CWDS556 Closed Loop Stepping System Introduction Descriptions CWDS556 is a new generation hybrid servo driver, it combines the advantage of the servo system and stepper system，the system acts as nothing more than a high pole servo motor, the classic stepper motor noises and resonances vanish. Because the position is controlled, the motor can also no longer lose any steps up to its maximum torque. Features Closed-loop control, no longer lose any steps, up to its maximum torgue; higher torque and higher speed; Fast response; Reduced motor heating and more efficient; Zero-speed stability; Smooth motion and super-low motor noise; No Tuning and always stable; Lower cost. Applications CWDS556 is a low-cost, high-performance servo systems, suitable for a variety of large-scale automated equipments and instruments, such as low-cost, low vibration, noise, high-precision, high-speed devices, And it is ideal for applications where the equipment uses a belt-drive mechanism or otherwise has low rigidity and you dont want it to vibrate when stopping. Electrical Specifications Parameter Min Typical Max Unit Input Voltage(DC) 20 - 50 VDC Output Current 0 - 5.6 A Pulse Signal Frequency 0 - 200 KHZ Logic Signal Current 7 10 16 MA Microstep and Dir Setting Steps/Revolution： Step/Rev SW1 SW2 SW3 SW4 Default on on on on 800 off on on on 1600 on off on on 3200 off off on on 6400 on on off on 12800 off on off on 25600 on off off on 51200 off off off on 1000 on on on off 2000 off on on off 4000 on off on off 5000 off off on off 8000 on on off off 10000 off on off off 20000 on off off off 40000 off off off off Motor Direction (SW5) Motor Direction SW5 ON OFF Direction Motor direction is positive Motor direction is negative 3.
