A numerical controller capable of driving a controlled axis in synchronism with a reference axis at a desired speed not restricted by a speed of the reference axis in a path table operation and capable of performing auxiliary function, spindle function and tool wearing compensation function, and changing a position of starting the path table operation of the controlled axis. Data tables are provided storing command positions of controlled axes to be associated with positions of the reference axis and for the auxiliary, spindle and tool wearing compensation functions. The number of pulses of a reference pulse signal from the reference axis is counted and multiplied by an override scale factor and the result is stored in a reference position counter. The controlled axes are driven based on command positions of the controlled axes determined based on the reference position counter, referring to the path and function data tables.
