Chowongolera choyenda ndi chowongolera chapadera kuti chiwongolere magwiridwe antchito amotor: mwachitsanzo, mota imayendetsedwa ndi cholumikizira cha AC ndi chosinthira chapaulendo ndipo mota imayendetsa chinthucho kuti chithamangire pamalo omwe atchulidwa kenako ndikutsika, kapena kugwiritsa ntchito. nthawi yopatsirana kuwongolera mota kuti itembenuke zabwino ndi zoyipa kapena kutembenukira kwakanthawi kuyimitsa ndikutembenuka kwakanthawi kuyimitsa.Kugwiritsiridwa ntchito kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kamwemwebumwemwemwemwemwedwe kuyi lugha ikuyiyitsire

Mawonekedwe a motion controller:

(1) The hardware zikuchokera ndi losavuta, ikani zoyenda Mtsogoleri mu basi PC, kulumikiza mzere chizindikiro akhoza wapangidwa ndi dongosolo;

(2) Angagwiritse ntchito PC ali wolemera mapulogalamu chitukuko;

(3) Khodi ya pulogalamu yowongolera zoyenda ili ndi chilengedwe chonse komanso kusuntha;

(4) Pali mainjiniya ambiri omwe angathe kugwira ntchito zachitukuko, ndipo chitukuko chingathe kuchitika popanda maphunziro ambiri.

Kodi plc ndi chiyani?

Programmable logic controller (PLC) ndi digito ya masamu pakompyuta yomwe idapangidwira kuti igwiritsidwe ntchito m'mafakitale.Amagwiritsa ntchito kukumbukira kosinthika komwe malangizo oti azichita zinthu monga zomveka, kuwongolera motsatana, nthawi, kuwerengera ndi masamu amasungidwa, ndipo mitundu yosiyanasiyana ya zida zamakina kapena njira zopangira zimayendetsedwa kudzera muzolowera digito kapena analogi ndikutulutsa.

Makhalidwe a plc

(1) Kudalirika kwambiri.Chifukwa PLC nthawi zambiri imagwiritsa ntchito kachipangizo kakang'ono kakang'ono, kuphatikiza kwakukulu, kuphatikizidwa ndi gawo lodzitchinjiriza ndi ntchito yodzizindikiritsa, kumapangitsa kudalirika kwadongosolo.

(2) Mapulogalamu osavuta.Pulogalamu ya PLC imagwiritsa ntchito chithunzithunzi cha makwerero a relay ndi ndondomeko ya lamulo, chiwerengerocho ndi chochepa kwambiri kuposa malangizo a microcomputer, kuwonjezera pa PLC yapakati ndi yapamwamba, PLC yaying'ono pafupifupi 16. Chifukwa cha chithunzi cha makwerero ndi chophweka, chophweka. kuti adziwe, yosavuta kugwiritsa ntchito, ngakhale safuna ukatswiri kompyuta, akhoza anakonza.

(3) Kusintha kosinthika.Chifukwa PLC imatengera mawonekedwe omangira, wogwiritsa ntchito amangofunika kuphatikiza, ndiye amatha kusintha magwiridwe antchito ndi kukula kwa dongosolo lowongolera, chifukwa chake, atha kugwiritsidwa ntchito panjira iliyonse yowongolera.

(4) Malizitsani zolowetsa / zotulutsa ntchito.Ubwino umodzi waukulu wa PLC ndikuti pamasinthidwe osiyanasiyana am'munda (monga DC kapena AC, kuchuluka kwakusintha, kuchuluka kwa digito kapena kuchuluka kwa analogi, magetsi kapena zamakono, ndi zina), pali ma tempulo ofananira omwe amatha kulumikizidwa ndi zida zakumunda zamakampani (monga monga mabatani, ma switch, ma transmitters apano, zoyambira ma motor kapena ma valve owongolera, ndi zina) mwachindunji, ndikulumikizidwa ndi bolodi ya CPU kudzera m'basi.

(5) Easy unsembe.Poyerekeza ndi makina apakompyuta, kuyika kwa PLC sikufuna chipinda chapadera, komanso sikufuna njira zotetezera.Mukagwiritsidwa ntchito, chipangizo chodziwikiratu chokha ndi cholumikizira cha I / O cha actuator ndi PLC chimalumikizidwa bwino, ndiye kuti chimatha kugwira ntchito moyenera.

(6) Liwiro lothamanga.Chifukwa kuwongolera kwa PLC kumayendetsedwa ndi pulojekitiyi, kotero ngati kudalirika kwake kapena kuthamanga kwake, ndikuwongolera kwamalingaliro sikungafanane.M'zaka zaposachedwapa, ntchito microprocessor, makamaka ndi chiwerengero chachikulu cha single Chip microcomputer, kwambiri patsogolo luso la PLC, ndi kusiyana PLC ndi microcomputer dongosolo kulamulira ang'onoang'ono ndi ang'onoang'ono, makamaka mkulu-kalasi PLC ndi choncho.

Kusiyana pakati pa motion controller ndi plc:

Kuwongolera koyenda kumakhudzanso kuwongolera kwa stepper motor ndi servo motor.Kapangidwe kowongolera nthawi zambiri ndi: chida chowongolera + driver + (stepper kapena servo) mota.

Chipangizo chowongolera chikhoza kukhala PLC dongosolo, chingakhalenso chida chapadera chodziwikiratu (monga chowongolera choyenda, khadi yowongolera).Dongosolo la PLC ngati chida chowongolera, ngakhale chili ndi kusinthasintha kwa dongosolo la PLC, kusinthasintha kwina, koma mwatsatanetsatane kwambiri, monga - kuwongolera kutanthauzira, zofunikira zomveka pamene kuli kovuta kuchita kapena kupanga mapulogalamu kumakhala kovuta kwambiri, ndipo mtengo ukhoza kukhala wokwera. .

Ndi kupita patsogolo kwaukadaulo komanso kudzikundikira, chowongolera choyenda chimatuluka panthawi yoyenera.Imalimbitsa ntchito zina ndi zapadera zowongolera momwemo - monga malangizo omasulira.Ogwiritsa ntchito amangofunika kukonza ndikuyitanitsa midadada yogwira ntchito kapena malangizo, zomwe zimachepetsa zovuta zamapulogalamu ndipo zimakhala ndi zabwino pakuchita ndi mtengo.

Zitha kumvekanso kuti kugwiritsa ntchito PLC ndi chipangizo chodziwika bwino chowongolera kuyenda.Zowongolera zoyenda ndi PLC yapadera, nthawi yonse yowongolera kuyenda.
