Code Fault Message Possible reasons Remedy
F032 Fan Motor2 Fault 1. Motor is in locked-rotor
state.
2.The wire connection be-
tween fan controller and fan
motor is in poor contact. 1.Change a new fan motor
2.Check the wire connection
and make sure they are in
good contact.
F01 Drv1 MOP alarm MOP drive alarm Recovery after the 150s
F02 Inverter offline Frequency conversion board
and main board communica-
tion failure. Check the communication
connection.
F03 IPM protection IPM modular protection Recovery after the 150s
F04 Comp. Driver Failure Lack of phase, step or drive
hardware damage. Check the measuring voltage
and frequency conversion
board hardware.
F05 DC Fan Fault Motor current feedback open
circuit or short circuit. Check whether current re-
turn wires connected motor.
F06 IPM Overcurrent IPM Input current is large. Check and adjust the current
measurement.
F07 Inv. DC Overvoltage DC bus voltage>Dc bus
over-voltage protection
value. Check the input voltage
measurement.
F08 Inv. DC Lessvoltage DC bus voltage<Dc bus
over-voltage protection
value. Check the input voltage
measurement.
F09 Inv. Input Lessvolt. The input voltage is low,
causing the input current is
high. Check the input voltage
measurement.
F10 Inv. Input Overvolt. The input voltage is too high,
more than outage protection
current RMS. Check the input voltage
measurement.
F11 Inv. Sampling Volt. The input voltage sampling
fault. Check and adjust the current
measurement
F12 Comm. Err DSP-PFC DSP and PFC connect fault. Check the communication
connection.
F26 Input Over Cur. The equipment load is too
large.
F27 PFC fault The PFC circuit protection. Check the PFC switch tube
short circuit or not.
F15 IPM Overheating The IPM module is overheat Check and adjust the current
measurement.
F16 Weak Magnetic Warn Compressor magnetic force
is not enough.
