<P>PROBLEM TO BE SOLVED: To easily adjust installation operation of an elevator system incorporating an electric power conversion part 7 having an electric power regenerative function irrespective of temporarily provided three-phase power supply 2. <P>SOLUTION: This elevator controller incorporating the electric power conversion part 7 having a function for feeding back regenerative electric power of a motor 12 having load onto a power supply side 1 is provided with a regenerative electric power consumption part 30 for consuming direct current regenerative electric power output from an inverter 10 in the electric power conversion part 7 onto a converter 8 side when performing regenerative operation of the motor 12 and a switch circuit (a socket 29) inserted between the regenerative electric power consumption part 30 and a converter side output end of the inverter 10. While the temporarily provided three-phase alternating current power supply instead of three-phase alternating current power supply having rated capacity is connected with a power supply side end of the electric power conversion part, electric power conversion operation from direct current to alternating current in a converter 8 in the electric power conversion part is stopped and the switch circuit is closed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
