RTA - A-CSD 04 - Open Frame, Stepping Motor Drive

Stepping motor drive open-frame A-CSD 04 ( ADVANCED )
( 24 - 48 VDC 2.6 - 4.4 Amp )


  • New series of bipolar microstep stepping motor drives, specifically developed for applications sensitive to acoustic noise and vibration.
  • Significant evolution of the CSD series, preserving backward mechanical, electrical and applicative compatibility.
  • Target: advanced applications requiring high precision, smoothness of movement and low acoustic noise.
  • Full digital microstepping drive.
  • Adaptive microstepping up to 3.200 step/rev.
  • Intelligent management of the current profile that achieves good results in terms of smoothness of movement, low noise and vibration control.
  • A highly sophisticated control system, preserving anyhow the traditional ease of use of R.T.A. drives.
