Power interface :

1.Motor  driver U.V.W. Connect with stepper motor , (1.3.5) terminal . 2.Motor  driver L,N connect AC 220V .
3.Motor  driver PE ,protect grounding .


Control signal :

 






 Malfunction analysis :


Power: power supply instruction .
 Ready: motor  driver work normally ,green light turn on ;if motor driver  work abnormally,green light will  not turn on .
 Fault: Malfunction or short circuit between two  phase happen ,error red light turn on .
 Temp:   when the temperature of radiator is over 75? and light light,Temp is  overheating .
 Over: when the  output voltage is larger than 410V , it is over-voltage.
 Low:   when the input voltage is smaller than 150V  , it is under-voltage .
 Over + Low:light at the same  time,door/enable  function is valid,Over + Low don’t light /enable function is invalid .

Malfunction analysis

Malfunction	Cause	Action
Power    don’t light	power supply voltage is low	Test the voltage of power supply
	Voltage    of power supply connect wrongly	Test    the connection of power supply
stepper motors don’t rotate    and no holding torque	Input current signal work	make the input signal don’t work
	Wrong wire connection of stepper motor	do the correct connection
stepper motor don’t rotate but with holding    torque	Door signal work	make the input signal work
	Input Pulse signal	Adjust the PWM and signal level
Stepper motors rotate irregularly	Input pulse and direction signal	Adjust the PWM and signal level
	Over-loading	Reduce the loading
	Malfunction of stepper motor	Change the stepper motor
Wrong rotation direction of stepper motor	wrong phase wire connection	change the random phase wire
	input direction signal setting is wrong	change the direction    setting
holding torque is too small	the setting of phase current is too low	Adjust the setting of phase current
Much noise of stepper motor	Malfunction    of stepper motor	Change    the stepper motor
Ready light is red	location of enable switch is wrong	check    whether the setting of enable switch is correct
	Signal wire is bad	check whether signal wire is ok
	signal wire is no signal	check whether the wire have signal
Fault light is on	Phase short circuit	connect the correct the motivation wire of stepper motor
	signal wire or driver wire    is bad	Correct the connection
	Pulse is with interference or the frequency of the pulse is too    high	check the signal wire or    low the pulse frequency
Temp lit	Radiator temperature >75ºC	check the setting of phase current
		check whether the fan of    motor driver work
Over light is on	Output voltage > 410V	check the input voltage of power supply
Low light is on	Input voltage < 150V	check the input voltage of power supply
Over and Low light is on at the same time	No enable signal	check the enable setting switch
