Ndeupi musiyano uripo pakati pe motion controller ne plc?

Motion controller idhiraivha yakasarudzika yekudzora mashandisiro emotor: semuenzaniso, mota inodzorwa neAC contactor neyekufamba switch uye mota inotyaira chinhu kuti imhanye kusvika panzvimbo yakatarwa uye yobva yadzika pasi, kana kushandisa. iyo nguva relay yekudzora mota kuti itendeuke yakanaka uye yakaipa kana kutendeuka kwechinguva kuti imire uye wozotendeuka kwechinguva kumira.Iko kushandiswa kwekutonga kwekufamba mumunda wemarobhoti uye CNC muchina maturusi akaomarara kupfuura ayo ari mumichina yakasarudzika, ine chimiro chakareruka chekufamba uye inowanzonzi general motion control (GMC).

Zvimiro zvekufamba controller:

(1) Iyo Hardware kuumbwa iri nyore, isa iyo inofamba controller muPC bhazi, batanidza mutsara wechiratidzo unogona kuumbwa nehurongwa;

(2) Inogona kushandisa PC ine hupfumi hwekuvandudza software;

(3) Iyo kodhi yekufambisa inodzora software ine yakanaka yepasirese uye kutakura;

(4) Kune akawanda mainjiniya anogona kuita basa rekusimudzira, uye budiriro inogona kuitwa pasina kudzidziswa kwakawanda.

Chii chinonzi plc?

Programmable logic controller (PLC) idhijitari arithmetic mashandiro emagetsi sisitimu yakagadzirirwa kushandiswa munzvimbo yeindasitiri.Inoshandisa inorongeka ndangariro umo mirairo yekuita mashandiro akadai seane musoro mashandiro, kutevedzana kwekutonga, nguva, kuverenga uye arithmetic mashandiro anochengetwa, uye mhando dzakasiyana dzemichina michina kana maitiro ekugadzira anodzorwa kuburikidza nedhijitari kana analog yekupinda nekubuda.

Zvimiro zve plc

(1) Kuvimbika kwakakwirira.Nekuti PLC inowanzo shandisa single chip microcomputer, saka yakakwira kusanganisa, yakasanganiswa neinopindirana yekudzivirira dunhu uye yekuzviongorora basa, inovandudza kuvimbika kweiyo system.

(2) Easy programming.PLC programming inoshandisa relay control ladder diagram uye command statement, nhamba yacho ishoma pane microcomputer rairo, mukuwedzera kune yepakati nepamusoro giredhi PLC, iyo general diki PLC ingangoita 16. Nekuda kwemanera dhayagiramu mufananidzo uye nyore, saka nyore kugona, nyore kushandisa, kunyangwe haidi hunyanzvi hwekombuta, inogona kurongwa.

(3) Flexible configuration.Nekuti PLC inotora chivakwa chekuvaka, mushandisi anongoda kusanganisa chete, obva agona kushandura basa uye chiyero cheiyo control system, saka, inogona kuiswa kune chero control system.

(4) Pedzisa kuisa / kubuda basa modules.Imwe yemabhenefiti makuru ePLC ndeyekuti kune akasiyana masaini emumunda (akadai seDC kana AC, shanduko yehuwandu, huwandu hwedhijitari kana huwandu hweanalog, voltage kana zvazvino, nezvimwewo), kune matemplate anowirirana anogona kubatanidzwa nemidziyo yemumunda yeindasitiri (yakadai. semabhatani, ma switch, sensing azvino ma transmitters, motor starters kana control mavharuvhu, etc.) zvakananga, uye akabatana neCPU motherboard kuburikidza nebhazi.

(5) Kuiswa nyore.Kuenzaniswa nekombuta system, kuisirwa kwePLC hakudi kamuri yakakosha, uye haidi matanho akasimba ekudzivirira.Kana yashandiswa, mudziyo wekuona chete uye I/O interface terminal yeactuator uye PLC yakabatana nemazvo, saka inogona kushanda zvakajairwa.

(6) Kukurumidza kumhanya.Nekuti PLC kutonga kunodzorwa nehurongwa hwekuita, saka ingave kuvimbika kwayo kana kumhanya kumhanya, iyo relay logic control haigone kuenzaniswa.Mumakore achangopfuura, kushandiswa kwemicroprocessor, kunyanya nehuwandu hukuru hwe single chip microcomputer, kwakawedzera zvakanyanya kugona kwePLC, uye musiyano uripo pakati pePLC nemicrocomputer control system uri kuita diki uye diki, kunyanya iyo yepamusoro-giredhi PLC yakadaro.

Musiyano uripo pakati pekufamba controller uye plc:

Motion control inonyanya kusanganisa kutonga kwe stepper mota uye servo mota.Iyo yekudzora chimiro kazhinji: control mudziyo + mutyairi + (stepper kana servo) mota.

Iyo yekudzora mudziyo inogona kuve PLC system, inogona zvakare kuve yakakosha otomatiki mudziyo (senge inofamba controller, inofamba inodzora kadhi).PLC sisitimu semudziyo wekudzora, kunyangwe iine kuchinjika kwePLC system, imwe dhizaini, asi kune yakanyanya kurongeka, senge - interpolation control, zvinonzwisisika zvinodiwa pazvinenge zvakaoma kuita kana hurongwa hwakaoma, uye mutengo ungave wakakwira. .

Nekufambira mberi kwetekinoroji uye kuunganidza, inofamba inodzora inobuda panguva chaiyo.Inosimbisa mamwe mabasa akajairika uye akakosha ekudzora mafambiro mairi - senge mirairo yekududzira.Vashandisi vanongoda kugadzirisa uye kufonera aya anoshanda mabhuroki kana mirairo, izvo zvinoderedza kuoma kwehurongwa uye zvine zvakanakira mukuita uye mutengo.

Zvinogona zvakare kunzwisiswa kuti kushandiswa kwePLC chinhu chakajairwa chekufamba chinodzora mudziyo.Motion controller yakakosha PLC, izere - nguva yekudzora kufamba.
