Motor drive control device
First Claim
1. 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 comprising:
- a power-running operation voltage setting section that sets a power-running operation 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 is equal to or lower than the power-running operation voltage set by the power-running operation voltage setting section;
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 exceeded the power-running operation voltage set by the power-running operation voltage setting section;
a regenerative operation voltage setting section that sets a regenerative operation voltage of the power supply converter;
a regenerative operation start control section that causes the power supply converter to start a regenerative operation when the direct-current voltage of the power supply converter is equal to or higher than the regenerative operation voltage set by the regenerative operation voltage setting section; and
a regenerative operation stop control section that causes the power supply converter to stop the regenerative operation when the direct-current voltage of the power supply converter is lower than the regenerative operation voltage set by the regenerative operation voltage setting section.
