Product Features

RD-323MS is a 2-phase Stepping Motor Driver that enables micro-stepping drive. Positioning control is available using the counter built-in I/O Master RC-208A because the pulse oscillator is built in.

  • Built-in pulse oscillator simply enables trapezoidal acceleration/deceleration operation.
  • Rotational speed can be set by the analog voltage.
  • Low vibration using high resolution micro-stepping.
  • Automatic current down circuit is used. (adjustable current value).
