Solution
lost in operation
value
P7-27 to an appropriate value
Err51
Switch motor in
operation
In the process of inverter operation, change
the current motor selection through the
terminal
Switch the motor after the frequency
converter stops
Err52
Speed offset too
large
1. Encoder parameter setting incorrect
2. Motor blocked
3. Incorrect UVW wiring
1. Setting encoder parameters correctly
2. Check whether the machine is
abnormal
3. Check whether the wiring between
frequency converter and motor is
abnormal
Err53
Motor overspeed
fault
1. Incorrect setting of encoding parameters
2. The motor is not tuned
3. Unreasonable setting of motor over speed
detection parameters P7-63 and P7-64
1. Setting encoder parameters correctly
2. Tuning correctly
3. Set reasonable parameters according
to the actual situation
Err54
Motor overheat
fault
1. Loose wiring of temperature sensor
2. Motor temperature too high
1. Check the wiring of temperature
sensor
2. Reduce the carrier wave or take
other measures to dissipate the motor
heat.
Err55
Motor
overtemperature
fault
1. The temperature sensor wiring is loose
2. Motor temperature is too high
1. Check the temperature sensor wiring
and eliminate the fault
2. Reduce the carrier frequency or take
other measures to cool the motor
Err56

Power on time arrival
When the usage time arrives, please
enter the password in A4-00.
7-2. Fault record query
This series of inverter records the fault codes and operation parameters of the inverter for the last three times.
Querying these information is helpful to find out the cause of the fault. All fault information is saved in P7
group parameters. Please refer to the keyboard operation method to enter P7 group parameters to check the
information.
7-3. Fault reset
In case of a failure of the inverter, to resume normal operation, you can select any of the following operations:
(1) When the fault code is displayed, press stop after confirming that it can be reset.
(2) Set any terminal of X1-X4 to reset stop input for external fault, and then disconnect from com terminal after
closing.
(3) Cut off the power supply.
Note:
(1) Before reset, the reason of the fault must be thoroughly identified and eliminated, otherwise, the permanent
damage of the frequency converter may be caused.
(2) If the fault cannot be reset, check the reason, and the continuous reset will damage the inverter.
(3) When overload and overheating protection acts, it shall be reset 5 minutes later.
