ST2405S Digital Stepper Motor Driver 20-50VDC 1.0-6.0A

Description

ST2405S Digital Stepper Motor Driver 20-50VDC 1.0-6.0A The ST2405S is a DSP-driven two-phase (bipolar) stepper motor driver designed for compact to mid-range NEMA steppers (typically NEMA 17/23). Operating on 20–50 VDC, it delivers configurable peak output current up to 6.0 A via eight selectable levels. Features include PI-control algorithm for low noise, vibration, and heat, selectable micro-subdivision (16 positions), optically isolated single-/dual-pulse inputs, and active idle-current reduction, providing smooth and accurate motion performance. Features Wide input voltage range: 20–50VDC. Peak output current up to 6.0A. Supports single-ended and differential pulse inputs. Microstepping resolution up to 25,600 steps per revolution. Advanced PI control algorithm for smooth and quiet operation. Built-in protections: over-voltage, under-voltage, over-current, and overheating. Compatible with NEMA 17 and NEMA 23 stepper motors. Compact design for easy system integration.
