DESCRIPTION
The MDrive NEMA 34 high torque
Integrated Motor and Driver is ideal
for designers who want the simplicity
of a motor with on-board electronics,
but without the expense of an in-
dexer on each axis. The low cost
MDrive34 puts the system designer
in the driver’s seat to decide the best
method of control. The MDrive34’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 MDrive34 uses a NEMA 34
frame size 1.8° high torque mo-
tor combined with a microstep-
ping driver, and accepts up to 14
resolution settings from ½ to 256
microsteps per full step. Setup pa-
rameters include Microstep Resolu-
tion, 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. MDrive34 operating voltage
ranges from +24 to +75 VDC.
The MDrive34 is available in multiple
configurations to fit various system
needs including a single shaft rotary
motor with optional internal optical
encoder, a dual shaft rotary motor
with control knob, a planetary gear-
box, or a long life Acme screw linear
actuator. The rotary MDrive34 is
available in single, double and triple
stack sizes: 24, 31 & 47. Interface

The IMS Motor Interface GUI simplifies MDrive
configuring with a single screen interface.
connections are accomplished using
12.0" (30.5cm) flying leads.
The MDrive34 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 MDrive34 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. An optional
cable is available for ease of con-
necting 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
