Patent ID: 7005821

Claim:
A servomotor controller for driving an electric motor type actuator having an electric motor comprising: a serial data-communication section; a receiving processing section for receiving information to a self address fed from a higher level unit via the serial data-communication section; an actuator driving-controlling section for performing a feedback control of a position of an object to be controlled (hereinafter referred to as control object) by driving said electric motor type actuator in order for the position of the control object to be a target value based on the target value of the control object included in the received information and a present position detected by a position detecting section, said present position having a present positional value; an operation inhibiting device to inhibit an operation of said actuator driving-controlling section after difference between said target value and said present positional value being in a previously set allowable range has been detected; and an operation permitting device to release a state that the operation of said actuator driving-controlling section is inhibited based on a forced operation request included in the received information.
