Abstract

In a servomotor controller, when a comparing circuit (70) detects that a position of an object to be controlled has been achieved to a target position, an operation inhibiting signal generating section (71) supplies an operation inhibiting signal (71a) to an operation permitting/inhibiting signal-processing section (66), and obtains an operation stopped state of an H bridge-driving processing section (67) for controlling driving of a motor. A LIN communication processing section (61) receives information to a self address supplied from a superordiante device, and outputs a forced operation (recovery) request (61R) in the received information. The operation state of the H bridge-driving processing section (67) is obtained through an operation permitting trigger signal generating section (65) and the operation permitting/inhibiting signal-processing section (66) through the H bridge-driving processing section (67). The motor is accordingly driven, and the feedback control based on the difference between the target position and the present position is restarted.
