A-B 4100-234-R IMC™ S Class Compact Motion Controllers

A-B 4100-234-R IMC™ S Class Compact Motion Controllers
The IMC-S/23x is a compact, rugged, microprocessor-based two- orfour-axis servo motion controller. By including the logic and field

power supplies, the IMC-S/23x provides a completely programmable,stand-alone motion and logic controller suitable for a wide variety of
industrial applications.

The IMC-S/23x, in conjunction with external drive systems andfeed-back encoders, provides two or four axes of closed-looppoint-to-point positioning with profile (trapezoidal, parabolic, orS-curve), velocity, acceleration, and deceleration control as well asmulti-axis linear, circular, or helical interpolation. The electronic
gearing feature allows any axis to be slaved to another at a programmable ratio. The electronic cam feature allows coordinated motion
profiles which are functions of time or position of another axis.
Sophisticated phase shift, auto-registration, and auto-correction capa
bilities allow many complex motions and synchronizations to be eas
ily programmed. General-purpose discrete I/O, analog inputs, analog
outputs, etc. are provided by direct connection of Allen-Bradley
Flex™ I/O modules. Up to eight Flex I/O modules—providing a total
of 128 discrete I/O points—may be connected directly to the
IMC-S/23x. Analog inputs and outputs can be substituted for discrete
I/O blocks for increased I/O flexibility

Application programming of the IMC-S/23x for any application is

accomplished with GML, the exclusive Graphical Motion Control
Language from Allen-Bradley. Using GML, over 100 different
commands are available to completely customize operation of the
IMC-S/23x for your specific application. Complete application pro
grams are downloaded to the IMC-S/23x via a field-configurable
RS-232C or RS-422 port where they are stored in non-volatile mem
ory (write-protected battery-backed RAM). Complete hookup diag
nostics and automatic servo setup routines for self-tuning the servo
parameters make setting up the IMC-S/23x quick and easy.
A dedicated serial port—which can be field-configured for RS-232C,
RS-422, or Allen-Bradley DH-485 communications—is provided for
the man-machine interface (MMI). Connection of the MMI device is
via an AT-compatible DB-9 connector (RS-232C or RS-422) or
RJ-45 connector (DH-485), both located on the front panel.
The Remote I/O option allows the IMC-S/23x to communicate with
other Allen-Bradley devices via Remote I/O. The motion controller
can communicate directly with an A-B PLC® using both discrete and
block transfers. The AxisLink option allows axes on other IMC S
Class controllers or ALECs (AxisLink Encoder Converter modules)
to be used as master axes for electronic gearing and cams. This ability
provides real-time coordination for distributed, multi-axis systems in
electronic gearing, cam, lineshaft, and synchronization applications.
Product Features
• Powerful graphical software development system (GML) with
real-time debugging makes application programming easy and
fun.
• State-of-the-art Intel i960 RISC microprocessor.
• Completely digital—no potentiometers or other adjustments
required; will not drift with time, temperature or humidity.
• Multitasking operating system allows simultaneous execution of
up to 10 tasks for efficient utilization.
• Electronic gearing for synchronization of any axis to another at a
programmable ratio. Ratio may be specified as a floating point
number or integer fraction (1⁄3, 3⁄10, etc.).
• Electronic cam for coordinated motion profiles on one or more
axes. Profiles may be position versus time or slave axis position
versus master axis position.
• Sophisticated phase shift and advance/retard capabilities for
electronic gears and cams allow complex motions to be easily
programmed.
• Auto-registration and auto-correction make high-speed
registration applications easy.
• Exclusive Imaginary Axis provides additional command-only
axis for precise generation of master motion in master-slave
applications or correction moves in registration and
synchronization applications.
