Note!
For a reference search with touch probe detection:
• Select the touch probe signal source in C01246/1. Select the edge to which
the digital input used for the connection of the touch probe sensor is to
respond in C02810/x. In the Lenze setting of
detected!
• Moreover, no "acceptance window" must be set in
accepting the touch probe signal in order that a touch probe will always be
detected independent of the position.
Touch probe detection
Start and search profile data set
Certain referencing modes use two different profile data sets for homing in order to
shorten the homing time and, at the same time, increase accuracy.
 At first, a quick approach of the limit switch/pre-stop mark (depending on the selected
mode) is carried out using the start profile data set.
 After reversing at the limit switch/pre-stop mark, the search profile data set results in
slower – but more accurate – approaching of the touch probe sensor.


Note!
A changeover to the search profile data set is only carried out of the search speed
has been set to (C01224/2) > "0"!
The exact time of the changeover to search profile data set occurs in the
respective referencing mode is indicated in the process descriptions of the
referencing modes.

Tip!
The result of setting a lower search speed in
acceleration in
and position detection is exact (at slower search speed).
