Abstract
A 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.
