A Reference switch
Sequence of case ①:
The axis has not yet acvated the reference switch:
1.
The machine part mo
ves in negave
direcon with prole data set 1.
2.
The machine part reverses with posive edge of the reference switch (A) and changes to
prole data set 2.
3.
The negave edge of the reference switch (A) sets the reference.
4.
Further
acons can be selected:
•
Drive stops (default seng).
•
Relave posioning by a set target posion.
•
Ab
solute posioning to a set target posion.
Sequence of case ②:
The axis has already acvated the reference switch:
1.
The machine part moves in posive
direcon with prole data set 2.
2.
The negave edge of the reference switch (A) sets the reference.
3.
Further
acons can be selected:
•
Drive stops (default seng).
•
Relave posioning by a set target posion.
•
Ab
solute posioning to a set target posion.

A Touch probe/zero pulse
Sequence of case ①:
1.
The machine part mo
ves to negave
direcon with prole data set 1 and acvates the
touch probe detecon.
2.
The f
ollowing set edge of the encoder zero pulse/touch probe sensor (A) sets the refer-
ence.
3.
Further acons can be selected:

•
Relave posioning by a set target posion.
