ST5-H Digital Stepper Motor Driver 18-65VAC/20-90VDC 2.8-7.0A
The ST5‑H is a DSP‑driven hybrid stepper driver engineered for two‑phase NEMA 23–34 motors. It accepts 18–65 VAC or 20–90 VDC and delivers 2.8–7 A peak output current, selectable in 16 levels via SW1–SW4. With 16 microstep resolutions from 200 to 25,600 steps/rev via SW5–SW8, automatic motor tuning, anti‑resonance smoothing, soft‑start, and idle‑current reduction, the ST5‑H ensures smooth, precise motion and minimal heat.
Features
- Configurable peak current 2.8–7 A in 16 steps via SW1–SW4.
- Selectable microstepping 200–25,600 steps/rev via SW5–SW8.
- Dual supply compatibility: 18–65 VAC or 20–90 VDC.
- DSP‑based auto‑tuning/self‑test on power‑up.
- Anti‑resonance filtering for stable mid‑speed torque.
- Soft‑start to prevent motor “kick” at power‑on.
- Idle‑current reduction (~50 %) after ~1 s inactivity.
- Opto‑isolated step/direction and CW/CCW inputs.
- Comprehensive protections: over‑voltage, under‑voltage, over‑current, phase‑open.
