5 Troubleshooting
5
Fault Code Name Possible Causes Solution Level
Err13
Power output
phase loss
The output wiring of
the main circuit is
loose.
• Check whether the motor wiring is secure.
• Check whether the RUN contactor on the
output side is normal.
5A
The motor is
damaged.
Eliminate the motor fault.
Err14
IGBT overheat
The ambient
temperature is too
high.
Reduce the ambient temperature.
5A
The fan is damaged.
Replace the damaged fan.
The air lter is
clogged.
• Clear the air lter.
• Check whether the installation clearance of
the controller satises the requirement.
Err15
Output abnormal
Subcode 1: The
braking resistor is
short-circuited.
• Check that wiring of the braking resistor and
braking unit is correct, without short circuit.
• Check whether the main contactor works
properly and whether there is arch or stuck
problem.
5A
Subcode 2: The
braking IGBT is short-
circuited.
Contact us or our agent directly.
Err16
Current control
fault
Subcode 1: The
current deviation is
too large.
• Check whether the input voltage is low (often
in temporary power supply).
• Check whether cable connection between
the controller and the motor is secure.
• Check whether the RUN contactor works
properly.
5A
Subcode 2: The
speed deviation is too
large.
Subcode 3: The
speed deviation is too
large.
• Check the circuit of the encoder:
• Check whether encoder pulses per revolution
(PPR) is set correctly.
• Check whether the encoder signal is
interfered with.
• Check whether the encoder cable runs
through the duct independently, whether the
cable is too long, and whether the shield is
grounded at one end.
• Check whether the encoder is installed
reliably, whether the rotating shaft is
connected to the motor shaft reliably by
observing whether the encoder is stable
during normal-speed running.
• Check whether the motor parameters are
correct, and perform motor auto-tuning
again.
• Increase the torque upper limit in F2-08.
