3.9.7 Profile data set change-over
For the reference search two profile data sets with different speeds and accelerations can
be parameterised to reduce the homing time and increase the accuracy:
 With the profile data set 1 first the limit switch/reference switch (depending on the
mode selected) is quickly approached.
 After reversing on the limit switch/tripping of the reference switch the profile data set
2 causes the touch probe sensor to be approached slower but more precisely and the
subsequent positioning to the target position (C02643).

Note!
The change-over to the profile data set 2 is only carried out if the speed 2
( 0x6099/2 ) is set to > "0"!
In the Lenze setting ( 0x6099/2 = "0") no change-over to the profile data set 2
takes place and the reference search and positioning to the target position is
only executed with the profile parameters of the profile data set 1.
The following process descriptions of the homing modes give information about
the time the change over to profile data set 2 takes place in the corresponding
homing mode.
