Title:
ELECTRICALLY OPERATED VALVE CONTROL DEVICE, AND ELECTRICALLY OPERATED VALVE DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2019/130928
Kind Code:
A1
Abstract:
Provided are an electrically operated valve control device and an electrically operated valve device provided with the same, with which it is possible for a deterioration in the accuracy of controlling a degree of opening as a result of a loss of synchronization to be reliably prevented. Upon detecting a loss of synchronization, whereby a current degree of opening of an electrically operated valve (9) differs from a degree of opening stored in an electrically operated valve control device (11), an initialization request signal is output to the outside (to an air conditioner ECU (16), which is a system control device).
