RTA – X-MIND – Boxed Stepping Motor Drive

Introduction

• Stepping motor drives series with Step & Direction interface and direct input from the main AC power supply (from 110 VAC to 230 VAC).
• The drive is equipped with an internal rectifier able to transfer more than 330 VDC (230 VAC) to the motor, to ensure the maximum power for the application as well as a significant cost saving on transformer and rectifier, together with the related cabling activity.
• Target: advanced application requiring great dynamic performance, high reliability and semplified power supply.
• UL/CSA certified.

Highlights

• Microstepping function up to 4.000 step/rev.
• Connection directly to the main AC supply (110 to 230 VAC) normally avoiding the need for a transformer.
• Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
• External fans not needed: ideal both for mounting inside a metallic electrical cabinet and for stand-alone applications.
• Optoinsulated and differential input and output signals ease interfacing with the most commonly used control systems and ensure high noise immunity.
• Coupling with stepping motors rated for high voltage and equivalent or bigger than NEMA 34 is mandatory.
