PROBLEM TO BE SOLVED: To provide a method of detecting a disconnection state of a power cable in an inverter system, capable of detecting the disconnection state of the power cable through software implementation without additional hardware equipment.SOLUTION: A method of detecting a disconnection state of a power cable in an inverter system includes the steps of: detecting the disconnection state of a first power cable by using a difference value between a battery voltage and a DC-link voltage; detecting the disconnection state of a second power cable by using a driving speed, a phase current instruction value, and an actual phase current value of a motor; and stopping driving of the motor if one of the first and second power cables is detected as being disconnected. |
