Reason
DC bus voltage<Dc bus over-voltage
protection value
The input voltage lost phase
Lack of phase, step or drive hardware
damage
DSP and PFC connect fault
Transducer temperature is too
high
Frequency conversion board and main
board communication failure
The input voltage is too high, more than
outage protection current RMS
Sensor is short circuit or open
circuit
IPM Input current is large
DSP and MCU connect fault
Input current is too large
MOP drive alarm
The input voltage is low, causing the
input current is high
IPM sampling electricity is fault
Motor current feedback open circuit or
short circuit
DSO and SPPB connect fault
Compressor electricity is large
IPM modular protection
The input voltage sampling fault
The transducer is overheat
DC bus voltage>Dc bus over-voltage
protection value
Compressor magnetic force is not
enough
The IPM module is overheat
MCU error
