RTA - PLUS A4 - Boxed, Stepping Motor Drive

Stepping motor drive boxed PLUS A4
( 77 - 140 VDC 1.9 - 6.0 Amp )


Introduction

  • Stepping motor drives series with Step & Direction interface suitable for driving two-phase stepping motors, with four, six or eight terminals based on the following versions.
    -PLUS A3 and PLUS A4: with DC power supply (39-140 VDC)
    -PLUS B3, PLUS B4 and PLUS B7: with AC power supply (28-100 VAC)
  • Compact, easy to use and cost effective solution. This system is designed for mounting inside a metallic electrical cabinet. Suitable for wall mounting.
  • Target: medium and medium-high power applications requiring 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.
  • External fans not needed: ideal both for mounting inside a metallic electrical cabinet and for stand-alone applications.
  • Operation with built-in oscillator with speed range from 14 to 450 rpm setting by means of dip-switches.

Technical Specifications

  • Version: drive housed in a metallic box 152 x 129 x 46 mm, equipped with plug-in connectors.
  • Range of operating voltages: 77-140 VDC.
  • Range of current: 1.9 -6 Amp. Setting up to eight possible values by means of a dip-switch.
