PROBLEM TO BE SOLVED: To provide a resolver control device configured to reduce power consumption of a resolver when an inverter is shut down.SOLUTION: A resolver control device includes: an input section which receives a rotation angle detection signal output from a resolver which detects a rotation angle of a motor to be driven by an inverter; a control section which outputs a shutoff signal for shutting off a drive output which drives the inverter; an excitation signal switching section which switches an amplitude of an excitation signal to be applied to the resolver when the control section outputs the shutoff signal; and an amplification factor switching section which switches an amplification factor of the rotation angle detection signal when the control section outputs the shutoff signal. |
