# ID 50388

Inadmissible number of late sync functions in the channel.
Description | The number of channel-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 number of channel-specific M functions programmed per NC line with later synchronisation .
Parameter | %1: | Current value [-]
Block number in the NC program.
%2: | Limit value [-]
Number of axis-specific M functions currently programmed in a NC line with later synchronisation.
%3: |
Maximum number of permissible M functions with late synchronisation per axis and NC line.
Error type | 1, Error message from NC program.
