摘要： PROBLEM TO BE SOLVED: To improve control accuracy of an electromagnetic driving valve by shortening the transfer time of a target current value from a control means to a drive means.
SOLUTION: This device includes the control means 8 for setting the target current value to be supplied to respective electromagnetic coils and a drive means 9 for exciting and driving the electromagnetic coils based on the target current value set by the control means 8. The control means 8 transfers the target current value to the electromagnetic coils to be excited, identifiers to identify that the target current value corresponds to which opening or closing electromagnetic coil in the electromagnetic driving valves 4a, 4b to the driving means in a sequence preset by serial communication. The drive means 9 selects the electromagnetic coil to be excited based on received identifier, excites and drives the electromagnetic coil corresponding to received identifiers based on the newly received target current value, thus stopping excitation to the electromagnetic coils which do not correspond to the received identifiers.
