2-Phase Digital Hybrid Stepper 

Product Description

Stepper Motor Driver Specification



The DM542 is a new generation microstep stepper motor driver. Due to the adoption of the advanced bipolar constant-current chopper driver technology, it shows stable operation, provides excellent high torque. Moreover, it significantly reduces the noises and vibration of the operating motor. The DM542 has the feature of low-noise, low-vibration and low-heating. The DM542 is DC18-50V power supply. It applies to 2-phase hybrid stepper motor under 4.2A current The DM542 has 15 kinds of microsteps. The maximum step number is 25600 steps/rev (microstep is 1/128). The peak operating current ranges from 1.0A to 4.2A., and the output current has 8 stalls. The DM542 has automatic semi-flow, motor misconnected , over-voltage, under-voltage, and over-current protection functions.



1. Adopted 32-bit DSP, pure sine ware subdivision technology
2. Low-noise, low-vibration and low temperature rising (with fan)
3. Voltage18-50VAC    
4. With 8 stalls output current setting, peak current 4.2A 
5. With  15 stalls microstep subdivision setting  
6. Automatic half current, self-test, over voltage, under voltage, over current protection
7. Internal optical isolation, highest frequency response 200KHZ
8. Suitable for current range 1.0-4.2A; 2, 4 phase Nema 23, Nema 34 hybrid stepper motor


 It can be applied in a variety of small scale automation equipment and instruments, such as labeling machine, cutting machine, packing machine, drawing machine, engraving machine, CNC machine and so on. It always performs well when it is used in equipment which requires for low-vibration, low-noise, high-precision and high-velocity.
