Motor drive control device |
摘要 |
A motor drive control device including a power supply converter that is connected to an alternating-current power supply, a voltage detector that detects a direct-current voltage of the power supply converter, an inverter that is connected to a motor, and an energy storage device that is connected to a direct-current bus that connects the power supply converter and the inverter. The motor drive control device has an operation voltage determination section that determines whether or not the direct-current voltage of the power supply converter is equal to or lower than a power-running operation voltage set by a power-running operation voltage setting section. The motor drive control device has a voltage setting operation control section that causes the power supply converter to start a power-running operation when the direct-current voltage is equal to or lower than the power-running operation voltage, and causes the power supply converter to stop the power-running operation when the direct-current voltage has exceeded the power-running operation voltage.
