Product Detail

MD-3008A

Characteristic :
1.use AC servo control theory , it adds full digital current loop control way .
2.The power amplifier max voltage can be up to 325V ,high speed rotation stepper motor still have output high torque .
3.With short circuit, over-voltage, under-voltage, over-temperature protection and improving functions .
4.With the function of subdivision .half current and power-down memory ability .

Many subdivision selection, control the precise location at any random condition , the min step angel can be set to 0.036° (1000steps/rev) .apply widely , by setting different phase current can be used with various motors .

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
Power don’t light	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
stepper motors don’t rotate and no holding torque	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
stepper motor don’t rotate but with holding torque	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
Wrong rotation direction of stepper motor	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
Temp lit	Radiator temperature >75ºC	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
