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 includes: a power-running operation start voltage setting section that sets a power-running operation start voltage of the power supply converter; a power-running operation start control section that causes the power supply converter to start a power-running operation when the direct-current voltage of the power supply converter has reached the power-running operation start voltage set by the power-running operation start voltage setting section; a power-running operation stop voltage setting section that sets a power-running operation stop voltage of the power supply converter; and a power-running operation stop control section that causes the power supply converter to stop the power-running operation when the direct-current voltage of the power supply converter has reached the power-running operation stop voltage set by the power-running operation stop voltage setting section.
