Stepper Drive DM870: The Leadshine model DM870 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 20-75VDC and it can output up to 7.0A 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 2 phase & 4 phase NEMA 23, 24, and 34 stepper motors.
