9.1.7 Safety-related characteristic data for operation with a safe encoder
with Z index
Safe encoders are certified in accordance with EN 61508, EN 13849 and EN 62061. In or-
der to achieve the safety level stated by the encoder, the safe evaluation device (PSSu K F
EI CV(-T)) must normally detect designated errors. Details of the safe encoder's require-
ments of the evaluation device can be found in the user documentation for the safe en-
coder. The encoder and evaluation device must be compatible.
9.1.7.1 Permitted sensor types and output signals
Permitted encoder types:
}

}
Sin/Cos output signals 1Vss, differential with Z index
9.1.7.2 Safety-related architecture
To calculate the safety function you will need the following data for the "sensor" subsystem
and the subsystem "PSSu K F EI CV(-T)":
