Inadmissible number of late sync function in axes.
Description | The number of axis-specific M functions programmed in an NC line with late synchronisation (Late sync, types MVS_SLM, MVS_SLP) is limited. After triggering the active M functions with G01 motion block or explicit triggering via NC command, the M functions are enabled internally until synchronisation with the PLC.

For more detailed information about M/H functions, see

[FCT-C1// Section: Reaction of “late” synchronisation].

[FCT-C1// Section: Parameterising the synchronisation methods].

Response | Class | 4 | Movement stop.
Solution | Class | 6 | Reduce the of axis-specific M functions programmed per NC line with late synchronisation.
Parameter | %1: | Logical axis number [-]
Logical axis number of axis affected P-AXIS-00016.
%2: | Block number [-]
Block number in the NC program.
%3: | Current value [-]
Number of M functions currently programmed in the axis and NC line with late synchronisation.
%4: | Limit value [-]
Maximum number of permissible M functions with late synchronisation per axis and NC line.
Error type | -
