Further information
Number of function outputs per NC block
Up to 10 function outputs can be programmed in one NC block. Auxiliary functions can also be
output from the action component of synchronized actions.
Grouping
The functions described can be grouped together. Group assignment is predefined for some
M commands. The acknowledgment behavior can be defined by the grouping.
High-speed function outputs (QU)
Functions, which have not been programmed as high-speed outputs, can be defined as high-
speed outputs for individual outputs with the keyword QU. Program execution continues without
waiting for the acknowledgment of the miscellaneous function (the program waits for the
transport acknowledgment). This helps avoid unnecessary hold points and interruptions to
traversing movements.
Note
The appropriate machine data must be set for the "High-speed function outputs" function
(→ machine manufacturer).
