<P>PROBLEM TO BE SOLVED: To provide a control device of an elevator for adjusting a difference in a car inside load detecting value, only when supposing that the difference is caused in the car inside load detecting value by a load detector. <P>SOLUTION: This control device includes: a load detecting value zero point abnormality detecting part 16 for determining whether or not a detecting value of a car inside load 7 of the load detector 4 is a predetermined value to be regarded as abnormal or more when a stopping time of a car 1 becomes a predetermined time or more, and fixing zero point abnormality of the detecting value of the car inside load 7 when it is determined that the detecting value is the predetermined value or more; a torque diagnostic operation command part 17 for issuing a travel command to the elevator when the zero point abnormality is fixed by the load detecting value zero point abnormality determining part 16; and a load correction value analyzing part 15 for correcting the detecting value of the car inside load 7 detected by the load detector 4 to a zero point when the car inside load 7 inversely operated by a car inside load inverse operation part 14 is within a predetermined value (the load ratio 1%) regarded as no-load when traveling by the travel command of the torque diagnostic operation command part 17. <P>COPYRIGHT: (C)2013,JPO&INPIT |
