ABSTRACT:
In numerical controls of machine tools, the downwards (lengthwise) sum of the programmed information of each system program memory (SP1) is stored in an additional memory. For later checking of the memory contents, the downwards sums of the respective memories on the control side are formed and are compared with the stored information. If a sum deviates, a trouble signal is given out as an indication of the defective memory.
