This command allows to end the program by rewinding the pointer all the back to the program beginning. This is done in place of a typical M2 command to end a program, and writes a “1” into the GVAR_M30_SCHEDULED_REWIND (5526) global variable to indicate that a rewind will be performed at the end of the program. After the rewind is complete, the 5526 variable will have a “0” written into it, therefore in order to perform a rewind on the next job it is necessary to use the M30 code again.
