12.2.4 Error detection of STO safety function
If SF1 or SF2 signal is input first and the other signal is not input within 10 seconds, alarm AL.Eb1 (Safety
function signal input timing error) will occur. Use alarm AL.Eb1 to identify if STO signals are correctly
input.
Alarm AL.Eb1 (Safety function signal input timing error) can be used to check if STO signals are correctly input. But
STO safety function can still normally operate.
12.2.5 Transition time of STO safety function
When STO safety function is enabled by setting SF1 and SF2 signals to OFF, the power supplied to the
motor will be cut off in 7 ms. The servo drive changes from S-RDY state to STO state.
