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.
