Fault Handling

Fault Phenomenon	Solution
Red light is constantly on or flashes once every 3 seconds	Driver overcurrent alarm, check if the motor wires have issues, or disconnect the motor wires and power only the driver. If the fault persists, the driver has an internal fault and needs to be returned for repair.
Red light flashes continuously 2 times	Driver overvoltage alarm, check if the input voltage is within the power supply range
Red light flashes continuously 3 times	Driver undervoltage alarm, check if the input voltage is within the power supply range
Red light flashes continuously 4 times	Motor phase loss alarm, the driver motor wire may be disconnected, needs to be returned for repair
Red light flashes continuously 7 times	Position deviation too large alarm, check if the speed is too fast or if the motor is stalled
Red light flashes continuously 8 times	EEPROM storage failure, try initializing parameters and restarting. If the alarm persists, return for repair.
Red light flashes continuously 9 times	Homing timeout alarm, check if PA_055 is 16515.
Red light flashes continuously 10 times	Homing error alarm, check homing parameters and sensor switch, reset alarm and re-home.
Motor is enabled normally but cannot trigger operation	Use control word to trigger emergency stop, then check if internal position parameters are set incorrectly, then try to trigger position operation again.
Motor is making whining noise	1. Set PA_006 to 0, then restart the driver; 2. Reduce PA_009 and PA_010; 3. Reduce PA_011 and PA_013.
Motor is oscillating back and forth	Check if load inertia is too large, increase deceleration time
