DC ADJUSTABLE SPEED DRIVES
SCR CONTROLS
LEESON Speedmaster
®
DC controls are general purpose
drives designed for use with permanent magnet type direct
current motors. NEMA 1 enclosed drives are suitable for most
industrial applications, with the NEMA 4X enclosures best suited
for washdown or outdoor installations or for extremely dusty
applications. Chassis only units are available for building into
equipment, machinery or existing enclosures. Most controls have
a dual voltage switch allowing the control to be used on 115 or
230 volt, single phase, 50/60 Hertz service. However, the proper
voltage motor should be selected for use with the power supply
input, i.e., 90 volt DC motors for 115 volt input or 180 volt motors
for 230 volt input service. Installation and adjustment instructions
are included.
SCR/Thyristor
drives are available in unidirectional and electro-
mechanical type reversing styles for NEMA frame ratings and
sub-fractional HP sizes.
The MM23000D Difference
The MM23000D Series SCR drives are dual voltage (115 or 230 VAC)
and in the industry standard “MM” footprint (3.58” x 4.30”). NEMA 1
and 4X enclosures round out the MM23000D family.
This series is more resilient to vibration and comes with another
feature, a user-selectable inhibit circuit. The user can adjust the
function of the inhibit with jumper pins. The MM23000D Series drives
can inhibit with either open or closed contacts. They can also inhibit to
either minimum set speed or stop.
!LL -- $ 3ERIES DRIVES COME WITH ,%$S TO LET THE USER KNOW
when the power is on (green) or if the motor has reached the current
limit (red). For applications that require control of a DC motor in the
1/20 to 2 HP range, the MM23000D is an excellent solution.

Everything needed for driving a 90VDC brush motor with no frills.
Features
small footprint but standard mounting, 1% speed regulation, user easily sets min/
max speed, IR comp, current limit and accel/
decel. Requires a speed reference signal
from a wired 10K OHM potentiometer or a
0-6VDC isolated signal. Stop/start is available
through inhabit terminals causing motor to
coast to a stop; opening terminals causes
the motor to accelerate to set speed. Typical
applications: Conveyors, Materials Handling,
Packaging/Sorting/Printing and other OEM
machinery.
