Range of user-definable M/H numbers

The maximum number range from 0 to 65535 is provided for the M or H number. The actually available range is limited depending on the version and can be found in the documentation [SYSP]. This is where you will also find details of the limits to the maximum number of M and H functions in each CNC block as well as the maximum number of simultaneously active 'late' synchronization per channel and axis.

The M functions that are reserved in accordance with DIN66025 pose a further restriction (see chapter entitled Default M functions)
