Overview
The DM556 2-phase stepper motor driver is designed for 42/57 stepper motors in automation equipment. It uses bipolar constant-current PWM drive and supports a 20-50V DC input supply, with adjustable output current for motion-control installations such as automatic packaging and engraving machines.
Key Features
- Eight selectable output-current levels from 1.0A to 5.6A in 0.5A increments.
- Optically isolated signal input.
- Maximum pulse response frequency of 200kHz.
- Bipolar constant-current PWM drive method.
- Designed for low-speed, low-noise operation and interference-resistant positioning control.
