This article is to study small freight elevator based on PLC control and frequency invertor speed control. Firstly , realize the design of the small freight elevator system。 Secondly, the PLC、invertor、motor、alarm、display and other hardware parts design and the use of GX Developer software programming and GX Simulator software simulation; Finally, complete the test of the whole system. This design than traditional elevator system more reliability、stability、functional and low energy, and more broad market!KEYWORDS: Elevator; Programmable logic controller; Inverter...
