Optimization of the wiring in the sequence control circuit

The sequence control circuit is widely used in 3 phase induction motor control circuit in the industry. There is a problem in the wiring process of the conventional sequence control circuit. Within a limited time it occurs often is missing wiring or wiring mistakes or repeated mistakes. Up to the conduction test from wiring in the control circuit, there is a problem that could not often be perform perfectly. In other words, it means that multiple wiring modifications are required. In this paper, written as a result of the efforts of a lot of trial and error and process improvement experience in the field, in the meantime to overcome the problems of general wiring methods and proposes a new optimal wiring method. Optimal Wiring method is the objective to minimize the problem caused by the wiring part of the wiring between the sequence control circuits. Using the optimal method of wiring to 3 phase induction motor control circuit used in many industries have attempted virtual wiring. This method is possible to identify in advance the path problem analysis on wiring. This method also improves wiring and could reduce the manufacturing cost. Optimum wiring method is also easy to debug by wiring. In addition, in the event of a missing or incorrect wiring, this method can be relatively simple circuit conduction test.
