Abstract: PURPOSE: A method for detecting disconnection of a power cable of a motor is provided to clearly distinguish whether a high voltage is generated due to disconnection between power cables or disconnection between power elements. CONSTITUTION: An inverter(200) monitors a current per a phase supplied to a motor through a current sensor(300) to detect an excessive current. If the excessive current is detected, a power cable disconnection flag is set and the control of the inverter ends. If the excessive current is detected and the power cable disconnection flag is set, it is determined whether the current sensor has an error by monitoring the state of the current sensor. If it is determined whether the current sensor is normal, an increasing gradient of the current per a phase is detected and the detected increasing angle is compared with a set reference gradient.
