Position Lock CAM

281

When you select Synchronize with Next PCam, the block immediately
following the position-lock cam block must be another Position Lock
Cam block or GML Commander does not permit you to connect the two
blocks. In the example above, select Synchronize with Next PCam in the
first two Position Lock Cam blocks—but not in the last block—to start all
three axes simultaneously.

Scaling Position-Lock Cams

You can scale a position-lock cam profile in terms of both master distance
and slave distance when it is executed. Selecting Scale Profile uses the
stored profile for only the shape of the motion, and scales the profile
definition by the total master distance and slave distance over which the
profile is to be executed, as shown below.
