Cage position control unit null of sky parking

摘要

PURPOSE:To reduce the cost of equipment, etc., by a method in which a winder is controlled on the basis of data on the present position obtained by detecting the turning amount of the main rope driving shaft of an elevator winder and data on a target position. CONSTITUTION:A turning amount-detecting pulse oscillator 1 is set on the winder driving shaft of a vehicle-mounting cage. A cage is lifted, the pulse of each stage is counted by a pulse meter 4 and put in CPU 5 to set up a target value. A pulse count value program corresponding to each stage and data on deceleration distance are put in CPU 5 from a program loader 7. A housing place is designated by an operator 11, a winder is driven, and the present position and the designated position by pulse are calculated for comparison in CPU 5. The cage is stopped at a desired position by a controller 6. The cost of equipment, test operation, and maintenance can be greatly cut down without use of limit switch.
