping Control mode.
Settings:
0 — Total Torque Calculated by the Detection Current.
1 — Torque without Acc/Dec Torque Calculated by Detection Current.
2 — Total Torque Calculated by the Command Current.
3 — 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 — Yes

Crane/Hoist Load
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.
Settings:
0 — Disabled
1 — Reserved
2 — Automatic Enable - Automatic Speed (
F341 )
3 — Automatic Enable - Preset Speed (Preset ID

Crane/Hoist Load
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.
Direct Access Number — F331
