    Appendix A.3 Parameter Parameter Parameters are the interface between the firmware of the converter and the commissioning tool, e.g. an Operator Panel. Adjustable parameters Adjustable parameters are the "adjusting screws" with which you adapt the converter to its particular application. If you change the value of an adjustable parameter, then the converter behavior also changes.

A.4.2 Optimize the drive using the trace function Description The trace function is used for inverter diagnostics and helps to optimize the behavior of the drive.
  • Page 274 Appendix A.4 Handling STARTER Trigger You can create your own start condition (trigger) for the trace. With the factory setting (default setting) the trace starts as soon as you press the button (Start Trace). Using the button , you can define another trigger to start the measurement. Using pretrigger, set the time for the recording before the trigger is set.
