A Reference switch
Sequence of case ①:
The axis has not yet acvated the reference switch:
1.
The machine part mo
ves in posive direcon with prole data set 1.
2.
Machine part r
everses 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 nega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:
•
Driv
e stops (default seng).
•
Relave posioning by a set target posion.
•
Ab
solute posioning to a set target posion.
