For a full configuration, the maximum frequency of the sensors you are using must be
entered in PAS4000 (see sensor's data sheet).

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 shearpins.
Please note:
Monitoring for broken shearpins does not become active until
– The minimum speed has been exceeded and
– The tolerance for detecting feasibility errors has elapsed.
The minimum speed and tolerance depend on the ratio of the frequency at tracks AB "f
to the frequency at track Z "f
Minimum speed:
– Calculated ratio AB/Z ≥ 1.0
– when f
Tolerance for detecting feasibility errors:
– when fAB/fZ Verh. ≥ 1.0
– when fAB/fZ Verh. < 1.0
}
With Hiperface encoders, only the RefSin and RefCos tracks are recorded and monitored
(see
}
Track S can be used:
– To connect an encoder's error output.
– To monitor voltages between 0 V and 30 V for a permitted upper and lower limit. For

CAUTION!
Appropriate installation measures should be taken to prevent a foreign body
coming between the signal encoder and the proximity switch. If not, the for-
eign body could cause invalid signals.
