RTA – A-NDC – Open-Frame, Stepping Motor Drive

Introduction

• Series of bipolar microstep stepping motor drives, specifically developed for applications sensitive to acoustic noise and vibration.
• Significant evolution of the NDC series, preserving backward mechanical, electrical and applicative compatibility.
• Target: advanced applications requiring high precision, smoothness of movement and low acoustic noise.

Highlights

• Full digital microstepping drive.
• Adaptive microstepping up to 12.800 step/rev (1/64).
• 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.
