Abstract

When a direction command signal indicates a first direction, a signal for causing the other end of the induction load to be connected to a second power supply unit is output as a second control signal. In addition, after a passage of a first predetermined delay time after a first current detection value becomes less than a reference value of a conducting current, a signal for causing the one end of the induction load 5 to be connected to a first power supply unit is output as a first control signal. And, after a passage of a second predetermined delay time after the first current detection value becomes equal to or greater than the reference value of the conducting current, a signal for causing the one end of the induction load to be connected to the second power supply unit is output as the first control signal.
