Product: STEPPERONLINE CNC Stepper Motor Driver 1.0-4.2A 20-50VDC 1/128 Micro-Step Resolutions for Nema 17 and 23 Stepper Motor
Brand: STEPPERONLINE
Overview: 

 This driver is an industrial-grade fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. 
 Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. 
 Compared with other analog or TB6600 chips driver, it can drive a stepper motor at much lower noise, lower heating, and smoother movement. 
 
 Key Features: 

 * Anti-Resonance provides optimal torque and nulls mid-range instability
 * Motor auto-identification and parameter auto-configuration when power on, offer optimal responses with different motors
 * Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
 * 15 selectable microstep resolutions: 1/2, 1/4, 1/5, 1/8, 1/10, 1/16, 1/20, 1/25, 1/32, 1/40, 1/50, 1/64, 1/100, 1/125, 1/128
 * Soft-start with no “jump” when powered on
 * 8 selectable peak current including 1.00A to 4.20A
 * Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
 * Automatic idle-current reduction
 * Suitable for 2-phase and 4-phase motors
 * Support PUL/DIR mode
 * Over-voltage and over-current protections
