RTA - PLUS E4 - Boxed, Stepping Motor Drive

Stepping motor drive boxed PLUS E4
( 55 - 100 VAC 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 .
  • Optimized for driving R.T.A. EM series stepping motors with encoder (86 mm and 60 mm flange sizes).
  • Target: applications requiring EM stepping motors. Control in a standard way ("OPEN LOOP”) but also give an alarm in case of loss of synchronism ("CLOSED LOOP”).

HIGHLIGHTS

  • Microstepping function up to 4.000 step/rev.
  • Setting of the sensitivity of the loss of synchronism alarm system.
  • 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.
Technical Specifications
  • Version: drive housed in a metallic box 152 x 129 x 46 mm, equipped with plug-in connectors.
  • Range of operating voltages: 55 - 100 VAC.
  • Range of current: 1.9 - 6.0 Amp. Setting up to eight possible values by means of a dip-switch.
  • Microstepping: 400, 800, 1.600, 3.200 and 500, 1.000, 2.000, 4.000 steps /revolution. Setting by means of dip-switches.
  • Automatic current reduction at motor standstill.
  • Protections:
    - Protection against under-voltage and over-voltage.
    - Protection against a short-circuit at motor outputs.
    - Overheating protection with thermal sensor.
  • High efficiency CHOPPER with MOSFET final stage output.
  • Electronic damping facility for further acoustic noise and mechanic vibrations reduction at low and medium speed
  • Alarm memory by use of yellow blinking led.
  • Warranty: 24 months.

MOTOR LOSS OF SYNCHRONISM CONTROL FUNCTION

  • Input for the connection of the R.T.A. motors EM series encoder (NEMA 34 and 60 mm flange size).
  • Output for the loss of synchronism alarm.
  • Setting, by means of dip-switch, of the sensitivity of the loss of synchronism alarm system.
