## INTRODUCTION 

- m 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. 

## HIGHLIGHTS 

- w Full digital microstepping drive. 

- = Adaptive microstepping up to a 3.200 step/rev. 

- m 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 traditionalease of use of R.T.A. drives.
