Quit
frequency of
over
frequency
derating
Specifies the frequency
threshold for exiting
overfrequency derating.
Hz
When the output
frequency is 50 Hz,
the value range is
[45.00, 55.00].
When the output
frequency is 60 Hz,
the value range is
[55.00, 65.00].
The parameter
setting should
meet the
following
condition:
Quit

.
10
Cutoff
frequency of
overfrequenc
y derating
Specifies the frequency
threshold for cutting off
overfrequency derating.
Hz
When the output
