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
