Read this section for a brief introduction to ClearPath technology and
terminology through an example application. Please visit

PERATION
Note: This section describes only one example application in one mode of
operation
. Absolute Positioning (4-position) mode allows you to define up
to four target positions and command moves between any of them simply
by changing the logical states of the ClearPath inputs.
In the figure below, a ClearPath model MCPV is coupled to a ball screw
positioning stage. For now, we’ll say that ClearPath has already been
configured and programmed via the included MSP software. This just
means that the mode of operation, target positions, velocity, acceleration,
and options are already stored in ClearPath memory and the motor is
tuned and ready to go. ClearPath configuration and setup will be
discussed later in this section.

Getting started.
To energize the motor, simply apply a DC voltage to the
Enable input. Once enabled, the motor is considered “live”, i.e. the motor
is energized and will execute moves in response to state changes at Inputs
A and B.
Caution:
Depending on the exact mode and settings selected, ClearPath
may automatically move upon enable
with no user changes to the inputs
.
