•
The inverter signals
the following:
"STO selection via
PROFIsafe"
(r9772.20 = 1)
•
The inverter signals
the following:
"STO Selection via
terminal"
(r9772.17 = 1)
•
The inverter signals
the following:
"STO Selection via
terminal on Power
Module"
(r9772.25 = 1)
•
If a mechanical brake is not available, the motor coasts down.

at standstill.
•
The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
•
The inverter signals the following:
"STO is selected" (r9773.0 = 1).
"STO is active" (r9773.1 = 1).
4. Deselect STO
4.1. Deselect STO.
4.2. Check the following:
•
STO is not active (r9773.1 = 0).
•
The inverter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
