9 Common problems and Solutions
Fault phenomenon Possible causes Treatment method
Motor does not rotate
Driver alarm Follow the alarm instructions
There is a stop command Provide motor operation command
Abnormal wiring Check wiring (including wire sequence)
The holding brake of the
motor is not opened
Open the motor holding brake
Motor drive mismatch The driver only supports motors with a Hall electric angle of 120 °
Equipment damage Replace the drive or motor
Motor overheating
Overload
Reduce load
Excessive limiting current
Reduce limiting current
Ambient temperature is
too high
Strengthen environmental heat dissipation
wiring error Correct wiring
Equipment damage Replace the drive or motor
Abnormal motor speed
Overload Reduce load
Abnormal signal input Check input signal
Wrong pole pairs Correct the pole pairs
Wrong reduce ration Calculate using the correct reduction ratio
Wrong setting maximum
speed
Set the maximum speed to the rated speed of the motor actually
used
Abnormal noise during
motor operation
wiring error Correct wiring
Motor drive mismatch The driver only supports motors with a Hall electric angle of 120 °
Lack of phase Please check the motor wiring
Load problem Motor test without load
Motor problem Replace the motor
Normal noise
Driving chopper noise and motor commutation noise are
normal
Motor speed
fluctuation
Abnormal signal input Change to internal speed regulation experiment
overload inertia reduce load or add reducer
Unstable load Maintaining a steady load or normal condition
No output signal
pull-up resistor is not
connected
Connect appropriate pull-up resistors to the alarm output
interface and speed output interface
Normal condition
Artificially create alarm or rotate the motor to check the
signal output
