When the M30 command is executed, the spindle is stopped, the feed is stopped and the cooling system of the tool of the CNC machine tool is turned off. stop is made at the end of working out the corresponding frame during which no information loss

The CNC system returns to its initial state and (or) the executive organs of the machine are set to their initial position.

The initial state of the CNC system provides for a return to the "Start of program" symbol, i.e. provides rewind the CNC program.
