I-6.Speed ungqamaniso kunye nokusebenza kolawulo olugqwesileyo;
7.Ukunyuka kobushushu kuncitshiswe ngaphezu kwe-20K.
Iimpazamo eziqhelekileyo zokuguqulela rhoqo?
1. Ngethuba lokulawula i-V / F, i-frequency converter ibika impazamo yokucoca kunye nokwandisa i-torque yokuphakamisa ngokuyimisela ukunyusa i-motor output torque kunye nokunciphisa okwangoku ngexesha lokuqalisa inkqubo;
2. Xa ulawulo lwe-V / F lusetyenziswa, xa ixabiso langoku lemoto liphezulu kakhulu kwindawo elinganisiweyo ye-frequency kunye nesiphumo sokugcina amandla sibi, ixabiso le-voltage elilinganisiweyo lingahlengahlengiswa ukuze kuncitshiswe okwangoku:
3. Ngethuba lolawulo lwe-vector, kukho impazamo yokuzilungisa ngokwakho, kwaye kuyimfuneko ukuqinisekisa ukuba iiparamitha ze-nameplate zichanekile.Bala ngokulula ukuba ubudlelwane obufanelekileyo buchanekile nge-n=60fp, i=P/1.732U
4. Ingxolo ephezulu yomsindo: ingxolo inokuncitshiswa ngokunyusa i-frequency carrier, enokuthi ikhethwe ngokwemilinganiselo ekhuthazwayo kwincwadana;
5. Xa uqala, i-motor output shaft ayikwazi ukusebenza ngokuqhelekileyo: kufuneka iphindwe ngokuzifundela okanye itshintshe imodi yokuzifundela;
6. Xa uqala, ukuba i-shaft ye-output ingasebenza ngokuqhelekileyo kwaye i-overcurrent fault ixelwe, ixesha lokukhawuleza lingalungiswa;
7. Ngethuba lokusebenza, i-overcurrent fault ixelwe: Xa iimodeli ze-motor kunye ne-frequency converter zikhethwe ngokuchanekileyo, imeko ngokubanzi kukugqithiswa kwemoto okanye ukungaphumeleli kwemoto.
8. Impazamo ye-Overvoltage: Xa ukhetha ukucinywa kwe-deceleration, ukuba ixesha lokunciphisa lifutshane kakhulu, linokuphathwa ngokwandisa ixesha lokunciphisa, ukwandisa ukunyanzeliswa kwe-braking, okanye ukutshintsha kwindawo yokupaka yamahhala.
9. Isiphaluka esifutshane ukuya kwisiphene somhlaba: Ukuguga okunokwenzeka kwe-motor, i-wiring engalunganga kwicala lomthwalo wemoto, ukugqunywa kwemoto kufuneka kuhlolwe kwaye i-wiring kufuneka ihlolwe ukuba iphantsi;
10. Impazamo ephantsi: I-converter frequency ayisekelwanga okanye i-motor ayisekelwanga.Jonga imeko yokumisa, ukuba kukho uphazamiseko olujikeleze i-frequency converter, efana nokusetyenziswa kwe-walkie talkies.
11. Ngexesha lokulawula i-loop evaliweyo, iimpazamo zixelwa: izicwangciso zeparameter ye-nameplate engalunganga, i-coaxiality ephantsi yofakelo lwe-encoder, i-voltage engalunganga enikwe i-encoder, ukuphazamiseka kwi-encoder feedback cable, njl.
