Abstract
A numerical controller estimates a machining continuable time before a currently controlled motor overheats if an output of the motor exceeds a continuous rated output and predicts respective execution times of command blocks and the machining continuable time for each command block, for a currently running block and its subsequent command blocks. Based on these predicted data, the numerical controller identifies a command block (alarm generation block) in which the motor overheats and a command block (stop block) in which driving control can be safely stopped, within the range of command blocks from the currently running command block to the alarm generation block.
