If the VFD enables phase sequence detection
and input phase loss hardware protection,
corresponding fault will be reported when
negative sequence and any phase loss
occurs; otherwise, fault will not be reported.
0: Positive sequence
1: Negative sequence
2: R phase loss
3: S phase loss
4: T phase loss
0: Normal, indicating the flat cable is plugged
in properly
1: Abnormal, indicating the flat cable is not
cable

0.0–40.0A
This function code is related to current
detection and overload protection function of
power-frequency fan.
Set to 0 will disable this function.
1.0–4000.0
1.00–3.00
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.
0.0–150.0%
Actual current=display current*current
calibration coefficient
Note: When restoring to default values, this
value will stay in currently set value.
