Miscellaneous function M

Functionality
The miscellaneous function M initiates switching operations, such as "Coolant ON/OFF" and
other functionalities.
Various M functions have already been assigned a fixed functionality by the CNC
manufacturer. The functions not yet assigned fixed functions are reserved for free use of the
machine manufacturer.
Note
An overview of the M miscellaneous functions used and reserved in the control system can
be found in section "Overview of instructions".
Programming
M...
Effect
Activation in blocks with axis movements:
If the functions M0, M1, M2 are contained in a block with traversing movements of the axes,
these M functions become effective after the traversing movements.
The functions M3, M4, M5 are output to the internal interface (PLC) before the traversing
movements. The axis movements only begin once the controlled spindle has ramped up for
M3, M4. For M5, however, the spindle standstill is not waited for. The axis movements
already begin before the spindle stops (default setting).
The remaining M functions are output to the PLC with the traversing movements.
If you would like to program an M function directly before or after an axis movement, insert a
separate block with this M function. Please note: This block interrupts the G64 continuous
path mode and generates exact stop.
