Measuring functions

Explanation
A range of measuring functions allow the time and/or frequency response of
drives and closed-loop controls to be displayed in graphic form on the screen.
For this purpose, test signals with an adjustable interval are connected to the
drives.
Measurement/
The test setpoints are adapted to the application in question by means of mea-
surement or signal parameters, the units of which are determined by the rele-
signal parameters
vant measuring function or operating mode. The measurement or signal param-
eter units are subject to the following conditions:

information
Functions which initiate a traversing motion are selected via the softkey menu;
they are all actually started by means of the NC START key on the machine
control panel. If the basic display for the function is deselected without the tra-
versing motion being initiated, then the function selection is reset.
Once the traversing function has been started, the basic display can be dese-
lected without any affect on the traversing motion.
