Possible reason
Module damaged or
undervoltage
Module damaged or
undervoltage or the
phase line is
short-circuited
Module the heat
dissipation is
abnormal (the cooling
fan does not rotate)
Power voltage is too
high
Power voltage is too
low
Encoder abnormality
or poor contact
Encoder abnormality
or poor contact
Encoder abnormality
or poor contact
Motor phase wires
are not connected or
have poor contact
Bleed Resistor Load
Exceeds Limit
Motor load exceeds
limit
Recommended action
Restart the machine, if it still cannot be
recovered, it is recommended to replace the
Motor Control module
Turn off the power and check whether the
input power line and phase line are connected
properly, and ensure that the motor phase line
is not short-circuited. If the fault is still
reported after restarting, it is recommended to
replace the electronic control module
First turn off the power and let it stand for a
period of time (cooling for heat dissipation). If
the fault is still reported during use after
restarting the machine,check whether the fan
connection is normal; if the fan rotates
normally and the fault is still reported during
use after restarting the machine, it needs to be
replaced Motor Control module
Power off, re-plug the power cord (check the
power supply voltage)
Power off, re-plug the power cord (check the
power supply voltage)
Power off, re-plug the encoder wire
(reinforced interface)
Power off, re-plug the encoder wire
(reinforced interface)
Power off, re-plug the encoder wire
(reinforced interface)
Power off, check whether the motor phase
wires are connected properly
Power off, wait for the machine to cool down
Power off, wait for the machine to cool down
