Response to a discrepancy when STO is active

The inverter responds to a discrepancy at the safety input by activating safety function STO.
The inverter response depends on the setting of the inverter:
● You are using the basic functions → case 1.
● You are using the extended functions → case 2.
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

Inverter messages after the tolerance time has expired:
● Discrepancy (fault F01611 or F30611 with fault values r0949 = 2000 or 2002)
● The inverter sets the error bit of the safety functions (= internal event).
