The higher-level controller triggers the safety functions in the inverter via the control word.
The inverter uses the status word to report the status of the safety functions to the controller.
The section Selecting the commissioning method (Page 108) contains information to help
you decide whether you must operate your inverter with "Basic Safety" or "Extended Safety".
