Instructions For Use:	The cnc driver drives the servo motor.The driver needs to select a power supply according to its self voltage range to power the driver, and then connect the driver with the servo motor, and the control system, the control system will control machine running.

phenomenon	Possible problem	solution
The motor does not rotate	Power light is off	Working normal
	Current setting is too small	According to the rated current of the motor, select the appropriate current gear
	Drive is protected	After the fault is excluded, power on again
	Enable signal is low	This signal is pulled high or not connected
	Wrong connection of motor wire	Arbitrarily exchange two wires of the same phase of the motor (for example, A + A- exchange wiring position)
Wrong direction of motor rotation	Motor wire is broken	Check and connect
Wrong direction of motor rotation	Wrong connection of motor wire	Check wiring
Alarm indicator light	Wrong connection of motor wire	Arbitrarily exchange two wires of the same phase of the motor (for example, A + A- exchange wiring position)
	The voltage is too high or too low	Check the power supply voltage
	Damaged motor or driver	Replace motor or driver
Inaccurate location	Signal is disturbed	Eliminate interference
	Shielded ground wire is not connected or not connected	Reliable ground
	Segmentation error	Set subdivision correctly
	Current is too small	Increase the current appropriately
	Control signal problems	Check whether the control signal meets the timing requirements
Stall when the motor accelerates speed	The acceleration time is too short	Increase the acceleration time appropriately
	Motor torque is too small	Choose high torque motor
	Low voltage or too low current	Properly increase the voltage or set a larger current
