8.8.11 "Function generator" tab
You can use the "Function generator" tab, to dynamically generate setpoint values
of a defined shape (e.g. rectangular, sine) for a variety of system variables for test
purposes. By using the trace, you can then record the system response in order,
for example, to tune the controllers.
Two function generators are provided which you can start either separately or in
synchronism. The Trace of a SINAMIC drive provides only one function generator.
In the drop-down list of the "Function generator" toolbar select the function
generator. The toolbar buttons are used to enable and disable the function
generator, and to couple, start and stop it. Carry out the menu command Trace >
Toolbars > Function generator in order to display the toolbar.
In the "Function generator" tab, select the system variable to be assigned the
signal of the function generator, the signal type and its parameter (e.g. amplitude,
period, rampup time).
Use the "Function generator" and "Trace" toolbar buttons to control the Download
of your configuration to the PLC.
