A controlling apparatus includes a storage unit for storing, for each sampling period, a combination of a primary frequency of connected induction motors and the amplitude of a voltage command value, and a gradient detection unit for calculating a value corresponding to an increase in the amplitude of the voltage command value divided by an increase in the primary frequency, and for outputting a failure signal upon determining, when a result of the division is less than a predetermined reference value, that the plurality of induction motors include at least one induction motor having a phase sequence that includes incorrect wiring with respect to the power converter.
