RTA - ADW 06.V - Open-Frame, Stepping Motor Drive

Stepping motor drive open-frame ADW 06.V (with Intelligent Speed Controller)
( 24 - 75 VDC 1.9 - 6.0 Amp ) with screw-type connectors


  • ADW is the new R.T.A. electronic drive designed for all applications where accurate SPEED CONTROL is needed.
  • The motor velocity can be regulated in 3 ways:
    - Analog voltage input
    - External potentiometer 
    - Internal speed settings
  • The extended ADW power range (24-75 VDC, 0.65 - 6.0 Amps) and its versatility (4 Modes of Operation) allow to access to a wide variety of application fields.


  • Any speed-regulated applications with variable or pre-set velocity setting.
  • Conveyors:
    - Single belt transport
    - Multi belt transport with high precision position/speed synchronization.
  • Jog or adjustment movements.

Technical Specifications

  • Version: open frame drive in 122 x 93.5 x 25 mm, equipped with screw-type connectors.
  • Range of operating voltage: 24-75 VDC.
  • Range of current: 1.9-6 Amp. Easy setting of values by means of a dip-switch.
  • Wide speed range: 0.8 rpm to 2,000 rpm. Continous operation zone up to approx 400 rpm, depending on motor choice.
  • 64 internally selectable preset speed.
  • 0-5Vdc or 0-10Vdc selectable analog command range.
  • Low & High-speed motion profile.
  • Adjustable internal acceleration/deceleration ramp.
  • Voltage source for potentiometer available at connector.
  • Auto-stop function.
  • All opto-insulated digital inputs.
  • Sync-out for multi-Axis synchronization.
  • Over-voltage, short-circuit and thermal protection.
  • Warranty: 24 months.


  • Broader and more accurate speed range [0.8 rpm to 2,000 rpm].
  • Zero-deviation motor speed control at any speed. [motor speed is not affected by variable factors like load, inertia or friction].
  • The motors automatically act as brake at zero speed.
  • Easy multi-axis synchronization in Position and Speed.
  • No need of worm gearbox due to the high-torque at low rotation speed range [0-400 rpm].
  • Smaller dimension: overall size < 1/3 compared with traditional AC Asynchronous sets.Lower weight.
