Note!
Profile data set change-over
For the reference search, two profile data sets with different speeds and accelerations
can be parameterised. In this way, the homing time can be reduced and at the same time
the accuracy can be increased.
The following process descriptions give information about the time the change-over to
the profile data set 2 takes place in the corresponding homing mode.
If the speed 2 (
) is set to "0" (Lenze setting), 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.
