Status
3. Select STO
3.1. Select STO while the motor is running.
Test each congured activation, e.g. via digital inputs and PROFIsafe.
3.2.
Check the following:
When controlled via PROFIsafe When controlled via fail-safe digital
inputs (F-DI)
• The converter signals the following:
"STO selection via PROFIsafe"
(r9772.20=1)
• The converter signals the follow‐
ing:
"STO Selection via terminal"
(r9772.17=1)
• If a mechanical brake is not available, the motor coasts down.
A mechanical brake brakes the motor and holds it to ensure that it remains at
standstill.
• The converter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
• The converter 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 converter signals neither faults nor alarms of the safety functions
(r0945[0…7], r2122[0…7]).
You have performed the acceptance test of the STO function.
