RG500UA-PCM DC Motor Control

RG500 Series

Minarik Drives' RG500UA-PCM consists of a full-wave, four-quadrant regenerative SCR drive that provides smooth motoring and braking torque for brush-type DC motors from 1/8 through 2 HP, for a single or bi-directional variable speed, without using mechanical contactors.

Slide switches allow the RG500UA drive to accept a 115 or 230VAC input to run 90 or 180VDC motors. The tach feedback mode virtually guarantees constant set speed under varying load. Applications with overhauling loads, rapid deceleration, basic positioning and high duty cycle reversing and braking benefit from this versatile regenerative drive.

Potentiometer Kit 202-0003 is included with a purchase of the RG500UA-PCM

  • 4Q Reversing: Regenerative/4 Quadrant drives have the ability to perform quick, contactorless reversing on-the-fly!
  • Speed range and regulation: 1% regulation over 50:1 speed range. 0.1% regulation over 60:1 speed range with the addition of a tachometer for feedback.
  • User adjustable calibration pots: IR compensation, forward torque, reverse torque, tachometer, min speed, max speed, forward acceleration, reverse acceleration and deadband.
  • Stopping Modes: User can decelerate (N.O.), regeneratively brake (N.O.) or coast to a stop (N.C.). User can also decelerate to min speed (N.O.)
  • Cage clamp terminal block: Quick and easy wire terminations.
  • On board fusing: No need to add external fusing for protection of your motor or drive.
  • Additional features:Dual voltage AC input, switch selectable armature or tachometer feedback mode and field supply for shunt wound motors.
  • Options and accessories: -201-0024 inhibit plug for regenerative brake option, 200-0386 limit switch logic board and DLC600 digital controller.
