1, 3# of area of finishing of factory of medium plate of limited company of combination of foreword Nanjing iron and steel cuts way of the roller before machine, it is the roller line that by 20 stand-alone Chan Gun forms one group, to make sure dependability and production are successional, the electric machinery of the electric machinery of the odd serial number that this groups of roller and even serial number parts to give birth to EV2000-4T0550G transducer to control by 2 Ai Mo, the output line of 2 transducer introduces case of 2 electric machinery allocation respectively, repass installs the corresponding electric machinery breaker in box of electric machinery allocation, make the electric machinery of 10 odd serial number and 10 electric machinery of even serial number divide 2 groups of paralell connection to move. By January 2006, the transducer that dominates electric machinery of even serial number appears breakdown, make rhythm of finishing region production slows, need rapid platoon to check, processing breakdown, make production returns to normal. 2, the breakdown code that breakdown platoon checks the transducer that reachs the spot to handle occurrence trouble to operate face plate to show is E019, and press restoration key cannot remove this trouble, the breakdown that transducer stops working; classics to check breakdown code is E019 detects for electric current circuit breakdown. The voltaic detecting element of EV2000-4T0550G transducer is suddenly Er component, if attached drawing place is shown,suddenly Er component installs sketch map, the inversion circuit share of transducer was drawn only in attached drawing, through H1, H2 and H3 component of these 3 suddenly Er detects the three-phase of transducer exports electricity, via relevant circuit changeover becomes linear voltage signal, repass magnifies comparator inputs CPU, CPU judges transducer to whether pass electricity according to this signal size, if output electric current to protect set value more than, criterion breakdown blocks protective circuit is made, signal of block IGBT pulse, realize transducer shed protective function too. Sketch map of installation of suddenly Er component says transducer of attached drawing EV2000-4T0550G commonly, transducer can connect a line as a result of control plate or plug-in unit becomes loose, attaint of voltaic detecting element and electric current detect enlarge comparator is unusual bring about electric current to detect circuit breakdown, the first kind of circumstance needs to check control plate to have even line or plug-in unit without shake; to the 2nd kind of circumstance needs to change or handle; of voltaic detecting element the 3rd kind of circumstance detects for electric current IC chip or power source of IC chip job are unusual, but through changing auxiliary power source solves IC chip or repair transducer. Cut off transducer to input power source, open transducer front shroud, after waiting for straight discharge drifting end to end, examination control plate joins line and plug-in unit, all do not have become loose and unusual appearance. Check suddenly Er component to whether damage further, the suddenly Er component of EV2000-4T0550G transducer is even the line plug, socket structure, unplug above all the outlet on H3, after new power transmission, operation face plate shows E019; again power cut, after waiting for discharge to end, unplug the outlet on H2, after power transmission, operation face plate still shows E019; new power cut, after waiting for discharge to end, unplug the outlet on H1, insert respectively on the outlet on H2, H3, the breakdown on operation face plate shows disappear, it is normal to show, demonstrative electric current detects circuit trouble removal. Control fashion as a result of adoption V/f ≈ C, it is means of control of a kind of open loop, means of voltaic check line basically finishs electric current to detect, electric current shows and shed protective function too, and do not share control truly, so, unplug the Huoer that already damaged the outlet on component H1, transducer still can return to normal the job, just fall in the circumstance with primary changeless line, use H2 and H3 component of two suddenly Er undertakes electric current detects, the voltaic value that when than using 3 Huoer component undertakes electric current detects, the voltaic value that transducer indicates indicates is little. Is those who need an attention: ? Hill of box of children's hair of Yi Gan lamp spends cutting of the feet of  of Xi of coal of Long A Chinese-style unlined garment] the observation that through be in the spot has, platoon checks?3 of  of  of  of stern of act of Lu of those of Mao  locust, last word, analysis, and appropriate, reasonable processing, inside cutty time, removed transducer trouble quickly, make finishing area produces rhythm to return to normal quickly, assured manufacturing on the rails.
