7 A Three-Phase Stepper Drive for Open-Loop Motion

The 3DM3722 is a three-phase stepper drive rated for up to 7.0 A of output current from an 80-230 VAC supply. It is designed to drive 3-phase stepper motors in open-loop systems where a controller issues step and direction signals.

Control Interface

The drive accepts standard Pulse/Dir and CW/CCW pulse modes, so it integrates directly with CNC controllers and PLC pulse outputs. Because operation is open-loop, no encoder feedback or tuning loop is required, which shortens commissioning on multi-axis machines.

Protection and Smoothing

Integrated overcurrent, overvoltage, and undervoltage protection guard the drive and motor against supply and wiring faults. The output stage is tuned for low noise and vibration, producing smooth stepper motion that reduces mechanical stress on the axis.

Applications

It is suited to Factory Automation, Packaging Machinery, Compact CNC Equipment, Robotics, Automated Handling Mechanisms, Textile Machinery, Printing Machinery, and Food Processing.

  • Output current: max 7.0 A
  • Supply voltage: 80-230 VAC
  • Control modes: Pulse/Dir, CW/CCW pulse
  • Protection: overcurrent, overvoltage, undervoltage
  • Operation: open-loop, low noise and vibration

System Selection

Match the drive to a 3-phase stepper motor whose per-phase current falls within the 7.0 A capacity. The wide AC supply range supports both 110 V and 220 V line regions without extra hardware.
