Input power phase
sequence state
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

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.
