ELEVATOR CONTROL MECHANISM

摘要

PURPOSE:To provide an elevator control mechanism which can check simply and accurately whether compensation amount of start shock due to unbalanced weight between a car and a balance weight is adequate or not and correct error in compensation amount easily by comparing a detected value of load obtained immediately before start with load calculated during run. CONSTITUTION:A comparison computing section 8 compares and computes a detected value of a rotary encoder E with a reference value to calculate load of a car 1, compares load immediately before start which is detected by a differential transformer 1b with the calculated value, and stores the data obtained when a difference between both values exceeds an abnormality judgement value 8a as an alarm memory 8b.
