14.2 Measuring functions
A range of measuring functions allows 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.
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-
vant measuring function or operating mode. The measurement or signal param-
eter units are subject to the following conditions:
Table 14-1 Quantity and units for measurement or signal parameters
Size
Unit
Velocity Metric system:
Data in mm/min or rev/min for translation and rotation respectively
Inch system:
Data in inch/min or rev/min for translation and rotation respectively
Distance Metric system:
Data in mm or degrees for translation and rotation respectively
Inch system:
Data in mm or degrees for translation and rotation respectively
Time Specified in ms
Frequency Specified in Hz
Note
The default setting for all parameters is 0.
To ensure that no erroneous traversing movements due to part programs can
be carried out, the measuring functions have to be started in JOG mode.
!
Caution
When traversing movements are carried out within the framework of measuring
functions, no software limit switches and working area limitations are
monitored, since these are carried out in follow–up mode.
Prior to starting traversing motions, the user must therefore ensure that the
axes are positioned such that the traversing limits specified within the
framework of the measuring functions are sufficient to prevent collision with the
machine.
