DM556 ROHS 20VDC-50VDC Nema 23 Stepper Motor Driver 5.6A Smooth Motion
DM556 Supply voltage range from 20VDC to 50VDC, suitable for driving various 2-phase hybrid stepping motors which phase current below 5.6A. The micro-step can be set from full step to 25600steps/rev and the output current can be set from 2.1A to 5.6A; with automatic idle-current reduction, self-test, over-voltage, under-voltage and over-current protection.
The DM556 is a new generation digital 2-phase stepper motor driver, based on a 32-bit DSP processor, combination of the anti-resonance, low noise, micro-step and low temperature rise technology significantly improve the performance of the stepper motor, has low noise, small vibration, low temperature rise and high-speed torque. The driver use online adaptive PID technology, without manual adjustment can be automatically generated optimal parameters for different motors, and achieve the best performance.
Features:
- High-performance, low price
- micro-step
- Automatic idle-current reduction
- Optical isolating signal I/O
- Max response frequency up to 200Kpps
- Low temperature rise, smooth motion
- Online adaptive PID technology
Electrical Specifications:
| Parameter | Min | Typical | Max | Unit |

Standstill Current Setting:
SW4 is used for standstill current setting. OFF means that the standstill current is half of the dynamic current; and ON means that standstill current is the same as the selected dynamic current. Usually the SW4 is set to OFF, in order to reduce the heat of the motor and driver.
