4.8A 3-Phase Stepper Drive for Open-Loop Axes

4.8 A Three-Phase Stepper Drive

The 3DM3422 is a three-phase stepper drive providing up to 4.8 A of output current from a flexible 80-230 VAC supply. It is sized for 3-phase stepper motors in the light-to-medium torque class used across industrial motion control.

Command Handling

Supported Pulse/Dir and CW/CCW pulse modes allow direct connection to common CNC controllers. Open-loop operation removes the need for encoder feedback, so the drive runs deterministically on step count alone and requires no closed-loop tuning.

Reliability Features

Overcurrent, overvoltage, and undervoltage protection respond to wiring and supply faults before they can damage the motor. The drive output is tuned for low noise and vibration, giving smooth motion that keeps machinery quiet and protects delicate mechanical components.

Applications

The drive fits Factory Automation, Packaging Machinery, Compact CNC Equipment, Robotics, Automated Handling Mechanisms, Textile Machinery, Printing Machinery, and Food Processing.

• Output current: max 4.8 A
• Supply voltage: 80-230 VAC
• Control modes: Pulse/Dir, CW/CCW pulse
• Protection: overcurrent, overvoltage, undervoltage
• Operation: open-loop, low noise and vibration

Pairing Guidance

Select a 3-phase motor with a per-phase current at or below 4.8 A. The dual-range AC input simplifies deployment across different mains voltages.
