**Consult Factory for Availability.
Optional communication protocols
include CANopen. The CAN bus is 2.0B
active (11 and/or 29 bit) and is capable
of all standard frequencies from 10 kHz
to 1 MHz. CANopen features include
node guarding, heartbeat producer,
SDOs and PDOs. Highlights include
variable PDO mapping and extended
node identifier.
The MDrive34AC Plus2Motion Control
is available with optional closed loop
control. This increases functionality by
adding stall detection, position mainte-
nance and find index mark.
The closed loop configuration is added
via a 512 line (2048 edge) optical
encoder with index mark, internal to the
MDrive34AC so there is no increase in
length. Or, for an expanded choice of
line counts and resolutions, closed loop
control is available with an interface
to a remotely mounted user-supplied
external encoder.
In addition to encoder options, the
MDrive34AC Plus2Motion Control has
the capability of electronic gearing by
following a rotary or linear axis at an
electronically controlled ratio, or an
output clock can be generated fixed to
the internal step clock.
A sealed version designed to meet
IP65 specifications is also available.
The sealed assembly allows the
MDrive34AC to be used in environ-
ments where exposure to chemical,
dust and liquids may occur.
Three rotary motor lengths are avail-
able as are linear actuators with long
life Acme screw**.
Interface connections are accomplished
using standard industrial circular con-
nectors. And connectivity has never
been easier with options ranging from
all-inclusive QuickStart Kits to indi-
vidual interfacing cables. See pg 4.

DESCRIPTION
The MDrive34AC Plus2 Motion Control
system offers designers a cost effec-
tive, full featured programmable motion
controller integrated with a NEMA 34 high
torque 1.8° brushless step motor and a
microstepping driver operating at 120 or
240 VAC.
Unsurpassed smoothness and perfor-
mance delivered by the MDrive34AC are
achieved through IMS's advanced 2nd
generation current control. By applying
innovative techniques to control current
flow through the motor, resonance is sig-
nificantly dampened over the entire speed
range and audible noise is reduced.
The MDrive34AC accepts a broad input
voltage range from 95 to 264 VAC, deliv-
ering enhanced performance and speed.
Oversized input capacitors are used to
minimize power line surges, reducing
problems that can occur with long cable
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 MDrive34AC Plus2Motion Control
system adds a versatile array of functions
by combining a full featured program-
mable motion controller with our compact
and cost effective MDrive34AC Micro-
stepping products, adding little cost and
no increase in size. Standard offerings
include up to 8 general purpose I/O lines
(sourcing or sinking) that operate to +24
VDC, one 10 bit analog input, electronic
gearing, high speed position capture
input/trip output, microstep resolutions up
to 51,200 steps per revolution, 0 to 5 MHz
step clock rate, and a full featured easy-
to-program instruction set.
The MDrive34AC Plus2Motion Control
system communicates over RS-422/485
which allows for point-to-point or multiple
unit configurations utilizing one commu-
nication port. Addressing and hardware
support multiple uniquely addressed units
communicating over a single line.
