Abstract

A servomotor control circuit for an air conditioner apparatus of a vehicle includes a drive control section for controlling drive of a servomotor so that the servomotor attains a target stop position, a rotation position change detection section for detecting a change in the rotation position of the servomotor, and an operation limit check section for checking, based on the change in the rotation position of the servomotor, whether the servomotor has attained the operation limit position. The drive control section stops drive of the servomotor without reception of a servomotor drive stop command produced from a main control apparatus, when the servomotor is determined as having attained the operation limit position.
