<P>PROBLEM TO BE SOLVED: To provide a pulse driving device of a motor-operated valve which can prevent failure of the motor-operated valve, by issuing an alarm in response to an operation state, by accurately grasping the service life of the motor-operated valve based on the driving pulse number transmitted to the motor-operated valve and successively grasping the operation state of the motor-operated valve. <P>SOLUTION: The pulse driving device for driving the motor-operated valve, includes an arithmetic operation means for converting a valve opening signal input to the pulse driving device into a driving pulse and a driving circuit for driving the motor-operated valve based on the driving pulse, and the arithmetic operation means includes a storage means for storing a driving history on driving of the motor-operated valve. <P>COPYRIGHT: (C)2012,JPO&INPIT |
