RTA - SAC 26 - Open Frame, Stepping Motor Drive

Stepping motor drive open-frame SAC 26
( 24 - 50 VAC 3.4 - 6.0 Amp )


Introduction

  • Series of ministep bipolar chopper drives, suitable for driving medium power two-phase stepping motors, with four, six or eight terminals.
  • Compact, easy to use and cost effective solution. This system is designed for easy mounting inside a metallic electrical cabinet.
  • Equipped with power supply and particularly suitable for stand-alone applications (AC input).
  • Target: medium and medium-low power applications without special configuration requirement, but needing great dynamic performance, high reliability, low acoustic noise and mechanic vibrations reduction .

HIGHLIGHTS

  • Microstepping function up to 4.000 step/rev.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
  • Separated connectors for logic signals and power connections.
  • Optoinsulated and differential input and output signals ease interfacing with the most commonly used control systems.

Technical Specifications

  • Version: open frame drive in 101 x 125 x 35 mm, equipped with AMP connectors.
  • Range of operating voltages: 24-50 VAC.
  • Range of current: 3,4 -6,0 Amp. Setting up to four possible values by means of dip-switches.
