The DM542E 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 DM542E are ideal choices for applications requiring simple step & direction control of NEMA 17, 23, and 24 stepper motors.
