13.3.7 Safety-related characteristic data for operation with a safe rotary
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 (PNOZ
s30) must normally detect designated errors. Details of the safe encoder's requirements of
the evaluation device can be found in the user documentation for the safe encoder. The en-
coder and evaluation device must be compatible.
13.3.7.1 Permitted encoder types and output signals
Permitted encoder types:
} Rotary safe encoder
} Linear safe encoder
Permitted output signals:
} Square output signals TTL, differential with Z index
} Square output signals HTL, differential with Z index
} Sin/Cos output signals 1Vss, reference voltage with Z index
} Sin/Cos output signals 1Vss, differential with Z index
