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
Adapters for encoders [
28]
).
}
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.
