Control Device:Stepping Motor & Driver



Product Features

RD-024MSB is a 2-phase Stepping Motor Driver that enables the micro-stepping drive. Positioning control by the pulse string signals from Generate Master RC-234 is available.

  • Max. 50 V DC supply enables high speed operation.
  • New circuit method largely reduces heat generation more than existing products in spite of being high output.
  • Low vibration using high resolution micro-stepping.
  • All signal input/output circuits are insulated using photo-couplers.
  • Switching between 2-clock method and one clock method is available.
  • Automatic current down (adjustable current value).
