<P>PROBLEM TO BE SOLVED: To easily detect a balance error value more frequently in a short time. <P>SOLUTION: A balance device for detecting a car-inside load is used to control drive of a car hoisting motor. A balance error detecting means 22 is provided so as to detect a torque command value Ts when releasing brake in the car stop condition as a balance error torque value Te due to a balance error of a balance device by outputting a torque command output signal Tsew of the torque to be generated by the motor, which is obtained by computing a torque command value Ts obtained from a difference between a speed command value Sc for the motor and real speed value Sr and a load torque value Tw based on a balance detection value Vw of the balance device expressing the car-inside load, to the motor for control. A torque computing means 29 is provided to output the torque signal output signal Tsew, which is obtained by computing the torque command value Ts and a load compensation torque value Tew obtained by correcting the load torque value Tw with the balance error torque value Te, to the motor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
