Measuring functions
Explanation
There are a range of measuring functions for displaying the time and frequency
behavior of drives and controls in graph form on screen. Test signals of variable
duration are applied to the drives for this purpose.
Measuring/signal
The test setpoints are adapted to the application by means of measuring and
signal parameters. The units of these parameters depend on the measuring
parameters
function or operating mode. The following conditions apply for the units of these
measuring and signal parameters:

Torque
Velocity/speed
Distance
Time
Frequency
Note
All the parameters are preceded with 0.
Requirements for
The measuring functions must be started in "JOG" mode to ensure that there
starting measuring
are no accidental traversing motions due to part programs.
