ABB ACS580-04 Kurzanleitung Für Die Installation Und Inbetriebnahme Seite 19

Double-shielded twisted-pair cable is recommended for the connection. The maximum
length of the cabling between the switch and the drive control unit is 300 m (1000 ft).
Ground the shield of the cable at the control unit only.
Validation
To ensure the safe operation of a safety function, a validation test is required. The
test must be carried out by a competent person with adequate expertise and
knowledge of the safety function. The test procedures and report must be documented
and signed by this person. Validation instructions of the STO function can be found
in the drive hardware manual.
Technical data
• The voltage at the STO input terminals of the drive must be at least 13 V DC to be
interpreted as "1"
• STO reaction time (shortest detectable break): 1 ms
• STO response time: 2 ms (typical), 30 ms (maximum)
• Fault detection time: Channels in different states for longer than 200 ms
• Fault reaction time: Fault detection time + 10 ms.
• STO fault indication (parameter 31.22) delay: < 500 ms
• STO warning indication (parameter 31.22) delay: < 1000 ms.
• Safety integrity level (SIL, EN 62061): 3
• Performance level (PL, EN ISO 13849-1): e
The STO is a type B safety component as defined in IEC 61508-2.
For the full safety data, exact failure rates and failure modes of the STO function, refer
to the drive hardware manual.
