ABSTRACT:
In a speed correcting device for use in a speed command system such as a numerical controller or a tracer controller in which a movable machine part is driven at a speed corresponding to a speed command value, an error in the moving speed of the movable machine part is removed by detecting the moving speed corresponding to the speed command value being zero and by adding to the speed command value a moving speed correction amount that cancels the detected moving speed.
