MOP drive alarm
Frequency conversion board and main
board communication failure
IPM modular protection
Lack of phase, step or drive hardware
damag
Motor current feedback open circuit or
short circuit
IPM Input current is large
DC bus voltage>Dc bus over-voltage
protection value
DC bus voltage<Dc bus over-voltage
protection value
The input voltage is low, causing the
input current is high
The input voltage is too high, more than
outage protection current RMS
The input voltage sampling fault
DSP and PFC connect fault
The equipment load is too large

Communication Fault
(speed control module)
Fan Motor2 Fault
Speed control module and main
board communication fail
Check the communication connection
1. Motor is in locked-rotor state
2.The wire connection between
DC-fan motor module and fan
motor is in bad contact
1.Change a new fan motor
2.Check the wire connection and make sure
they are in good contact
