Patent Pending
a sealed MDrive42AC Plus Microstepping
unit with circular connectors meets IP65
speci
fi
cations.**
The versatile MDrive42AC Plus Micro-
stepping is available in multiple con
fi
g u-
ra tions to
fi
t various system needs. Two
rotary motor lengths are available and
may include an internal optical encoder, a
control knob for manual positioning or an
integrated planetary gearbox.
In ter face con nec tions are ac com plished
using standard industrial circular connec-
tors. And connectivity has never been
easier with options ranging from
all-in-
clusive QuickStart Kits
to
individual
interfacing cables
.
See pg 5.
The MDrive42AC Plus is a compact, pow-
erful and cost effective 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 MDrive42AC Plus 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 con
fi
guration.
• Will not set out-of-range values.
• Tool-tips display valid range
setting for each option.
• Simple screen interfaces.
DESCRIPTION
The
MDrive42AC Plus Microstepping
high torque integrated motor and step and
direction driver is ideal for designers who
want the simplicity of a motor with on-
board electronics. The integrated electron-
ics of the MDrive42AC Plus eliminate the
need to run motor cabling through the ma-
chine, reducing the potential for problems
due to electrical noise.
The unsurpassed smoothness and per-
formance delivered by the MDrive42AC
Plus 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 signi
fi
cantly dampened over
the entire speed range and audible noise
is reduced.
The MDrive42AC Plus accepts a broad
input voltage range from 95 to 264 VAC,
delivering enhanced performance and
speed. Oversized input capacitors are
used to minimize power line surges, re-
ducing problems that can occur with long
runs and multiple drive systems. An ex-
tended operating range of –40° to +75°C
provides long life, trouble free service in
demanding environments.
The MDrive42AC Plus uses a NEMA 42
frame size high torque brushless step mo-
tor combined with a microstepping driver,
and accepts up to 20 resolution settings
from full to 256 microsteps per full step, in-
cluding: 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,
