4) Press the “Define Gather Buffer” button

5) Press the “Begin Gathering” button

The Plot feature relies on the PMAC gathering functions. It is very useful for analyzing motion profiles and trajectories.

Using circular interpolation, for example, one axis could be plot Vs the other instead of Vs time. Simulating an X-Y plot

graphically could be a very important aid in understanding the set of parameters involved in a circular interpolation move.

2.3 - Saving and retrieving PMAC parameters

It is very important to periodically save the complete set of PMAC parameters in the host computer. In case of a failure or

replacement, a single file created this way will allow restoring all the variables and programs necessary for the particular

application. To activate this function click on the terminal window, press CTRL+B for the Backup pull-down menu, select

“save configuration” and “global configuration”. Select a meaningful name to be saved as. Usually is a good practice to

include the date as part of the file name for later identification. For example, “ PMAC0112” has four digits for the

application identifier and four digits for the date.

After the file is saved verify it with the feature part of the same pull-down menu. This will make sure PMAC’s memory

matches the recently saved file and therefore that it is a valid restoring file.

To restore a configuration simply select “restore” from the same Backup pull-down menu. It is also suggested to verify

PMAC’s memory after the restore function as well.
