Beschreibung
Zusammenfassung:	In a spindle control system in which a pulse coder is coupled with a spindle; a pulse train signal, derived from the pulse coder upon each rotation of the spindle through a predetermined rotational angle, is converted into an analog signal corresponding to the actual rotational speed of the spindle; and the analog signal is compared with a commanded speed signal to drive the spindle at the commanded speed. Upon application of a command for stopping the spindle at a predetermined position, a predetermined numerical value is set in an error register in accordance with a specified position signal from the pulse coder, the pulse train signal from the pulse coder is fed back to the error register, and the rotational position of the spindle is controlled with a signal corresponding to the content of the error register.
