PROBLEM TO BE SOLVED: To provide a highly reliable motor-driven valve control device by preventing a motor-driven valve from getting out of order depending upon the number of times of execution of initialization processing.SOLUTION: There is provided a control device 11 for a motor-driven valve 9, including a valve body controlling a flow rate of fluid and a motor (stepping motor) 8 driving the valve body, which includes valve opening control means (a microcomputer 11b and a stepping motor driver 11d) of controlling opening of the motor-driven valve, initialization control means (the microcomputer 11b and the stepping motor driver 11d) of performing initialization processing on the motor-driven valve, and storage means (EEPROM) 11e. the number of times of execution of the initialization processing being stored in the storage means. The control device further includes communication means (LIN transceiver 11c) of transmitting and receiving signals, and can output the number of times of execution of initialization processing stored in the storage means. A motor-driven valve device 12 can be configured using the motor-driven valve 9 to which the motor-driven valve control device 11 is fitted in one body. |
