} A proximity switch can also be connected to track Z to monitor for broken shearpins.
Please note:
Broken shearpin monitoring only becomes active when
– The minimum speed is exceeded
and
– The tolerance for detecting feasibility errors has elapsed.
The minimum speed and tolerance depend on the ratio of the frequency on tracks AB
"f

" to the frequency on track Z "f
Z
" in your configuration (see PNOZmulti Configurator
Motion Monitor Element, Calculated Ratio AB/Z).

} With Hiperface encoders, the Sin- Cos track is recorded and monitored via an adapter
(see Adapters for encoders [
749]).
} 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 maximum frequency of the used encoders must be entered for a complete config-
uration.
} Pay attention to the values in the technical details.
