Figure A-7 Acceptance test for STO (basic functions)
To perform an acceptance test of the STO function as part of the basic functions, proceed as
follows:
1.
• The inverter signals neither faults nor alarms of the safety functions (r0945[0…7],
r2122[0…7]).
• STO is not active (r9773.1 = 0).
2.
Enter a speed setpoint ≠ 0.
Switch on the motor (ON command).
Check that the correct motor is running.
3.
3.1. Select STO while the motor is running.
Test each configured activation, e.g. via digital inputs and PROFIsafe.
3.2.
When controlled via
PROFIsafe
When controlled via fail-
safe digital inputs (F-DI)
When controlled via
terminals STO_A and
STO_B on Power Mod-
