RG61U-4S DC Motor Control


Minarik’s full-featured RG61U regen drive remarkably fits in the industry standard “MM” footprint. Mounted on a gold extruded chassis, the RG61U is ideal for high duty-cycle applications. 
Enable and Inhibit terminals are standard on the RG61U, along with the option to invert their functions. The invert jumpers let the customer decide whether the drive runs or stops when terminals are opened or closed. The eight combinations to choose from provide tremendous application flexibility.
The new robust design of the RG61U enables it to withstand a 1G vibration test, making it an excellent choice for demanding applications!

  • MM footprint: Extremely compact size with an industry standard mounting footprint.
  • 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% over 60:1 speed range with the addition of a tachometer for feedback.
  • User adjustable calibration pots: IR compensation, max speed, min speed, forward acceleration, reverse acceleration, forward torque, reverse torque, tachometer and deadband.
  • Diagnostic LEDs: Power, forward current limit, reverse current limit
  • Stopping modes: The user can decelerate (N.O.), regeneratively brake (N.O.) or coast the motor to a stop (N.O. and N.C.).
  • Spade terminals and cage clamp terminal block: Quick and easy wire connections
  • Configurable enable and inhibit: Can be configured to be either normally open or normally closed
  • Additional features: Tachometer feedback, gold extruded chassis and plastic capped trimmer pots
  • -PCM option: Add a –PCM to the end of the part number to receive the drive with an isolation daughter card for receiving non-isolated speed reference voltages between –10V and +10V
