count starts. When P91.11
current is less than P91.12
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 speed-boost target
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.
P91.09 setting range: 0.00–100.00Hz
P91.10 setting range: 50.0%–100.0% (of the
motor rated frequency)
P91.11 setting range: 0.0–10.000s
P91.12, P91.13setting range: 0.0–150.0%
Note: Light load speed boost mode 1 is
applicable to the open-loop mode.

When the set frequency is greater than the
heavy load speed-limit detection frequency
(P91.14), the motor running frequency becomes
stable after reaching the detection frequency
(P91.14), and load detection is performed after
the time specified by P91.15. The load detection
value is used for heavy load speed limit
calculation. The load detection value
be viewed through the keypad.
