The invention provides a numerical controller controlling acceleration and deceleration of respective control axes up to command speeds. Initial speeds in the move commands for respective control axes at servo-on are determined according to parameter setting, or the comparative relationship or difference in speed among the actual speeds of the control axes so that difference in position between the control axes does not increase as the move commands are executed after the servo-on. The actual speeds of the control axes are set as initial speeds in the move commands, and a target axis is specified on the basis of the comparative relationship among their actual speeds and the other control axes are accelerated or decelerated at the acceleration or deceleration rate specified in the move commands to attain the position and speed of the target axis, so that differences in position and speed among the control axes are gradually decreased as the move commands are executed after the servo-on, thereby preventing abru
