Specifications: 1.Ceiling: YDEF--J012 2.Ventilation: axial fan 3.Car wall: oil hair cracked stainless steel. 4. Car door: oil hair cracked stainless steel. 5.Car bottom: PVC floorboard. 6.Operation box,external call: hair cracked stainless steel panel. It adopts complete set of the latest Japanese elevator--purpose microcomputer control and drive technology and fully computer--based intelligent control system,thus realizes multi--microcomputer modularized and networked control.the serial communication greatly improves the responses of elevator and the vector frequency drive system realizes zero-speed direct stopping,which improves operation efficiency and insures perfect comfort and precise floor-alignment.the electronic integrated 32-position microcomputer control system has an extra strong immunity,low trouble ratio and high reliability.its built-in remote monitoring interface can realize,remote diaguosis,remote control and GSM remote control of elevator. Detailed Product Description: (1)Ideal running comfort:driving by the quality vector frequency converten as per the analog-given running curve.the elevator is able to direct stop at the specified position,which improves running efficiency and ensures perfect comfort. (2)Precise floor-alignment:through self-study of shaft parameters,the system correctly stores the distance between the floors in the memory of the microcomputer and during running if provides precise position of the car box through precise calculation and thereby ensures precision of floor-alignment. (3)High reliability:the eletronic integrated 32-position microcomputer control system has a compact structure,extra strong immunity,low trouble ratio and high reliability. (4)Reaization ofpreventive maintenance and protection:the built-in remote monitoring interfacemay make remote diagnosis,remote control,fault memory and GSM remote control of elevator,and find out in advance and immediately eliminate the hidden risks so as to ensure reliable running of elevator. (5)Roomles,gearless passenger elevators. (6)Adopts permanentmagretic synchrorousteeth-less hauling driving technology and device,featuring energy-saving,environmentally friendly,contamination-free,maintenance-free of main unit and compact machine room. (7)Optimal start and brake effect:with the servial load compensation unit.the system can automatically identity different loads and genenate correspording start pre-moment so as to obtain the optimal start and brake effect.
