DM556 Stepper Motor Driver

Br 10,500.00

The DM556 is a versatile, fully digital 2-phase stepper motor driver (20-50VDC, up to 5.6A) designed for low-noise, high-precision motion in NEMA 23 and 34 motors. Using DSP technology, it supports 16 microstep resolutions up to 25,600 steps/rev, making it ideal for CNC routers, engravers, and automation.

DIP Switch Configuration (Typical)

Current Settings (SW1-SW3): Set based on motor rated current to manage heat.
Microstep Resolution (SW5-SW8): Defines pulses per revolution (e.g., 400 for 1/2 step, 1600 for 1/8 step, etc.).
Half Current (SW4): Enables auto-half current to reduce motor heating when stationary
