Output after motion
• The traverse movements (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 traverse movements.
• 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
2.1.5 Examples of output behavior
Inputs
The following figures illustrate the differing behavior regarding:
• Output and acknowledgment of the auxiliary function
• Spindle response (speed change)
• Traverse movement (velocity change)
Parameterized output behavior
The binary values specified in the examples under "Spec" refer to the parameterized output
behavior:
