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

NOTICE
If interference can be anticipated on the signal cables or if the sensor cables
are long, we recommend you use encoders with differential signals. De-
pending on the sensor, terminating resistors should be used to improve the
quality of the signal (see sensor's data sheet).
}
With Hiperface encoders, the Sin- Cos track is recorded and monitored via an adapter
(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
example, the encoder's supply voltage can be monitored.
}
The maximum frequency of the used encoders must be entered for a complete configura-
tion.

Pay attention to the values in the technical details.
