General Features: Micro Stepping Motor Driver for maximum current6A. It can use with AC power supply that the input voltage can receive from a transformer directly. The working input voltage is between 24VAC to55VAC




1. power input type:24V~55V AC

2.Output current:2~6A



4.Protect form : Overheated  protect, lock automatic half current ,error connect protect

5. Dimensions:147mm*97mm*30mm


7.Working environment:Temperature-15~40℃Humidity<90%。


I/O Ports

1、AC,AC:AC power positive pole 24V~55V AC

Note:Must guard against exceeding 55V AC,

so as not to damage the module

2、GND:DC power cathode

3、A+、A-:Stepping motor one winding

4、B+、B-:Stepping motor other winding

5、CP +、CP -:Stepping pulse input+5V (Rising edge effective , rising edge duration >10μS)

6、CW +、CW-:Stepping motor direction input, voltage level touched off,high towards, low reverse

7、REST+、REST-: motor free 


1, When ambient temperature is high or working current over 3A,  fix the module on big metal shell ,

or use axle flows fan dispels the heat, to make the module run reliably for a long time.

2,  Half current automatically: if control machine not send out signal  in half second,

driver enter half current state of automatically for electricity saving, the phase current of the winding

 of the electric

3, The fault phase is protected : When the double-phase electrical machinery is connected with driver ,

users are apt to connect the phase by mistake, thus would damage the driver seriously.

The protecting circuit is within this driver, when users connect by mistake, the driver will not be

damaged, but the electrical machinery runs abnormally, shake , and output is small.Please check

whether the wiring of electrical machinery is a mistake
