Closed Loop 57 Stepper Motor Driver 18-90VDC 3-6A

Description

Closed Loop 57 Stepper Motor Driver 18-90VDC 3-6A The Closed‑Loop 57 is a high-fidelity driver that blends stepper simplicity with servo feedback precision. Powered by 18–90 VDC (nominally 24–48 VDC), it delivers 3–6 A peak current, selectable via DIP switches or RS‑232 interface. Featuring fully DSP-based closed-loop control, encoder feedback ensures zero-step loss, full torque utilization, and real-time position correction. Programmable microstepping from 400 to 51,200 steps/rev, auto-tuned PID loops, and robust protections reduce heating, noise, and vibration for smoother, more reliable motion. Features Closed-loop servo-grade control eliminates step loss and torque reservation Configurable peak current 3 – 6 A via DIP or software. Microstepping from 400 to 51,200 steps/rev via DIP or RS‑232. Wide 18–90 VDC input range for flexible power setups. Supports 5–24 V logic input, compatible with stepper controllers and PLCs. Auto PID tuning and self-test reduce setup time and guarantee optimal performance. Fault detection via encoder and protective LED indicators. Triple-layer protections: over‑voltage, over‑current, and position-follow error.
