No light load speed boost due to current
verification failure
If light load speed boost mode 1 is enabled,
processing for light load speed boost is
performed only when the set frequency is no
less than P02.02 (Motor rated frequency). After
running, if the ramp frequency is equal to or
greater than P91.10, current is detected and
count starts. When P91.11 is reached, if the
current is less than P91.12 (or P91.13 in
reverse running), the current detection passes,
the VFD increases the frequency to P91.09. If
the current detection fails, the VFD remains the
original frequency.
Note:
The
light-load
frequency setting must be higher than the set
frequency. Otherwise, speed boost cannot be
implemented although the conditions are met. If
the set frequency is higher than P91.10, the
original frequency is remained.
Setting range of P91.09: 0.00–100.00Hz
P91.10 setting range: 50.0%–100.0% (of the
motor rated frequency)
