Table A- 4 Procedure for the STO acceptance test
Status
1. The inverter is ready for operation

• STO is not active ( r0002 ≠ 44).
(e.g. R0002 = [31] Ready for switching on – set "ON/OFF1" = "1/0" (p0840)
2. Switch on the motor
2.1. Enter a speed setpoint ≠ 0.
2.2. Switch on the motor (ON command).

2.4. Check the status of the safety relay LEDs
(here in the example, a 3SK1112-… or 3SK112x-…)
• LED (1) DEVICE = green
•
LED (2) OUT = green-> 3SK1 output circuit closed
• LED (3) IN = green-> 3SK1 switch-on (close) conditions satisfied
–
Input circuit closed
– Feedback circuit closed
– Start button where necessary actuated
•
LED (4) SF = OFF
