High-Speed Operation at Light Load
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 established in
F341.
This parameter may be disabled.
If either of the other selections are made and configured,
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.

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
the frequency setting here.
Light-Load High-Speed Operation Load Wait Time
Program Special Crane/Hoist Load
After the time setting of F333
time that the Light-Load High-Speed criteria must be met until the Light-
Load High-Speed function engages.
Light-Load High-Speed Operation Load Detection Time
Program Special Crane/Hoist Load
This parameter determines the length of time that the load requirement must
meet the Light-Load High-Speed criteria before the Light-Load High-Speed
Enable (F330) is recognized.
Once recognized, the timer setting of
