Safety Specification - Parker AC30P Hardware Installation Manual

Safety Specification

As assessed to EN ISO13849-1 and EN61800-5-2 the inverter has the following related safety values:-
Criterion
SIL3
SIL3
SIL Capability
PLe
PLe
PLe
Mission Time
Fault Reaction Function
Note: all values quoted in this table are valid only when the two STO user inputs are driven independently. This is as required by EN ISO
13849-1 category 3. See the Alignment to European Standards section in this chapter for the required architecture which must be used
throughout the machine design relevant to the drive under consideration.
1
EN ISO13849 limits MTTFd to 100 years.
2
A detected fault in the STO circuit causes STO to become active, and remain active until after a power cycle.
