PROBLEM TO BE SOLVED: To provide a positioning control unit which enables high-precision fast positioning. SOLUTION: In the positioning controller 100 which outputs the number of pulses outputted from an encoder 10 as a current position to a servo amplifier 8, the distance from a positioning start position to a target position as a movement distance, a position calculated from the movement distance, rotation characteristics of a motor, and a specific acceleration/deceleration time as a command position, and the multiplication result obtained by the difference between the command position and current position by previously set coefficients as an actual command, three in-movement, in-settlement, and in-stop control periods are set, and the said coefficients are provided corresponding to the three control periods and selectively switched corresponding to the three control periods. |
