PROBLEM TO BE SOLVED: To provide a numerical controller capable of easily identifying a change in an operating environment which causes incompletion of starting the numerical controller in the case where changes have been made as to settings for starting the numerical controller, thereby preventing the settings from being changed to cause failure of starting.SOLUTION: A numerical controller 100 comprises: a startable setting storage area 210 for storing startable start-up settings; and an erroneous setting detection database 220 for storing start-up setting values that cause incompletion of starting. If starting completes at start-up, current start-up settings are stored in the startable setting storage area 210 as startable settings. If starting does not complete, start-up setting values that caused incompletion of starting are entered in the erroneous setting detection database 220, the current settings are reconstructed to startable settings, and the numerical controller is restarted. When start-up settings are changed, the erroneous setting detection database 220 is searched. If the same start-up settings as the changed start-up settings are retrieved, the retrieved start-up settings are output.SELECTED DRAWING: Figure 3 |
