Encoder
}
The following encoders can be used:
–
TTL, HTL (single-ended or differential signals)
–
Sin/Cos 1 Vss
–
Hiperface®
}
The encoders can be connected with or without Z index (0 index).
}
The cables used to connect the encoders must be shielded (see connection diagrams
in the chapter entitled "EMC-compliant wiring").
}
A pnp proximity switch can also be connected to track Z for monitoring broken shear-
pins.
Please note:
Monitoring for broken shearpins does not become active until
