RTA - NDC 94 - Boxed, Stepping Motor Drive

Stepping motor drive boxed NDC 94
( 24 - 75 VDC 0.6 - 2.0 Amp ) with Plug_in connectors

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.
  • 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: drive housed in a metallic box in 110 x 108 x 34 mm, equipped with plug-in connectors.
  • Range of operating voltages: 24-75 VDC.
  • Range of current: 0.6-2 Amps. Setting up to eight possible values by means of a dip-switch.
  • Microstepping: 400, 500, 800, 1.000, 1.600, 2.000, 3.200 and 4.000 steps/revolution. Setting by means of a 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 with MOSFET final stage output.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed.
  • Available a version with built-in oscillator, with speed range from 14 to 450 rpm. Setting by means of dip-switches.
  • Warranty: 24 months.
