Possible cause
Communication line fault.
Incorrect communication
address.
Communication suffers from
strong interference.
Incorrect baud rate.
Communication line fault.
Incorrect communication
address.
Inverter output is short
connected to the ground;
Current detection circuit is
faulty;
Actual motor power setup
deviates sharply from the
inverter power.
Inverter output is short
connected to the ground;
Current detection circuit is
faulty;
Actual motor power setup
deviates sharply from the
inverter power.
Load is too heavy, or stall
occurred.
Control parameters of the
synchronous motor is set
improperly;
The parameter gained from
autotuning is inaccurate;
The inverter is not
connected to the motor.
The inverter performs the
underload pre-alarm based
on the set value
Encoder line sequence is
wrong, or signal wires are

Troubleshooting
Solution
to enhance the
anti-interference capacity.
Check the communication
interface cable.
Set the communication
address correctly.
Replace or change the wiring
to enhance the
anti-interference capacity.
Set a proper baud rate.
Check the communication
interface cable.
Set the communication
address correctly.
Replace or change the wiring
to enhance the
anti-interference capacity.
Check whether the
wiring is proper;
Replace the hall component;
Replace the main control
board;
Reset the motor parameters
properly.

wiring is proper;
Replace the hall component;
Replace the main control
board;
Reset the motor parameters
properly.
Check the load to ensure it is
proper, and increase
detection time;
Check whether the control
parameters are set properly.
