The following table describes the trigger and indication delay of the STO channels.
STO mode | STO trigger and indication delay1, 2 |
STO fault: STL1 | Trigger delay < 10 ms Indication delay < 280 ms |
STO fault: STL2 | Trigger delay < 10 ms Indication delay < 280 ms |
STO fault: STL3 | Trigger delay < 10 ms Indication delay < 280 ms |
STO fault: STO | Trigger delay < 10 ms Indication delay < 100 ms |
1. STO function trigger delay: Time interval between trigger the STO function and switching off the drive output
2. STO instruction delay: Time interval between trigger the STO function and STO output state indication
