Code Parameters Meaning Fault Solution
1
Compressor
Over-current
1. The compressor is temporarily overloaded (for example, liquid
compression)
2. The program does not match the compressor
3. The U, V, and W lines of the compressor are inversely connected, and the
compressor reverses
4. Compressor wear (lack of oil, liquid compression lead to wear cylinder
block)
2
Compressor out of
step
1. The compressor is temporarily overloaded (for example, liquid
compression)
2. The program does not match the compressor
3. The compressor start pressure difference is too high and low.
8
Compressor phase
loss
1. Cables U, V, and W of the compressor are missed or improperly connected
2. The program does not match the compressor
3. The compressor starts too high and low pressure difference
16 DC voltage is too low
1. Check whether the AC voltage is abnormal
2. AC power is suddenly cut off, and the DC voltage will be too low when the
converter capacitor is left for the chip to work
32
DC voltage is too
high
Check whether the AC voltage is abnormal
257
Communication is
abnormal
1. Check whether the communication cable is improperly connected
2. Check whether the baud rate and communication address code are set
according to the communication protocol
3. Replace the driving board for testing
258
AC phase loss or CT
is disconnected
1. The current transformer on the driving board is damaged during
transportation
2. Check whether the current transformer is improperly inserted during
production
3. The AC current at the frequency above 40Hz is very small, resulting in
abnormal detection of the current transformer
260
AC over-current or
compressor
overpower
1. AC overcurrent (currently available for external models with a separate filter
board), the load is suddenly too large to reduce the frequency
2. Compressor overpower (combined plate, three-phase 380V, no single filter
plate model) the load is suddenly too large to reduce the frequency too late
3. Compressor overpower (combined plate, three-phase 380V, models
without separate filter plate) The compressor starts too high and low pressure
difference
288
IPM over heat
protection
1. The heat dissipation is poor. The condensing fan rotates at a low speed or
stops unexpectedly
2. The ambient temperature rises too fast, leading to too late reaction of
over-temperature frequency reduction
