The Y axis is not released early enough in
N60
Corrected example:
Program code
...
N50 WHEN TRUE DO TRAILOF(Y, X)
N55 WAITP(Y)
N60 Y100
Examples
Define coupling: Y = following axis, X = leading axis
Program code
... DO CPLDEF[Y]=X CPLNUM[Y,X]=1.5
Activate coupling and define coupling relationship.
● N10 with the correct sequence: First
● N20 with incorrect sequence: First
Program code
N10 ... DO CPLON[Y]=X CPLNUM[X,Y]=1.5
N20 ... DO CPLNUM[X,Y]=2 CPLON[Y]=X
Activate coupling, deactivation/activation with implicit resynchronization
Program code
N10 ... DO CPLON[X]=Y CPLNUM[X,Y]=3
N20 Y100 F100
N30 ... DO CPLOF=X CPLON[X]=Y CPLNUM[X,Y]=3
Activate coupling, deactivate and traverse as a command axis
Program code
N10 ... DO CPLON[X]=Y CPLNUM[X,Y]=3
N20 Y100 F100
N30 ... DO CPLOF=X MOV[X]=10
