8.6.1.3 Home position & home value offset
If the home position is set in the course of the reference search, this determined position in the
machine measuring system now corresponds to the home position set in C01227/2 .
If a home value offset has been set in C01227/1 , the drive continues correctly signed traversing by
this offset at search speed after the home position has been found. The home position is not set
until after this movement.
8.6.1.4 Traversing a sequence profile after completion of homing
If necessary, a sequence (following or subsequent) profile can be entered in C01228 in order to
arrange for a positioning movement to be carried out immediately after completion of homing.
8.6.1.5 Measurement of the distance between pre-stop mark/limit switch and TP/MP
The measurement is executed for the homing modes 4, 5, 6, 7, 10 and 11.

Note!
The positioning movement for the sequence profile set in C01228 is also carried out in
the "referencing" mode. If a second sequence (following or subsequent) profile has been
defined in the sequence profile, it is not automatically started!
 Jitter of the pre-switch off signal
Depending on how close the pre-stop mark is located to the
encoder zero pulse and even jittering around it, it might occur
that the drive performs one more or one less revolution after
the home position detection has been enabled.
From version 14.00.00 , the display parameter C01210/9 is
available for this purpose. This parameter shows the distance
between the signal which starts the home position detection
and the detected touch probe signal or encoder zero pulse (MP)
in [units].
