20 ~ 60V Hybrid Stepper Motor Driver With Overheated Protection

Descriptions
The CW250 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.
Supply voltage range from 20VDC to 60VDC, suitable for driving various 2-phase hybrid stepping motors which phase current below 5A. The micro-step can be set from full step to 51200steps/rev and the output current can be set from 1.2A to 5.0A; with automatic idle-current reduction, self-test, over-voltage, under-voltage and over-current protection.
Features

  • High-performance, low price
  • micro-step
  • Automatic idle-current reduction

l Optical isolating signal I/O

l Max response frequency up to 75Kpps

  • Low temperature rise, smooth motion
  • Online adaptive PID technology

Applications
Suitable for a variety of large-scale automation equipments and instruments. For example: labeling machine, cutting machine, packaging machine, plotter, engraving machine, CNC machine tools and so on. It always performs well when applied for equipment which requires for low-vibration, low-noise, high-precision and high-velocity.

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.
Micro-step Setting
The segment for CW250 is fixed to 8.
