| description | PROBLEM TO BE SOLVED: To provide a method and a system for the emergency stop of a servo position controller which allows the servo position controller to stop with deceleration similar to a case that a position control loop is substantially broken without requiring a position matching processing in the case of recovery. SOLUTION: This servo position control system is provided with a position control loop to apply negative feedback control to the position of a controlling object on the basis of a target position instruction and to apply the negative feedback control to the speed of the positional change of the controlling object, and is further provided with a detecting circuit 11 to detect depression of an emergency stop button and a positional instruction generating circuit 10 to make the positional instruction retract by a constant speed deviation by the output of the detecting circuit 11. |
