RTA – X-PLUS – Boxed, Stepping Motor Drive

  • 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, in order to ensure the maximum power for the application as well as a significant cost saving on transformer and rectifier, together with the related cabling.
  • Target: advanced application requiring great dynamic performance, high reliability and simplified power supply.

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, in order to ensure the maximum power for the application as well as a significant cost saving on transformer and rectifier, together with the related cabling.
  • Target: advanced application requiring great dynamic performance, high reliability and simplified power supply.
Highlights
  • Microstepping function up to 3.200 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.
  • Coupling with stepping motors rated for high voltage and equivalent or bigger than NEMA 34 is mandatory.
Technical Specifications
  • Version: drive housed in a metallic box 152 x 129 x 30 mm, equipped with plug-in connectors.
  • Range of operating voltages: 110-230 VAC.
  • Range of current: 1.4 - 2.5 Amp. Easy setting of values by means of dip-switch.
  • Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of dip-switch.
  • Automatic current reduction at motor standstill.
  • Protections:
    -Protection against under-voltage and over-voltage.
    -Protection against a short-circuit at motor outputs.
    -Overtemperature protection with thermal sensor.
  • Optoinsulated inputs compatible with differential control signals.
  • Possibility to switch off motor current with an external logic signal.
  • High efficiency CHOPPER.
  • Electronic resonance damping circuit to ensure acoustic noise and mechanic vibrations reduction at low and medium speed.
  • Alarm memory by use of yellow blinking led.
  • External fans not needed.
  • Coupling with stepping motors rated for high voltage and equivalent or bigger than NEMA 34 is mandatory.
  • Warranty: 24 months.
