費電力等を効率的、経済的にするためである。As is known in Japanese Patent Laid-Open No. 2-204290, a cage type elevator has a car connected to one end of a main rope hung on a sheave and a counterweight connected to the other end. In this configuration, the weight of the counterweight is such that the weight on the car side (the weight of the car body and the passengers) and the weight on the counterweight side are balanced when approximately half the passengers in the car are in the car. Is set. This is to make the capacity and power consumption of the electric motor that drives the elevator and the control device that drives the electric motor efficient and economical.

転させた時の電動機電流を測定しつつ相互の電流値の差
を０に近づけるように釣合錘を増減していた。The weight of the counterweight is adjusted when the elevator is installed. For this adjustment, the electric currents of the motors when the elevator is raised and lowered are measured, and the difference between the mutual current values approaches 0. The weight was increased or decreased.

いという欠点があった。As described above, the conventional elevator device increases or decreases the counterweight when adjusting the weight of the counterweight, and raises or lowers the elevator each time to reduce the difference in the motor current value during each operation to zero. It is checked whether or not it is approaching, and when the value deviates from zero, the increase and decrease of the weight and the raising and lowering of the elevator will be repeated again, which requires time and labor for the work, and it causes dangerous work. There was a point. Further, in recent years, induction motors have been used as elevator driving motors, and in the case of a low current frequency, there is a drawback that the lower limit of the frequency characteristics of the ammeter is exceeded and an accurate current value cannot be measured.
