5.2 Common Faults and Solutions
The following faults may occur during the use of the servo drive. Refer to the following table
for simple fault analysis.
SN Fault Possible Causes Solutions
1
No display upon
power-on
There is no power supply to
the servo drive.
The 8-core cable connecting
the drive board and control
board is in poor contact.
The servo drive's internal parts
are broken.
Check the power input.
Re-connect the 8-core cable.
Contact the agent or our
company.
2
"HC" is displayed
upon power-on.
The 4-core cable connecting
the drive board and the control
board is in poor contact.
Other parts of the servo drive
are broken.
Re-connect the 4-core cable.
Contact the agent or our
company.
3
"Err23" is displayed
upon power-on.
The motor or the motor output
cable is short circuited to the
ground.
The servo drive is damaged.
Measure the insulation of the
motor and the output cable
with megger.
Contact the agent or our
company.
4
The servo drive
display is normal
upon power-on.
But it displays "HC"
after running and
stops immediately.
Cooling fan is broken or does
not rotate.
Replace the cooling fan.
5
Err14 (module
overheat) is
reported frequently.
The setting of carrier frequency
is too high.
Cooling fan is broken, or the
air filter is clogged.
The internal parts (thermal
coupler or others) of the servo
drive are damaged.
Lower the carrier frequency
(F0-15).
Replace the cooling fan and
clean the air filter.
Contact the agent or our
company.
6
The motor does
not rotate after the
servo drive runs
The motor is broken or
clogged.
The parameters are set
improperly (motor parameters
in group F1).
Replace the motor or clear
mechanical faults.
Check and re-set motor
parameters.
7 DI terminal disabled
The parameter is set wrongly.
The jumper across OP and
+24V becomes loose.
Control board is faulty.
Check and reset the group F4
parameters.
Re-connect the cables.
Contact our company.
8
In closed-loop
vector control, the
motor speed is
always low.
The encoder is broken or the
encoder wiring is wrong.
The servo drive's internal parts
are broken.
Replace the encoder and
ensure the cabling is proper.
Contact the agent or our
company.
