Response to a discrepancy when STO is active

The inverter responds with the active safety function STO to a discrepancy at the fail-safe
digital input.
The inverter response depends on the wiring and the setting of the inverter:
● You are using the basic functions according to SIL 2 → case 1.
● You are using the extended functions → case 2.
● You are using the "STO via Power Module terminals" function → Case 3.
Case 1: Response of the drive for STO of the basic functions
You have selected one of the following settings:
● Basic Functions via onboard terminals
● Basic Functions via PROFIsafe and onboard terminals
● Extended Functions via PROFIsafe and Basic Functions via onboard terminals
