11.6.2.5 Profile data set change-over
For the reference search two profile data sets 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/reference switch, the slower – but more accurate – approach
of the encoder zero pulse/touch probe sensor and the positioning to the target position
( C02643 ) are effected with profile data set 2.

Note!
The change-over to profile data set 2 is only effected if speed 2 ( C02646 ) is set > "0"!
In the Lenze setting ( C02646 = "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 process descriptions of the homing modes provide information about when the
change-over to profile data set 2 takes place in the respective homing mode.  Overview
