Motion Blocks

Also, use the Configure CAM block’s Auto-Correction dialog box to
continuously re-synchronize position-lock cam master and slave axes to
registration marks. See Auto-Correction for details.

The Configure Cam function block resides on the CAM Palette.

Selecting Auto-Correction displays the Auto-Correction page for this
dialog box. See Auto-Correction in this section for instructions on the
Auto-Correction function.

Cam Start and End Points

The motion controllers contain two cam tables that can be used to store
many individual time-lock and/or position-lock cam profiles. The master
cam table stores time values (for time-lock cams) or master axis positions
(for position-lock cams), and the slave cam table stores the corresponding
slave axis positions, as shown below.
