n MM footprint: Extremely compact size with an industry standard mounting footprint.
n 4Q reversing: Regenerative/4 Quadrant drives have the ability to perform quick, contactorless reversing on-the-fly!
n Speed range and regulation: 1% regulation over 50:1 speed range.
n User adjustable calibration pots: IR compensation, max speed, forward current limit, reverse current limit and
forward acceleration (reverse deceleration), reverse acceleration (forward deceleration).
n Stopping modes: The user can decelerate (N.O.), regeneratively brake (N.O.), or coast motor to a stop (N.C.).
n Spade terminals: Easy to use, lower cost, and able to fit in a smaller package.
n Options and accessories: 201-0024 inhibit plug with 18” leads for regenerative brake option and 200-0386 limit switch
logic board.
n -PCM option: Add a “-PCM” to the end of the part number to receive the drive with an isolation transformer daughter
card. Drive will then be able to follow a -10 to +10V signal for variable speed control.
The MMRG Series, is one of the smallest full-wave four-
quadrant drives on the market today. These full-featured,
compact drives match brush-type DC motors ranging
from 1/20 to 2 Hp.
The MMRG Series provides all the performance of a full
size, four quadrant, regenerative variable speed drive
and has our popular MM23001 footprint (3.72” x
4.42”). This drive will maintain motor speed with
smooth motoring and braking torque, and allow high-
duty cycle reversing and braking. It has an adjustable
current limit, 1% of base speed regulation, and can reg-
ulate within a 50:1 speed range (open loop).
