10.5 Measuring functions (manual tuning)
Explanation of the measuring functions
A range of measuring functions allows the time and frequency response of drives and controls
to be displayed in graphical form on the screen. For this purpose, test signals with an adjustable
interval are connected to the drives.
The measuring functions are located under "Commissioning" → "Optimization/Test". The
current controller, speed controller, and position controller horizontal softkeys provide access
to the dialogs for each corresponding control loop. The screen navigation, screen layout, and
general logic are identical in each of the three areas. The difference between the areas is that
each area on the relevant control loop offers tailored measurements.
Measurement parameters and 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 default setting for all parameters is 0.
The measurement or signal parameter units are subject to the following conditions:
Size
Velocity
Distance
Time
Frequency
