Interrupting a job
By removing the start bit, the current storage/retrieval process can be interrupted. To ensure a stop true to path of the current job during an optimized synchronization process (synchronization distances of the telescope and the belt greater than or equal to 0), such an interruption becomes only active when the box has reached the synchronous point. If no optimized synchronization process is performed, such an interruption becomes active directly. From standstill, the interrupted job can be continued by setting the start bit again.
