P21.00
Rated current of the
fan
0.0–40.0A
This function code is related to current
detection and overload protection function of
power-frequency fan. If P21.00 is set to a
non-zero value, this function is enabled. If
P21.00 is set to 0, this function is disabled.

P21.03
Current imbalance
coefficient
1.00–5.00
Among the current of three phases of the
fan, if the ratio between max. current and
min. current is larger than P21.03, the VFD
displays fan current imbalance fault.

Actual current = Displayed current * current
calibration coefficient
Note: When restoring to default values, this
value will stay in currently set value.
