Leading Value Coupling (Leadon, Leadof) - Siemens Sinumerik 840D sl Programming Manual

10.4.23

Leading value coupling (LEADON, LEADOF)

Note
This function is not available for SINUMERIK 828D!
Function
The axial leading value coupling can be programmed in synchronized actions without
restriction. The changing of a curve table for an existing coupling without a previous
resynchronization is optionally possible only in synchronized actions.
Syntax
Activate master value coupling
DO LEADON (following axis, leading axis, curve table no., OVW)
Deactivate leading value coupling
DO LEADOF(following axis, leading axis, leading axis 2)
Significance
Activate axial leading value coupling:
...DO LEADON(FA, LA,
NR, OVW)
Deactivate axial leading value coupling:
...DO LEADOF(FA, LA)
... DO LEADOF(FA)
