8.6.1.1 Referencing mode
Specify the referencing mode in C01221 , i.e. the way in which referencing is to take place.
• For reference setting, the referencing mode "100" is to be selected in C01221 .
• For a reference search, C01221 contains referencing modes "6"..."15" which can be selected
from.
Internal interfaces
The switches/sensors are evaluated via the following internal interfaces:

Switch/sensor Internal interface for digital input signal
Touch probe sensor
(Sensor reference signal)
• Up to and including version Version 02.xx.xx , a signal at digital
input DI3 is automatically interpreted as TP sensor signal with
level sensitivity.
• That way, TP sensitive homing modes can be used even if high
TP precision is not available.
• In this case, the search speed must be selected in order that the
signal at DI3 will be detected.
• From version 06.00.00 , high-precision homing with touch probe
is supported.
• The touch probe signal source can be selected in C01246/1 .
• If the reference signal is to follow a real touch probe, configure
the touch probe signal accordingly.  Touch probe detection

Pre-stop mark/pre-stop signal bHomingMark
• This input responds to the FALSE status and is to be connected to
the corresponding digital input to which the reference switch is
connected.
• The response to the pre-switch off signal depends on the
referencing mode selected.
