DESCRIPTION
The MDrive NEMA 23 high torque
In te grat ed Motor and Driver is
ide al for designers who want the
sim plic i ty of a motor with on-board
elec tron ics, but without the ex-
pense of an in dex er on each axis.
The low cost MDrive23 allows the
system de sign er to decide the best
meth od of con trol. The MDrive23’s
in te grat ed elec tron ics eliminate
the need to run the mo tor cabling
through the ma chine, reducing the
potential for prob lems due to elec-
tri cal noise.
The MDrive23 uses a NEMA 23
frame size 1.8° high torque step-
ping motor com bined with a mic-
rostepping driver, and ac cepts up
to 14 resolution set tings from ½
to 256 microsteps per full step.
Setup parameters in clude Micro-
step Resolution, Motor Run/Hold
Current, and Motor Di rec tion with
respect to the di rec tion in put.
These set tings may be changed
on-the-fly or down load ed and
stored in nonvol a tile memory with
the use of a sim ple GUI which is
pro vid ed. This elim i nates the need
for ex ter nal switch es or re sis tors.
Pa ram e ters are changed via an
SPI port. Op er at ing volt age for the
MDrive23 ranges from +12 to +48
VDC or +24 to +75 VDC.
The versatile, compact MDrive23 is
available in multiple con fi g u ra tions
to fi t various system needs. These
include a single shaft rotary mo-
tor, a dual shaft rotary mo tor
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. In ter face
The IMS Motor Interface GUI sim pli fi es MDrive
confi guring with a single screen in ter face.
(DIR feature with C Connector version only.)
con nec tions are ac com plished 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) fl ying leads.
The MDrive23 is a compact, pow-
er ful and inexpensive solution that
will reduce system cost, design and
as sem bly time for a large range of
step ping motor applications.
CONFIGURING
The IMS Motor Interface software
is an easy to in stall and use GUI
for con fi g ur ing 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 avail able for ease of con nect ing
and con fi g ur ing the MDrive.
The IMS Motor Interface features:
• Easy installation.
• Automatic detection of MDrive
version and communication
confi guration.
• Will not set out-of-range values.
• Tool-tips display valid range
setting for each option.
• Single screen interface
