Measuring functions
Explanation
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.
Measurement/signal parameters
The test setpoints are adapted to the application in question by means of measurement or
signal parameters, the units of which are determined by the relevant measuring function or
operating mode. The measurement or signal parameter units are subject to the following
conditions:
Table 14-1 Quantity and units for measurement or signal parameters
Size
Unit
Velocity
Metric system:
Specification in mm/min or rev/min for translatory or rotary movements
Inch system:
Specification in inch/min or rev/min for translatory or rotary movements
Distance
Metric system:
Specification in mm or degrees for translatory or rotary movements
Inch system:
Specification in inch or degrees for translatory or rotary movements
Time
Specified in ms
Frequency
Specified in Hz
Note
The default setting for all parameters is 0.
Preconditions for starting measuring functions
To ensure that no erroneous traversing movements due to part programs can be carried out,
the measuring functions have to be started in the 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 movements, 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.
