RTA – A-CSD – 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 CSD 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 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.

Technical Specifications

• Version: open frame drive in 92 x 85 x 22 mm, equipped with AMP connectors.
• Range of operating voltages: 24-48 VDC.
• Range of current: 0.7-4.4 Amp. Setting up to eight possible values by means of a dip-switch.
• Microstepping: 400, 800, 1.600 and 3.200 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 reduction.
• Warranty: 24 months.
