M functions before
and after tool
measurement
Markers in the PLC
1560
Machine parameters MP6562.0 and MP6562.1 can be used to run M
functions before and after a tool measurement cycle (TT cycle). MP6562.0
activates an M function before the beginning of a cycle, MP6562.1 after
the end of a cycle. You need to program M-function macros in an NC
block to be able to run them.
If the M-function macros are used to make changes that are not automatically
undone at an internal stop, you must ensure that the machines are restored to
a consistent state (e.g. through a suitable cancel macro).

M function before and after tool measurement
Input:

-1: Function inactive
M4060 is set if a cycle for tool measurement is started.
M4061 displays whether a cycle was activated for tool measurement or for
tool checking.
M4062 and M4063 are set if during tool checking one of the entered
tolerances was exceeded. The tool is locked.
The markers M4050, M4051, M4052, M4053, M4055 and M4056 function as
in the standard cycles. You must enable the cycles for tool measurement with
M4055. For spindle orientation directly by the NC (MP6560 = –1), you must
reset M4012.
