摘要： A state switching unit switches the state of a motor that has caused an alarm, from an excited state to an un-excited state at an alarm generation timing. A state switch timing setting unit sets a state switch timing of switching the state of a motor other than the motor that has caused the alarm, from an excited state to an un-excited state. This setting is made on the basis of a physical quantity concerning at least one of the motor and a driven body. At the set state switch timing, a state switching unit switches the state of the motor other than the motor that has caused the alarm, from an excited state to an un-excited state.
