DESCRIPTION
The MDrive NEMA 23 high torque
Integrated Motor and Driver is
ideal for designers who want the
simplicity of a motor with on-board
electronics, but without the ex-
pense of an indexer on each axis.
The low cost MDrive23 allows the
system designer to decide the best
method of control. The MDrive23’s
integrated electronics eliminate
the need to run the motor cabling
through the machine, reducing the
potential for problems due to elec-
trical noise.
The MDrive23 uses a NEMA 23
frame size 1.8° high torque step-
ping motor combined with a mic-
rostepping driver, and accepts up
to 14 resolution settings from ½
to 256 microsteps per full step.
Setup parameters include Micro-
step Resolution, Motor Run/Hold
Current, and Motor Direction with
respect to the direction input.
These settings may be changed
on-the-fly or downloaded and
stored in nonvolatile memory with
the use of a simple GUI which is
provided. This eliminates the need
for external switches or resistors.
Parameters are changed via an
SPI port. Operating voltage for the
MDrive23 ranges from +12 to +48
VDC or +24 to +75 VDC.
The versatile, compact MDrive23 is
available in multiple configurations
to fit various system needs. These
include a single shaft rotary mo-
tor, a dual shaft rotary motor
available with optical encoder or
control knob, a planetary gearbox,
or a long life Acme screw linear
actuator. The rotary MDrive23 is
available in single, double and triple
stack sizes: 18, 22 & 31. Interface
The IMS Motor Interface GUI simplifies MDrive
configuring with a single screen interface.
(DIR feature with C Connector version only.)
connections are accomplished us-
ing either a 12 position keyed and
locking pin and receptacle (C Con-
nector), a 7 position terminal strip,
or 12.0" (30.5cm) flying leads.
The MDrive23 is a compact, pow-
erful and inexpensive solution that
will reduce system cost, design and
assembly time for a large range of
stepping motor applications.
CONFIGURING
The IMS Motor Interface software
is an easy to install and use GUI
for configuring the MDrive23 from
a computer parallel/SPI port. GUI
access is via the IMS SPI Inter-
face included on the CD shipped
with the product, or download at
www.imshome.com. Optional cables
are available for ease of connecting
and configuring the MDrive.
The IMS Motor Interface features:
•Easy installation.
•Automatic detection of MDrive
version and communication
configuration.
•Will not set out-of-range values.
•Tool-tips display valid range
setting for each option.
•Single screen interface

ORDER INFORMATION
Control Knob
The MDrive23 is available with a factory-mounted rear
control knob for manual shaft positioning.
Planetary Gearbox
Efficient, low maintenance Planetary Gearbox are of-
fered assembled with the MDrive23. Details inside.
Encoder
The MDrive23 is available with a factory-mounted
optical encoder. Available line counts are 100, 200,
250, 400, 500, 1000 or 2000. All encoders, except
1000 line, have an index mark. Encoders are avail-
able in both single-end and differential configurations.
Order optional Encoder Cables separately:
Single-end Cable (12"/30.5cm) ... ES-CABLE-2*
Differential Cable (36"/91.5cm)...ED-CABLE-2*
*Change "2" to a "6" when ordering 2000 line encoder cable.
Linear Actuator
The MDrive23 with long life Acme Screw Linear Ac-
tuator is available with the following travel/full step:
Screw F ...............0.002”/full step
Screw A ...............0.001”/full step
Screw B...............0.0008333”/full step
MDRIVE23 MICROSTEPPING – OPTIONS Screw C ...............0.0005”/full step
Screw D ...............0.0004167”/full step
Screw E................0.0003125”/full step
Standard screw length is 6.0” (152.4mm) plus the
mounting end thread. Custom lengths from 2.0” to
24.0” are available without mounting end thread.
Linear Actuators are Non-Captive style. Contact the
factory regarding Captive Shaft or External styles.
Parameter Setup Cable and Adapter
The optional 6' (1.8m) Parameter Setup Cable Part
No. MD-CC100-000 eliminates the need to wire com-
munications and is recommended with first order. It
connects an MDrive's 10 pin pin-header (P2) to a
standard DB-25 PC Parallel/SPI port and includes
built-in logic level shifting circuity to accommodate the
3.3v ports on some PCs. In addition, MDrives with
C Connector require an Adapter Part No. MD-ADP-
1723C to mate the Cable to the 12 position pin and
receptacle connector (P1).
Prototype Development Cable
For testing and development of MDrives with C Con-
nector, the 12" (30.5cm) Prototype Development
Cable plugs into the MD-ADP-1723C Adapter and
has flying leads for connection to the user interface.
Part No. ADP-3512-FL.
