The rated current indicated on the nameplate of a 15kW inverter or smaller is the current that flows at 4kHz. If the
carrier frequency is set at 12kHz by default, therefore, the rated current needs to be decreased.

Random control is exercised when the motor is operated in a low-frequency range where it produces annoying
magnetic noise.
