8 Troubleshooting
Phenomenon
Possible reason
Troubleshooting
Motor stop
Alarm
Do as alarm code
Press Stop
Press Start
Wrongly motor lines
Check the wiring and phase
Motor brake is wrong
Make sure the motor brake is open
Driver doesn’t match the motor
This driver only supports motors with a Hall electrical
angle of 120°
Damage
Replace new motor and driver
Over heat
Over load
Make the load lower
Over current
Make the current lower
The ambient temperature is too high
Improve environmental heat dissipation.
Wrong phase
Correct phase connection
Damage
Replace new motor and driver
Abnormal
motor speed
Overload
Make the load smaller
Signal input wrongly
Signal input checking
Wrong poles pairs numbers setting
Set the right poles numbers
Wrong gear ratio setting
Set the right gear ratio
Wrong max speed setting
Set the maximum speed to the rated speed of the actual
motor
The motor is
running with
abnormal
noise
Phase wrongly
Check the motor phase
Driver doesn’t match the motor
This driver only supports motors with a Hall electrical
angle of 120°
Lack of phase wiring
Check the motor phase
Load problem
No load operation motor test
Motor problem
Change the motor
Motor speed
fluctuations
Signal input wrongly
Change to knob speed setting to check if there is the
same error
The load inertia ratio is too large
Decrease load inertia ratio or increase gear box
The load is changeable
Steady load or this condition is normal
No signal
output
Pull-up resistor not connected
The alarm output interface and the speed output interface
are connected with appropriate pull-up resistors
