Abstract

PURPOSE: To reduce positioning time by providing an error portion division correction means for dividing substantially evenly the operational error portion over the time from the start of deceleration to the end of deceleration.
CONSTITUTION: Based on the instructed position a fed from a tape reader 1, a speed fuction generator means 3 generates a speed component b at a predetermined time intervals. Based on the speed component b and operational error portion Z fed from the means 3, an error portion division correction means 11 generates a correction portion d for dividing and correcting the operational error portion Z substantially evenly over the time from the start of deceleration to the end of deceleration. An adder 12 adds the correction portion d to the output b of the means in deceleration time, and a counter 4 counts the output e of the adder 12 and generates an instantaneous instructed position c. A comparator 5 feeds a servo motor 8 with the difference between the instantaneous instructed position c and the present position which is the output of a position detector 9.
