A-B IMC™ S Class Compact Motion Controllers Model Number Explanation

Model Number Explanation

The IMC-S/23x is available as a two- or four-axis motion controller

with optional Remote I/O and AxisLink. The complete model number

is specified as shown below.

Pre-engineered cable assemblies are used for connecting the Flex I/O,

servo amplifiers, feedback devices, axis-specific (dedicated) I/O,

CPU watchdog, and the 4100-REC. The table below shows the avail

able cable assemblies.

High Level Motion Functions

As shown in the figure below, the IMC-S/23x can produce motion on

any axis in many different ways. The indexer moves an axis using

either a trapezoidal, parabolic, or S-curve (controlled jerk) velocity

profile. Axis velocity, acceleration, and deceleration are programma

ble. Backlash compensation allows precise positioning in the pres

ence of mechanical backlash. The jogger produces constant speed

motion of an axis in either direction with programmable velocity,

acceleration and deceleration.

Electronic gearing allows any axis to be slaved to another axis (the

master) at a specified ratio. Electronic cams produce coordinated

motion profiles which are functions of time or the position of another

axis. Electronic gearing and cam motion may be combined with move

and jog motions to create complex motion profiles and synchroniza

tions. Motion merge capabilities allow smooth transitions between all

types of motion, thus providing a software clutch.

Two independent interpolators for all axes allow any two or three

axes to be moved as a group along a linear, circular or helical path.

Motions from the two interpolators may be combined with each other

or with other types of motion.
