Feature: 1. Reliable Material: Digital stepper motor driver is made of ABS material, which is high impact resistance and extrusion resistance, strong stability, not easily deformed by high temperature treatment. 2. Stepper Control Technology: By implementing advanced stepper control technology, this stepper drive is able to power 4 phase and 8 phase stepper motors smoothly with optimal torsion and low motor heating and noise. 3. Fast Heat Dissipation: Excellent heat dissipation performance drive base using proven spade tooth (aluminum extrusion) heat dissipation technology, even in a small installation space to maintain better heat dissipation performance, conducive to extending the life of the motherboard electronic components. 4. Strong Performance: Digital stepper motor driver has built in high segmentation, optional dialing, and external alarm output. With overvoltage, short circuit, and other protection functions. 5. Easy to Install: The DM556T is a digital stepper drive with simple design and easy setup, which is convenient for your work. Side mounting is recommended for better heat dissipation. When designing the installation, the size of the terminals and the space required for heat dissipation should be considered.
