The higher-level control selects the safety functions in
the inverter via the control word S_STW1. The inverter
uses the status word S_ZSW1 to report the status of
the safety functions to the controller.
Telegram 900 of the PROFIsafe profile also contains
control and status word 5. The inverter uses status
word S_ZSW5 to transfer the state of the safety digital
inputs to the control.
