Fault
Code
Description Cause Troubleshooting Remarks
Er02
Overcurrent
during
acceleration
1. The main circuit output
is grounded or short-
circuited.
2. Motor auto-tuning is
performed improperly.
3. The load is too heavy.
1. Eliminate external faults
such as wiring error.
2. Perform motor auto-
tuning again.
3. Reduce the burst load.
Er03
Overcurrent
during
deceleration
1. The main circuit output
is grounded or short-
circuited.
2. Motor auto-tuning is
performed improperly.
3. The load is too heavy.
4. The deceleration rate is
too short.
1. Eliminate external
problems such as wiring
error.
2. Perform motor auto-
tuning again.
3. Reduce the burst load.
4. Modify the related
parameters.
Er04
Overcurrent
at constant
speed
1. The main circuit output
is grounded or short-
circuited.
2. Motor auto-tuning is
performed improperly.
3. The load is too heavy.
4. Strong interference
exists on the encoder.
1. Eliminate external
problems such as wiring
error.
2. Perform motor auto-
tuning again.
3. Reduce the burst load.
4. Choose a proper
encoder and uses a
shielded cable for the
encoder.
Er05
Overvoltage
during
acceleration
1. The input voltage is too
high.
2. The braking resistance
is too large.
3. The acceleration rate is
too short.
1. Reduce the input
voltage.
2. Choose a proper brake
resistor.
3. Modify the related
parameters.
Er06
Overvoltage
during
deceleration
1. The input voltage is too
high.
2. The braking resistance
is too large.
3. The deceleration rate is
too short.
1. Reduce the input
voltage.
2. Choose a proper brake
resistor.
3. Modify the related
parameters.
Er07
Overvoltage
at constant
speed
1. The input voltage is too
high.
2. The braking resistance
is too large.
1. Reduce the input
voltage.
2. Choose a proper brake
resistor.
Er09
Undervoltage
protection
1. Instantaneous power
failure occurs on the input
power supply.
2. The input voltage is too
low.
3. The control board is
abnormal.
1. Eliminate external power
supply problems.
2. Contact the agent or the
vendor.
The controller
resets
automatically
after the voltage
becomes
normal.
