06. Troubleshooting
6.2 Frequency Conversion Board Fault Table
6.3 Parameter List
Protect/fault Fault Code Reason Elimination methods
IPM Overcurrent Shutdown Fault F00 IPM input current is large Check and adjust the current measurement
Compressor Activation Failure F01 Lack of phase/step or drive hardware damage
Check the measuring voltage
Check frequency conversion board hardware
PFC Fault F03 PFC circuit protection Check the PFC switch tube if short circuit or not
DC Bus Overload F05 DC bus voltage > Dc bus over-voltage protection value Check the input voltage measurement
DC Bus Underload F06 DC bus voltage < Dc bus over-voltage protection value Check the input voltage measurement
AC Input Underload F07 The input voltage is low, causing the input current to be low Check the input voltage measurement
AC Input Overload F08
The input voltage is too high, more than outage
protection current RMS
Check the input voltage measurement
Input voltage Sample Fault F09 The input voltage sampling fault Check and adjust the current measurement
Communication Failure
between DSP and PFC
F10 DSP and PFC connect fault Check the communication connection
Communication Fault (DSP) F11 DSP and main board communication ailure Check the communication connection
Communication Fault
(Inverter Board)
F12
Frequency conversion board and main
board communication failure
Check the communication connection
IPM Overheat Stop F13 The IPM module is overheat Check and adjust the current measurement
Weak Magnetism Alarm F14 Compressor magnetic force is not enough
Input voltage Lacking Phase F15 The input voltage underwent phase-loss Check and measure the voltage adjustment
IPM Current Sample Fault F16 IPM sampling electricity is faulty Check and adjust the current measurement
Sensor Fault of Module/Radiator F17 The temp. sensor is broken or short circuit
IGBT Power Device Overheat Alarm F20 The IGBT is overheating Check and adjust the current measurement
Overload Alarm F21 Compressor electricity is large Compressor over-current protection
AC Input Overcurrent Alarm F22 Compressor electricity is large Compressor over-current protection
EEPROM Fault Alarm F23 MCU error
Check whether the chip is damaged
Replace the chip
Destroyed EEPROM
Activation Ban Alarm
F24 MCU error
Check whether the chip is damaged
Replace the chip
LP 15V Underload Fault F25 The V15V is either overloaded or has low voltage
Check the V15V input voltage if in range
13.5V~16.5V or not
IGBT Power Device Overheat Fault F26 The IGBT is overheating Check and adjust the current measurement
