Abstract

PURPOSE:To rprovide an error correcting system for unmerically controlled machine tools, in which error between the driving motor shaft and a member to be controlled is detected and correction for this error is effected outside the loop of driving motor, whereby positioning error due to backlash caused between the driving motor shaft and the member to be controlled can be compensated.
