functions?
● How do the safety functions basically work?
● Which sequence is recommended when installing the inverter?
● What options are available to connect the inverter to the higher-level control system
via PROFIsafe?
● How are the PROFIsafe control words and status words assigned?
● How do you wire the fail-safe digital inputs and outputs of the inverter?
● What differences are there when wiring inside and outside the control cabinet?
● How do you connect a monitored motor holding brake?
● Which sequence is recommended when commissioning the inverter?
