Abstract

PURPOSE:To shorten a time required for searching the origin by a method wherein, when the state of an origin detecting switch changes, a servo system is displaced at high speed from the detection of this change in the state to the vicinity of the origin, and at low speed from the vicinity of the origin to the origin. CONSTITUTION:In the case when displacement is made at high speed at first in the direction wherein target position on the coordinates increase, a control means 4 detects a position whereat the state of a holding means 3 changes. Then, in the case when the displacement is made from said position of change in the direction wherein the target positions on the coordinates decrease, a displacement signal for making the displacement at high speed to the position whereat the state of the holding means 3 changes, i.e. the position in the vicinity of the origin, and at low speed from the vicinity to the origin to the origin is delivered to a controller of a servo system. By this method, a timer for searching is shortened and the final searching for the origin is made precisely.
