A-B IMC™ S Class Compact Motion Controllers (IMC-S/23x Models)

Product Description

The IMC-S/23x is a compact, rugged, microprocessor-based two- or

four-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 and

feed-back encoders, provides two or four axes of closed-loop

point-to-point positioning with profile (trapezoidal, parabolic, or

S-curve), velocity, acceleration, and deceleration control as well as

multi-axis linear, circular, or helical interpolation. The electronic

gearing feature allows any axis to be slaved to another at a program

mable 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.
