The CW215 driver is a cost-effective and high performance stepping driver. The design is based on an advanced control technology. It applies to two-phase or four-phase hybrid stepping motor below 1.5A,such as 42BYG,39BYG. Due to the adoption of the advanced bipolar constant-current chopper driver technology. It shows many features such as stable operation and excellent high speed torque. It has 7 kinds of micro-step, and the maximum number of micro-step is 1/64. Chopping frequency of 20000 times per second can eliminate the noise of the motor. Another unique function is that it can automatically reduce current: when the motor is stopped, the output current reduces to a lower value, thereby reducing the heating of the motor and driver.

Supply voltage range from 18VDC to 40VDC ,the output current can be set from 0.2A to 1.5A; with automatic idle-current reduction, self-test, over-voltage, under-voltage and over-current protection.


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

l Optical isolating signal I/O

l Max response frequency up to 70Kpps

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


It is suitable for a variety of small-scale automation equipments and instruments, such as 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.
