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 UPS 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
coefcient 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.

circuited.
•
Motor auto-tuning is
performed improperly.
•
The load is too heavy.
•
The deceleration rate is
too short.
•
The encoder signal is
