8.7 Programming an auxiliary function

Output duration
The following priorities apply to the output duration:
Priority Output behavior
Highest Auxiliary function-specific
↓ Auxiliary function-specific
↓ Group-specific
Lowest Not defined
Output relative to motion
The following rules apply to output relative to motion:
Priority Output behavior
Highest Auxiliary function-specific
↓ Group-specific
↓ Type-specific
Lowest Not defined
Note
Part program blocks without path motion
In a part program block without a path motion (even those with positioning axes and spindles),
the auxiliary functions are all output immediately in a block.
8.7 Programming an auxiliary function
Syntax
An auxiliary function is programmed in a part program block with the following syntax:
<Type>[<Address extension>=]<Value>
412
Defined via:
Part program instruction: QU(...)
(see Section "Programmable output duration (Page 414)")
