8.3 Fault Information and Troubleshooting
If an alarm is reported, the system performs corresponding processing based on the fault level.
You can handle the fault according to the possible causes described in the following table.
Table 8-3 Fault codes and troubleshooting
Fault
Code
Name Possible Causes Solution Level
Err02
Overcurrent
during
acceleration
• The main circuit
output is grounded or
short circuited.
• Motor auto-tuning is
performed improperly.
• The load is too heavy.
• The encoder signal is
incorrect.
• The EPS running
feedback signal is
incorrect.
• Check whether the RUN contactor
at the controller output side is
normal.
• Check:
- Whether the power cable jacket
is damaged
- Whether the power cable is
possibly short circuited to ground
- Whether the power cable is
connected reliably
• Check the insulation of motor
power terminals, and check
whether the motor winding is
short-circuited or grounded.
• Check whether shorting PMSM
stator causes controller output
short circuit.
• Check whether motor parameters
comply with the nameplate.
• Perform motor auto-tuning again.
• Check whether the brake keeps
released before the fault occurs
and whether the brake is stuck
mechanically.
• Check whether the balance
coefficient is correct.
• Check whether the encoder
wirings are correct. For
asynchronous motor, perform
SVC and compare the current to
judge whether the encoder works
properly.

Err03
Overcurrent
during
deceleration
• The main circuit
output is grounded or
short circuited.
• Motor auto-tuning is
performed improperly.
• The load is too heavy.
• The deceleration rate
is too short.
• The encoder signal is
incorrect.
