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.

Technical Specifications

  • Version: open frame drive in 101 x 94 x 25 mm, equipped with AMP connectors.
  • Range of operating voltages: 24-85 VDC.
  • Range of current: 0.6-6Amp. Setting up to eight possible values by means of a dip-switch.
  • Microstepping: 400, 800, 1.600, 3.200, 6.400 and 12.800 steps/revolution. Setting by means of dip-switches.
  • Automatic current reduction at motor standstill.
  • Management of the current profile setting by means of a dip-switch.
  • Protections:
    - Protection against under-voltage and over-voltage.
    - Protection against a short-circuit at motor outputs.
    - Overtemperature protection with thermal sensor.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reductions
  • Optoinsulated inputs compatible to ensure best EM noise immunity.
  • Warranty: 24 months.
