1.1.6 Homing methods to switch with index search
The following can be used for homing to a proximity sensor:
1. The integrated reference switch of the drive (recomĆ
mended). It is located on the retracted (negative) end
position and must not be moved (exception: minimum
offset with an Index pulse warning", see section 6.6).
2. A proximity sensor to be externally attached by the user.
The proximity sensors can be configured as reference
switches or as limit switches. This means homing either runs
to the reference switch or to the limit switch.
If a proximity switch is configured both as a reference switch
and as a limit switch, then its signal during homing is
interpreted as a reference signal, and afterwards as a limit
switch signal in the referenced state of the drive.
