Autonics MD5-HF14

Autonics MD5-HF14 

Overview

The Autonics MD5-HF14 is a high-performance 5-phase stepper motor driver built for precise motion control in industrial automation systems. It uses a bipolar constant current pentagon drive method to ensure smooth, accurate movement with reduced noise and vibration. Designed for AC power input (100–220 VAC), it delivers up to 3 A output per phase and supports multiple step resolutions, making it ideal for robotics, semiconductor equipment, and precision positioning systems.

Key Features

• Bipolar constant current pentagon drive method

• Microstepping support up to 250 divisions (from 0.72° to 0.00288° per step)

• Auto current down function minimizes motor heating when idle

• Self-diagnosis (TEST mode) for driver and motor health checks

• Photocoupler-insulated inputs for improved noise immunity

• Compatible with 100–220 VAC power supply

• Chassis-mount design for easy installation

• Optional alarm output version (MD5-HF14-AO)
