General wiring guidelines
Please note:
}
The module's connections are galvanically isolated from the module supply and peri-
phery supply.
}
For EMC reasons we recommend that you operate inputs A, B, C exclusively as differ-
ential inputs with inverted signals (A+/A-, B+/B-, C+/C-).
}
The module evaluates open differential inputs (A+/A-, B+/B-, C+/C-) as a 1 signal.
}
The module evaluates open function inputs (G, L, S) as a 0 signal.
}
Use twisted pair cables to carry the inverted signals. This will increase the noise im-
munity.
}
Use shielded signal cables with metallic plugs. The screening should be connected to
the housing of the D-Sub connector.
}
The channel for the incremental encoder's zero pulse has a different designation de-
pending on the manufacturer (N, C, Z, 0,...)
}
The supply voltages must be extra low voltages with protective electrical separation
(PELV or SELV) in accordance with VDE 0100, Part 410.
}
Use copper wiring.
}
Connect the two sensors via separate cables. This also applies to compact encoders.
