DM542 Stepper Motor Driver 4.2A

Note: Please note that this driver is not suitable for industrial CNC machines which have high-power stepper motors.

Features:

1) Driver integrated overvoltage and overcurrent protection

2) Input signal light isolation

3) Bipolar constant current chopping mode

4) DC power supply 20-50VDC (24-48VDC recommended)

5) Maximum drive current 4.2A

6) Output current dial switch is adjustable

7) Low speed zero vibration with minimal noise

8) Strong anti-interference ability, high precision status in the harsh environment of the power grid

9) High reliability: Power devices have sufficient margin and are rigorously tested at the factory.

Pins:

1、 +V：DC Power positive terminal

2、 GND：DCPower negative terminal

3、 A+、A-：Stepping motor one winding

4、 B+、B-：Stepping motor other winding

5、 PUL+（+5V-24V）、PUL -：Stepping pulse input (Rising edge effective , Pulse width >1.2 us)

6、DIR +（+5V-24V）、DIR-：Direction signal input,highlevelforeward , lowlevelreverse, The direction of signal should be at least 5 us ahead of the pulse signal.

7、 ENA+（+5V-24V）、ENA-: motor free

8、 Green LED: Power LED

9、 Red LED : Fault indication, over current、overvoltage、or other failures. The red LED light is bright, after the failure is eliminated, Power off for a while and then power, the red LED lamp is out
