DV3722 Three‑Phase Stepper Motor Driver 80-290VAC 4-10A
The DV3722 is a DSP‑controlled, three‑phase hybrid stepper driver designed for NEMA 23–57 motors, accepting AC 80 – 290 VAC and providing 4.0 A – 10.0 A peak current (set by SW1–SW4). It delivers ultra‑smooth torque with selectable microstepping from 400 to 60,000 steps/rev via SW5–SW8, and supports both single‑pulse (PUL/DIR) and CW/CCW modes (SW9). An autorun option (SW10) enables standalone operation. Built‑in protections guard against over‑voltage, over‑current, and over‑temperature.
Features
- Wide AC input range 80 VAC – 290 VAC for flexible power sources.
- Configurable peak current 4.0 A – 10.0 A via SW1–SW4.
- Microstepping resolution from 400 to 60,000 steps/rev (SW5–SW8).
- Switchable control modes: CP/DIR or CW/CCW (SW9).
- Autorun or pulse‑input selection via SW10.
- DSP‑based current control for low noise and high torque.
- Protections: over‑voltage, over‑current, under‑voltage, over‑temperature.
- LED indicators for power and fault status.
