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.
}
On base modules with Crail:
–
Connect the shield to the terminals on the Crail.
–
Connect the Crail with low impedance to the functional earth.
}
On base modules without Crail:
–
Connect the shield as shown in the terminal configuration section.
–
The module connects the shield to the functional earth via the mounting rail.
}
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.
}
The terminal configuration as stated on the front plate applies for base modules with C
rail. The terminal configuration as stated in the technical documentation applies for all
other base modules.
