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.

Please note the values stated in the technical details
}
The maximum frequency of the used encoders must be entered for a complete config-
uration ("Encoder" Menu -> "Track AB" -> "Track AB fmax" / "Track Z" -> "Track Z
fmax").

Rotary encoders
}
The following rotary encoders can be used:
–
TTL, HTL (single-ended or differential signals)
–
sin/cos 1 Vss
–
Hiperface
}
The rotary encoders can be connected with or without Z index (0 index)
}
The cable used to connect the rotary encoders must be shielded (see connection dia-
grams in the chapter entitled "EMC-compliant wiring").
}
A proximity switch can also be connected to track Z for monitoring broken shearpins
}
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 example, the encoder's supply voltage can be monitored.
