H2: Auxiliary function outputs to PLC
8.2 Predefined auxiliary functions
Basic Functions
418 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Output after motion
• The traversing motions (path and/or block-related positioning axis movements) of the current part program
block end with an exact stop.
• The auxiliary functions are output after completion of the traversing motions.
• The block change is performed after acknowledgment of the auxiliary functions by the PLC:
- Output duration one OB1 cycle (normal acknowledgment): after one OB1 cycle
- Output duration one OB40 cycle (quick acknowledgment): after one OB40 cycle
Examples of different output behavior
The following figures illustrate the differing behavior regarding:
• Output and acknowledgment of the auxiliary function
• Spindle response (speed change)
• Traverse movement (velocity change)
The binary values specified in the diagrams under "Output behavior" refer to the parameterized output behavior
(MD22080).
