The bus voltage is high voltage

Bus voltage is the electrical potential measured on a shared conductor, or “bus,” that distributes power or signals between components in a system. Think of it as the voltage on the main highway that feeds electricity to everything connected to it. The term shows up in power grids, industrial motor. Rated voltage is a fixed design parameter used for engineering specifications, whereas bus voltage is the actual, fluctuating voltage present on a bus, varying based on system conditions. Because it's so common, some newer drives try to assist with locating the issue by providing more information about what the drive was doing. DC Bus overvoltage generates a hardware interrupt at 480V.
