mbalentine Posted November 23, 2011 Share Posted November 23, 2011 By default the "Gather Period" is set to 10 This means that every ten servo interrupts, the data is captured. If you want to gather more often, you can do two things: 1) Reduce the Gather period setting in the PMAC Plot software 2) Decrease the servo interrupt time (requires substantial review of I-vars and retune) Gathering more often will result in more data, so you may want to define a larger buffer with the "Define Gather" command. All data is captured & stored in real time on the PMAC, and is then downloaded after for graphing / analysis. This allows very high speed & accurate data, but you must be sure to provide a large enough memory buffer. If you are gathering multiple data points, you might consider breaking them up into smaller grougs - for instance gather data for only one motor at a time.
