DM542 Motor Stepper Driver 4.2A 20 - 50V

Stepper motor Driver Controller DM 542

1. Introductions
The DM542 is a digital stepper drive with simple design and easy setup. By implementing Leadshine advanced
stepper control technology, this stepper drive is able to power 2-phase and 4 phase stepper motors smoothly with
optimal torque and low motor heating & noise. Its operating voltage is 20-50VDC and it can output up to 4.2A current.
All the micro step and output current are done via DIP switches. Therefore, the DM542 are ideal choices for
applications requiring simple step & direction control of NEMA 17, 23, and 24 stepper motors.
