PURPOSE:To obtain a servo controller by which a high speed operation, a high speed responsiveness and a high accuracy positioning can be realized, by providing a detector switch part for switching a servo-loop control system by a moving residual. CONSTITUTION:A detector switching part 8 inputs a moving residual which has subtracted a command value outputted from an operation command system 1, and a position feedback quantity outputted from a detecting part 6 or 7 in a position control part 2, to the position control part 2. By a value of the moving residual, one of outputs of the detecting part 6 and 7 is selected and inputted. That is, by the moving residual, the position detecting part is switched to a motor position detector or a machine position detector, and the constitution of a servo-system is set to a semi-closed loop controlling system, or a full-closed loop controlling system.
