Fault
Code
Name Possible Causes Solution Level
Err04
Overcurrent at
constant speed
•
The main circuit
output is grounded or
short circuited.
•
Motor auto-tuning is
performed properly.
•
The load is too heavy.
•
The encoder is
seriously interfered
with.
•
Check
- Whether the encoder is installed
reliably
- Whether the rotating shaft is
connected to the motor shaft
reliably
- Whether the encoder is stable
during normal-speed running
•
Check whether EPS feedback is
valid in the non-EPS running state
(E02).
•
Check whether the acceleration/
deceleration rate is too high (E02,
E03).
5A
Err05
Overvoltage
during
acceleration
•
The input voltage is
too high.
•
The regeneration
power of the motor is
too high.
•
The braking
resistance is too
large, or the braking
unit fails.
•
The acceleration rate
is too short.
•
Adjust the input voltage. Observe
whether the bus voltage is normal
and whether it rises too quickly
during running.
•
Check for the balance coefcient.
•
Select a proper regen. resistor
and check whether the resistance
is too large based on the
recommended braking resistance
table in chapter 3.
•
Check:
- Whether the cable connecting the
regen. resistor is damaged
- Whether the cooper wire touches
the ground
- Whether the connection is reliable

Err06
Overvoltage
during
deceleration
•
The input voltage is
too high.
•
The braking
resistance is too
large, or the braking
unit fails.
•
The deceleration rate
is too short.
5A
Err07
Overvoltage at
constant speed
•
The input voltage is
too high.
•
The braking
resistance is too
large, or the braking
unit fails.
