1.1 Safety characteristic values MOVIFIT® FC/MC with S12 safety optionSafetycharacteristic valuesMOVIFIT®FC/MC withS12 safetyoption

1.1.1 Overall component: S12 safety optionThe tables below show the safety characteristics of the overall component.

Designation Characteristic safety values according toIEC 62061 / IEC

61508EN ISO 13849-1

Classification SIL 21) PL d

System structure HFT = 0 Category 2

Operating mode selection High demand –

Probability of dangerous failure perhour(PFHd value)

< 1.5 x 10-8 1/h < 1.5 x 10-8 1/h

Mission time / service life 20 years

Proof test interval Not required –

Safe state • PROFIsafe: Logic value "0" for all safety-related process values

• Safety-related F-DO outputs: Outputs de-activated (logic "0")2)

Safety functions • STO, SS1, SLS, SDI (according toEN 61800-5-2)

• Safety-related digital inputs and outputs• PROFIsafe communication

1) The S12 safety option is a subsystem of type B according to IEC 61508.2) When a safety-related output is used to control the STO function of the inverter, the function is activated

in a safe state.
