Stepping motor drive open-frame A-NDC 04 (ADVANCED)
( 24 - 85 VDC 0.6 - 2.0 Amp ) with AMP connectors


► New 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.


► 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.
►UL Recognized
