Fault
Code
Name Possible Causes Solution Level
Err08
Pre-charge
relay not close
at power-on
•
The external power
supply is not stable.
•
A hardware fault
occurs.
•
Check that the external power
supply is stable and that the
power input cables are connected
securely.
•
Do not power on the device again
when power-off is incomplete.
•
Contact the agent or Monarch if
the cause is hardware fault.
5A
Err09 Undervoltage
•
Instantaneous power
failure occurs on the
input power supply.
•
The input voltage is
too low.
•
The drive control
board fails.
•
Eliminate external power supply
faults and check whether the
power fails during running.
•
Check whether the wiring of all
power input cables is secure.
•
Contact the agent or Monarch.
5A
Err10
Controller
overload
•
The brake circuit is
abnormal.
•
The load is too heavy.
•
The encoder feedback
signal is abnormal.
•
The motor parameters
are incorrect.
•
A fault occurs on the
motor power cables.
•
Check the brake circuit and power
input.
•
Reduce the load.
•
Check whether the encoder
feedback signal and setting are
correct, and whether the initial
angle of the encoder for the
PMSM is correct.
•
Check the motor parameter setting
and perform motor auto-tuning.
•
Check the power cables of the
motor (refer to the solution of
Err02).
4A
Err11 Motor overload
•
FC-02 is set
improperly.
•
The brake circuit is
abnormal.
•
The load is too heavy.
•
Adjust the parameter (FC-02 can
be set to the default value).
•
Refer to the solution of Err10.
3A
Err12
Power supply
phase loss
•
The power input
phases are not
symmetric.
•
The drive control
board fails.
•
Check whether the three phases
of power supply are balanced
and whether the power voltage is
normal. If not, adjust the power
input.
•
Contact the agent or Monarch.
