DESCRIPTION

The MDrive17Plus Microstepping high
torque integrated motor and step and
direction driver is ideal for designers who
want the simplicity of a motor with on­board electronics. The integrated electron­ics of the MDrive17Plus eliminate the need
to run motor cabling through the machine,
reducing the potential for problems due to
electrical noise.

The unsurpassed smoothness and per­formance delivered by the MDrive17Plus
Microstepping are achieved through IMS's
advanced 2nd generation current con­trol. By applying innovative techniques
to control current fl ow through the motor,
resonance is signifi cantly dampened over
the entire speed range and audible noise
is reduced.

The MDrive17Plus accepts a broad input
voltage range from +12 to +48 VDC, deliv­ering enhanced performance and speed.
Oversized input capacitors are used to
minimize power line surges, reducing
problems that can occur with long runs
and multiple drive systems. An extended
operating range of –40° to +85°C provides
long life, trouble free service in demanding
environments.

The MDrive17Plus uses a NEMA 17 frame
size high torque brushless step motor
integrated with a microstepping driver,
and accepts up to 20 resolution settings
from full to 256 microsteps per full step,
including: degrees, metric and arc minutes.
These settings may be changed on-the-fl y
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.

For use in environments where exposure
to chemical, dust and liquids may occur,
a sealed MDrive17Plus-65 Microstepping

unit with 19-pin M23 circular connector
meets IP65 specifi cations.

The versatile MDrive17Plus Microstep­ping is available in multiple con fi g u ra tions
to fi t various system needs. Rotary motor
versions come in three lengths and may in­clude an encoder, control knob, planetary
gearbox or linear slide. Long life Acme
screw linear actuators** are also available.

Numerous connector styles give you
choices for the best fi t and features. Select
from 12.0” (30.5cm) fl ying leads, pluggable
terminal strip, locking wire crimp connec-

, and M23 circular connectors on IP65

sealed versions

MDrivePlus connectivity has never been
easier with options ranging from all-inclu-

sive QuickStart Kits to individual inter­facing cables and mating connector kits

to build your own cables.

The MDrive17Plus is a compact, powerful
and cost effective motion control solution
that will reduce system cost, design and
assembly time for a large range
of brushless step motor applications.

CONFIGURING

The IMS Motor Interface software is an
easy to in stall and use GUI for con fi g ur ing
the MDrive17Plus from a computer's USB
port. GUI access is via the IMS SPI Motor
Interface available at www.imshome.com.

The IMS SPI 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.

• Simple screen interfaces.
