8.6
Priorities of the output behavior for which parameters have been
assigned
The following priorities must be observed for the following areas in connection with the parameterized output
behavior of an auxiliary function:
• Output duration (normal / quick acknowledgment)
• Output relative to motion (prior to / during / after the motion)
As a general rule, the parameterized output behavior with lower priority becomes active if no output behavior with
higher priority has been parameterized.
Output duration
The following priorities apply to the output duration:
Output relative to motion
The following rules apply to output relative to motion:

Default output behavior: Output at block end
Note
Parts 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.
