PROBLEM TO BE SOLVED: To provide a positioning control device capable of correcting positional deviation, irrespective of the initial state.SOLUTION: The positioning control device includes a fist deceleration and stop means S05, which simultaneously moves all shafts toward home positions at a first speed and simultaneously decelerates and stops all the shafts, in response to home position dog signal detection of all shafts; a reverse-direction movement means S06, which simultaneously moves all shafts in opposite directions to the home positions at a second speed lower than the first speed; a second deceleration and stop means S08, which detects front ends of all shafts to store a dog front end position of each shaft into a storage part and simultaneously decelerates and stops all shafts; a dog home position dog signal displacement amount calculation means S09, which calculates a home position dog signal displacement amount for each slave shaft on the basis of a master shaft on the basis of the detected dog front end positions of respective shafts and stores the calculated amounts into the storage part; and a home position return means S10 which corrects home positions of respective slave shafts by the home position dog signal displacement amounts to move respective shafts to home positions. |
