摘要：PURPOSE:To raise the accuracy in a switching point by providing an origin return function on a position control part, and executing an orienting operation at the time of switching a speed loop to a position loop, as an origin return operation of the position loop. CONSTITUTION:To a motor 1, a speed detector 2 is installed, and to its rotation axis, a position detector 3 is attached. A controller of the motor 1 is constituted of a speed control part 4, a position control part 6, and a changeover switch 7. In this case, the position control part 6 has an origin return function for returning the rotation axis to an origin position prior to a position loop control, at the time of switching a speed loop to a position loop. Accordingly, an orienting operation at the time of switching to the position loop is executed as an origin return operation of the position loop. In such a way, an orientation control part for switching the speed loop to the position loop becomes unnecessary, and an error can be eliminated.
