    The operation state judgment module is used for judging the operation state of the current multi-station rotary die-cutting machine. The operation state of the multi-station rotary die-cutting machine includes a stop state and a running speed greater than zero and less than or equal to a preset first running speed Threshold low-speed operation state;

    The second forced stop command generation module is configured to generate a second forced stop when the operation state of the multi-station rotary die-cutting machine is in a low-speed operation state with an operation speed greater than zero and less than or equal to a preset first operation speed threshold command, and send the second forced stop command to the cutter shaft motor to control the multi-station rotary die-cutting machine to stop running.
