Safety sub-functions
The TONiC Functional Safety (FS) encoder system provides safe position data that supports the following safety sub-functions defined by IEC 61800-5-2:
•
Safe stop 1 (SS1) and Safe stop 2 (SS2)
•
Safe operating stop (SOS)
•
Safe limited acceleration (SLA) ≤ 500 m/s
•
Safe acceleration range (SAR) ≤ 500 m/s
•
Safe limited speed (SLS) ≤ 10 m/s
•
Safe speed range (SSR) ≤ 10 m/s
•
Safely limited position (SLP)
•
Safely limited increment (SLI)
•
Safe direction (SDI)
•
Safe speed monitor (SSM) ≤ 10 m/s
The system must be installed and operated in accordance with the instructions defined by the installation guide. Failure to follow the correct use instructions and failure to heed the limitations may result in
PLd and / or SIL2 not being achieved and will invalidate the functional safety certification.
