公式トラブルシューティング手順
Details The equivalent load factor of the spindle motor has exc eeded the set threshold that causes the excess warning. Remedy Change the operation pattern in a way that decreases the spindle motor load. Differential tap cmnd disabled 1131 Details Differential speed tap command has been given alth ough any rotation command has not been input to the reference spindle that is under spindle superimposition control. Synchronous tap command has been given to the refer ence spindle that is under spindle superimposition control. Remedy Cancel the synchronous tapping cycle. Spd clamp in differential tap 1132 Details A tap cycle or synchronous tap cycl e command given to the superimpo sed spindle has caused the spin- dle's actual rotation speed to exceed the spindle clamp speed. Remedy Correct the spindle rotation speed in synchronous tap cycle. Constant surface spd disabled 1133 Details A constant surface speed control command has been gi ven to the reference or superimposed spindle during differential speed tapping under spindle superimposition control. A differential speed tapping command has been issued while constant surface sp eed control is executed on the reference or superimposed spindle that is under spindle superimposition control. Remedy Cancel the synchronous tap cycle or constant surface speed control. Spindle sync cancel error 1135 Details Spindle synchronization cancel command has been issued during rotation of C axis under spindle sync C axis control. G113 (without the address H or D) has been issued during the spindle synchronization for two or more sync sets. Remedy This operation error is cancelled when C axis st ops. Issue a spindle sync cancel command after C axis has stopped. Use G113D or G113H to cancel the spindle synchronization. GB SP sync:Cancel sgnl illegal 1137 Details The guide bushing spindle synchronization temporary cancel signal was turned ON/OFF when the master spin- dle and the guide bushing spindle were in one of the following modes. During rotation (when not stopped) During tap cycle syn chronization mode During spindle synchronization mode During tool-spindle synchronization I (polygon machining) mode During tool-spindle synchronization II (hobbing) mode During spindle C axis control C axis mode During orientation/indexing Remedy Check the ladder program. GB SP sync runs independently 1138 Details The reference spindle was commanded as a spindle related to tool spindle synchronization IC (polygon). The guide bushing spindle was commanded as a synchronous tapping spindle. The guide bushing spindle was commanded as a spindle related to spindle synchronization/tool spindle synchronization I (polygon)/tool spindle synchronizati on II (hobbing). Remedy Check the program.
