More than 7 M functions have been sent to the PLC without synchronization, or more than 7 H functions, and the PLC has not had time to read them (MINAEENDW has not elapsed). If they are in different blocks, but are separated by a movement block that is executed in a short time, the CNC groups the functions and if they are more than 7 M or 7 H it gives this warning. The PLC ignores the functions shown in the warning.

There can be no more than 7 M functions without synchronization or 7 H functions in the same block.
