MACHINE STATE CONFIRMATION INPUT SIGNAL MANAGING DEVICE IN NUMERICAL CONTROLLER

摘要

PROBLEM TO BE SOLVED: To surely manage an input signal from the outside part such as a limit switch for confirming a machine state of a numerical controller even during the assembly adjusting work of a machine tool. SOLUTION: A signal from a limit switch 1 is rewritten by an input signal rewriting part 10 according to rewriting information inputted from a keyboard 6. This rewritten input signal is displayed at a display device 5 so as to be always confirmed by an operator. Also, the contents of the rewriting information stored in a rewriting information storing part 8 are announced by voice from a speaker 13.
