<P>PROBLEM TO BE SOLVED: To attain reductions in size and weight of a power supply converter, high efficiency and optimum energy storage apparatus capacity. <P>SOLUTION: The motor drive control apparatus, including an energy storage apparatus connected to a DC bus-bar for connecting the AC power supply side power supply converter with a motor side inverter, is provided with power running operating voltage setting means, power running operating start control means and power running operating stop control means, and regenerative operating voltage setting means, regenerative operating start control means and regenerative operating stop control means. When a DC voltage of the power supply converter reaches a set power running operating start voltage, power running operation is started, and when reaching a set power running stop voltage, power running operation is stopped. When a DC voltage reaches a regenerative operating start voltage, regenerative operation is started, and when reaching a set regenerative operating stop voltage, regenerative operation is stopped. <P>COPYRIGHT: (C)2010,JPO&INPIT |
