ABB ACS800-104

14 Option description
STO function activation and indication response times
 Module response times only
1)
STO activation response time = delay between de-energizing the STO input and switching off the drive/
inverter output bridge
2)
STO indication response time = delay between de-energizing the STO input and indication of STO input de-
energization
 Response times with typical safety relay
3)
STO activation response time = delay between de-energizing the STO relay and switching off the drive/
inverter output bridge
4)
STO indication response time = delay between de-energizing the STO relay and indication of STO input de-
energization
