K5: Mode groups, channels, axis interchange
6.5 Marginal conditions
Change from a channel axis
The change of a channel axis to a neutral axis or PLC axes cannot be performed during an
active path operation.
With RELEASE this is caused by the fact that RELEASE must be located in a separate NC
block.
If the PLC changes the axis type, a REORG is triggered internally. Therefore, the change
with the listed program conditions is delayed.
Block search
During block search with calculation, all GET, GETD or RELEASE blocks are stored and
output after the next NC Start.
