The higher-level control selects the safety func‐
tions in the inverter via the control word S_STW1.
The inverter uses the status word S_ZSW1 to re‐
port the status of the safety functions to the con‐
troller.
Telegram 900 of the PROFIsafe profile also in‐
cludes control and status word 5. The inverter
transfers the status of the fail-safe digital inputs
F‑DI 0 ... F‑DI 2 to the control system in status
word S_ZSW5.
