Drooping Reference
Program Feedback 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.
Light-Load High-Speed Operation
Program Special 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
.

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

Light-Load High-Speed Operation Switching Lower-Limit Frequency
Program Special 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
reaching the frequency setting here.
