DMC-30016 combines a single-axis motion controller with a 1.4-A per phase, 30-V stepper amplifier that drives a two-phase, bipolar stepper motor in full-, half-, 1/4- or 1/16-step. It is configurable at 0.5–1.4 A per phase in 10 mA increments at 12–30 Vdc. Servo loop update is 125 ms, encoder frequency is 15 MHz, and stepper pulse output is 3 MHz.
