Digital Stepper Driver 3022 0.3-2.2A 18-30VDC for Nema 8, 11, 14, 16, 17 Stepper Motor

In stock
On request


This is a digital stepper drive implemented with advanced stepper control technology. It is easy to use and it can be used to drive 2-phase and 4-phase motors(from Nema 8 ~ Nema 17 size) smoothly with less heat and noise. It works with 18-30VDC voltage and can provide max 2.2A peak current. You can set the DIP switches to get the current and microsteps you need.


  • Anti-Resonance for optimal torque, extra smooth motion, low motor heating and noise
  • Motor auto-identification and parameter auto-configuration for optimal torque from wide-range motors
  • Step & direction (PUL/DIR) control
  • Multi-Stepping for smooth motor movement
  • Optically isolated inputs
  • Input voltage 18-30VDC
  • 8 selectable micro-step resolutions of 400-12800 via DIP switches
  • 8 selectable output current settings of 0.3 – 2.2A via DIP switches
  • Soft-start with no “jump” when powered on
  • Pulse input frequency up to 60 KHz
