PURPOSE:To prevent the spread of trouble and also enable a trouble generation part to be easily identified by providing a motor control part which controls a driver part based on motor vs temperature information and a demand for action to be received from an outer device. CONSTITUTION:A control part 1 controls an action signal so that motor vs temperature information 16 is set within a range previously designated, based on motor vs temperature information and a demand for action 10. On the other hand, ambient temperature information 15 from an ambient temperature detection part 11 is compared with the temperature information of a motor 4 given as ambient temperature signal 13 converted by parameters and a temperature signal 8 from a temperature detection part 3. Then the comparison results are output to the control part 1 as motor vs temperature information 16. In addition, if it is interpreted that the temperature of the motor 4 is high beyond an allowed level, based on motor vs temperature information, the control part 1 notifies a host computer of an alarm state by connecting an alarm signal 9 to inhibit the drive of the motor 4. Thus the motor 4 is prevented from running with an overload and the host computer is notified of an alarm state before the spread of trouble. Consequently, any trouble can be detected easily. |
