} The following tolerance times can be configured for the proximity switches:
– Tolerance time for tracks A and B ("Encoder" menu → "Track AB" → "Track AB Tol.")
– Tolerance time for track S ("Encoder" menu → "Track S" → "Track S Tol.")
The tolerance time influences the sensitivity towards invalid signal levels (e.g. in the
event of EMC interference). The greater the configured tolerance time, the less sensitive
the system will be towards invalid signal levels.
CAUTION!
Delayed reaction to invalid signal levels
Setting a tolerance time increases the reaction time of the feasibility check
of the signal levels. The detection time can increase to a maximum of four
times the set tolerance time as a result. This must be taken into account
when the system is designed.
Proximity switch with reduce diagnostics
With the encoder type 2 proximity switches with reduced diagnostics, the proximity
switches can be arranged at will. This means that the signals from the proximity switches
do not need to overlap. However, this leads to reduced diagnostics.
5.5.2 Rotary encoders
} 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 cable used to connect the encoders must be shielded (see connection diagrams 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.
} The following must be entered for a complete configuration
– The maximum frequency of the used encoders ("Encoder Settings" menu → "Track
AB" → "Track AB fmax" / "Track Z"→ "Track Z fmax").
– When monitoring broken shearpins: The ratio fAB/fZ ("Encoder Settings" menu →
"Track Z" → fAB/fZ Verh.)
} The following tolerance times can be configured for the rotary encoders
– Tolerance time for tracks A and B ("Encoder" menu → "Track AB" → "Track AB Tol.")
– Tolerance time for track Z ("Encoder" menu → "Track Z" → "Track Z Tol.")
– Tolerance time for track S ("Encoder" menu → "Track S" → "Track S Tol.")
