The calculation of the module has switched from the drive to the CNC which means that the value of PP4 is not valid and it must be recalculated. On CNC power-up, it checks whether there is a non-integer gear ratio on spindles and rotary axes with module and whether parameter PP76(7)=1 or not. In this case, instead of writing a 0 in that bit, the CNC shows a message indicating that the drive parameters have been set wrong and the value of PP4 must be recalculated with PP76(7)=0.

From the DDSsetup, set parameter PP76(7)=0, validate it and execute the GC6 command so the drive recalculates the new value of PP4. Finally, save the parameters in the flash memory of the drive.
