ST2-Plus Digital Stepper Motor Driver 12-50VDC 0.1-3.0A

Description

ST2-Plus Digital Stepper Motor Driver 12-50VDC The ST2‑Plus from is a high-precision digital driver for NEMA 11–17 hybrid stepper motors. It operates on 12–50 VDC and offers 0.1–3.0 A peak output current via SW1–SW4 DIP switches. Equipped with auto motor identification and tuning, anti-resonance smoothing, soft-start, idle-current reduction, and 16-position microstep selection up to 25,600 steps/rev, the ST2‑Plus ensures smooth, stable motion with reduced vibration and heat. Features Wide input voltage range: 12–50VDC. Peak output current up to 3.0A. Advanced microstepping up to 1/256 step resolution (51,200 pulses per revolution). Optically isolated STEP and DIR inputs supporting up to 200kHz pulse frequency. Idle current reduction to minimize power consumption. Comprehensive protection features: over-voltage, under-voltage, over-temperature, and short-circuit. Compact design for easy system integration.
