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 identi
fi
er.
The MDrive42AC Plus
2
Motion Control
is available with optional closed loop
control. This increases functionality by
adding stall detection, position mainte-
nance and
fi
nd index mark.
The closed loop con
fi
guration is added
via a 512 line (2048 edge) optical
encoder with index mark, internal to the
MDrive42AC 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
MDrive42AC Plus
2
Motion 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
fi
xed to
the internal step clock.
A sealed version designed to meet
IP65 speci
fi
cations is also available.
The sealed assembly allows the
MDrive42AC to be used in environ-
ments where exposure to chemical,
dust and liquids may occur.
Two rotary motor lengths are available
as are linear actuators with long life
Acme screw**.
In ter face con nec tions are ac com plished
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
.

FEATURES
DESCRIPTION
The
MDrive42AC Plus2 Motion Control
system of fers de sign ers a cost effec-
tive, full featured programmable motion
con trol ler in te grat ed with a NEMA 42 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 MDrive42AC are
achieved through IMS's advanced 2nd
generation current control. By applying
innovative techniques to control current
fl
ow through the motor, resonance is sig-
ni
fi
cantly dampened over the entire speed
range and audible noise is reduced.
The MDrive42AC 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 MDrive42AC Plus
2
Motion Control
system adds a versatile array of func tions
by com bin ing a full featured pro gram -
ma ble mo tion controller with our com pact
and cost ef fec tive MDrive42AC Micro-
stepping products, adding little cost and
no increase in size. Stan dard of fer ings
include up to 8 general pur pose I/O lines
(sourcing or sinking) that operate to +24
VDC, one 10 bit analog in put, electronic
gearing, high speed position capture
input/trip output, microstep res o lu tions up
to 51,200 steps per rev o lu tion, 0 to 5 MHz
step clock rate, and a full fea tured easy-
to-program in struc tion set.
The MDrive42AC Plus
2
Motion Control
system com mu ni cates over RS-422/485
which al lows for point-to-point or multiple
unit con
fi
g u ra tions utilizing one com mu -
ni ca tion port. Addressing and hard ware
support multiple uniquely addressed units
com mu ni cat ing over a single line.
