The recorded data are automatically stored in file
"C:\Siemens\DriveMonitor\P7vrvisx\Projects\Drives\MASTERDRIVES
MC\ TRACE.TXT" when read out with DriveMonitor. Existing files are
overwritten. The file is an ASCII file with integer values and commas as
separators, which can be imported into commercial mathematical
programs.
Evaluation of the data in a mathematical program is the task of the
user , i.e. the user must first create a worksheet in a mathematical
program in which he or she edits, evaluates, and graphically represents
the data as required.
One suitable program is, for example, the mathematical software"
"Mathcad
®
" produced by the company MathSoft
(http://www.mathsoft.com), which provides a relatively uncomplicated
introduction to the subject area.
The following graphics show the amplitude and phase response of the
closed speed control loop (factory setting, without optimization). The
data was evaluated and displayed graphically using "Mathcad 8
®
".
