direcon with reversing reference switch and negave edge of the reference switch to touch probe
A Touch probe/zero pulse B 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 r
everses with
posive edge of the reference switch (B) and changes to
prole data set 2.
3.
The negave edge of the reference switch (B) acvates the touch probe detecon.
4.
The f
ollowing posive edge of the encoder zero pulse/touch probe sensor (A) sets the ref-
er
ence.
5.
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 (B) acvates the touch probe detecon.
3.
The f
ollowing posive edge of the encoder zero pulse/touch probe sensor (A) sets the ref-
er
ence.
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.
