DC motor driver CWD556

low-voltagewith integrated controllertwo-phase stepper

Overview
The CWD556 is a compact digital 2-phase stepper driver based on a 32-bit DSP processor, designed for industrial motion control. It supports 20–50 VDC and output currents from 2.1 to 5.6 A, integrates anti-resonance control and an online adaptive PID for improved stability, and provides optically isolated control inputs for reliable operation in noisy environments.

Key Highlights

• 32-bit DSP processor with anti-resonance control
• Online adaptive PID algorithm for dynamic tuning
• Optically isolated control inputs (Pulse/Direction or CW/CCW)
• Low noise and vibration with low temperature rise
• 16 microstep settings up to 51,200 steps/rev
• Compact footprint: 118 × 75 × 34 mm, weight 0.3 kg
