Kodi kutentha kwa servo kumafunikira chiyani?

Kodi kutentha kwa servo kumafunikira chiyani?

Kuyendetsa bwino komanso kolakwika (CW + CCW); zimachitika kuphatikiza kuwongolera (kugunda + malangizo); Kulowetsa gawo la AB (gawo losiyanitsa magawo, lomwe limagwiritsidwa ntchito kwambiri pakulamulira kwa mawoko).

Pulogalamu yayikulu yoyendetsa servo imagwiritsidwa ntchito kumaliza kumaliza kuyambitsa kwa dongosololi, chizindikiro chowongolera mawonekedwe a LO, ndi kukhazikitsidwa kwa kaundula wa module iliyonse mu DSP.

Ntchito yonse yoyambitsa ntchito ya servo drive ikamalizidwa, pulogalamu yayikulu imayamba kudikirira ndikudikirira kuti pakhale zosokoneza kuti zisinthe ma loop apano ndi liwiro.

Dongosolo losokoneza ntchito limaphatikizira pulogalamu yosokoneza nthawi ya M, pulogalamu yamagetsi yojambula zithunzi zosokoneza, pulogalamu yoteteza mphamvu yamagetsi, ndi pulogalamu yosokoneza yolumikizirana.

Njira zothana ndi zovuta zina zama servo motors

(1) Kuyenda kwamagalimoto: kuyenda kumachitika mukamadyetsa, ndipo chizindikiritso cha liwiro sichikhazikika, monga kuphulika kwa encoder; osalumikizana bwino ndi ma terminal, monga zomangira zomasuka, ndi zina; kayendetsedwe kake kakuchitika molongosoka komanso kolowera kumbuyo Pakadutsa nthawi yamayendedwe, nthawi zambiri imayamba chifukwa chakusiyana kwa chingwe chotumizira chakudya kapena phindu la servo drive limakhala lalikulu kwambiri;

(2) Zokwawa zamagalimoto: zimapezeka makamaka pagawo loyambitsira kapena chakudya chotsika kwambiri, makamaka chifukwa chakuthira koyipa kwa chingwe chotumizira chakudya, phindu lochepa la servo ndi katundu wambiri wakunja. Makamaka, ziyenera kuzindikirika kuti kulumikizana komwe kumagwiritsidwa ntchito polumikizira servo mota ndi kagwere ka mpira, chifukwa cha kulumikizana kovutikira kapena chilema cholumikizira chokha, monga ming'alu, chimayambitsa kuzungulira kwa mpirawo ndi servo mota kuti isagwirizane, zomwe zimapangitsa chakudya Kuyenda kumakhala kofulumira komanso kosachedwa;

(3) Kugwedera kwamoto: Chida cha makina chikamathamanga kwambiri, kugwedera kumatha kuchitika, ndipo ma alamu apano azipangidwa panthawiyi. Mavuto ogwedeza makina nthawi zambiri amakhala mavuto othamanga, chifukwa chake muyenera kuyang'ana zovuta zothamanga;

(4) Kuchepetsa makokedwe amtundu wamagalimoto: Servo mota ikamayenda kuchokera pa torque yomwe idavoteledwa kuti igwire ntchito yothamanga kwambiri, zimapezeka kuti makokedwe achepetsedwa mwadzidzidzi, omwe amayamba chifukwa cha kuwonongeka kwa kutentha kwa magalimoto oyenda ndi kutentha kwa gawo lamakina. Kuthamanga kwambiri, kutentha kwa mota kumakulirakulira, chifukwa chake, katundu wamagalimoto amayenera kufufuzidwa musanagwiritse ntchito servo mota moyenera;

(5) Kulakwitsa kwamagalimoto: Gulu loyendetsa servo likadutsa malo olekerera (KNDSD100 fakitala yoyika PA17: 400, malo opumira kulolerana), servo drive idzawonekera "4 ″ malo okhala ndi alamu yololera. Zifukwa zazikulu ndizakuti: kulolerana kwamachitidwe kachitidwe ndikochepa; dongosolo la servo phindu siloyenera; chipangizo chozindikira malo chaipitsidwa; cholakwika chakuchulukirachulukira kwa chingwe chakudyetsa ndichachikulu kwambiri;

(6) Galimotoyo sizungulira: Kuphatikiza polumikizira kugunda + kwa siginecha kuchokera ku CNC kupita ku servo drive, palinso cholozera chowongolera, chomwe nthawi zambiri chimakhala DC + 24 V yolandirana yamagetsi yama coil. Servo mota satembenuka, njira zodziwikiratu zowunikira ndi izi: fufuzani ngati makina a CNC ali ndi zotulutsa zamagetsi; onetsetsani ngati chizindikiro chololeza chatsegulidwa; onetsetsani ngati mawonekedwe olowetsa / kutulutsa kwa dongosololi amakwaniritsa zoyambira za olamulira azakudya pazenera la LCD; kwa iwo omwe ali ndi mabuleki amagetsi Ma servo mota amatsimikizira kuti mabuleki adatsegulidwa; galimotoyo ndi yolakwika; galimoto ya servo ndiyolakwika; servo mota ndi cholumikizira cholumikizira cholumikizira kapena cholumikizira, etc.

Powombetsa mkota

Powombetsa mkota, kugwiritsa ntchito molondola kwa makina osindikizira a CNC servo drive sayenera kungoyika magawo molondola malinga ndi buku logwiritsa ntchito, komanso kuphatikiza kugwiritsa ntchito tsamba komanso zinthu zomwe zingagwire ntchito mosavuta. Pakugwira ntchito kwenikweni, pokhapokha ndimphamvu zomvetsetsa zaukadaulo ndi maluso othandiza, ogwiritsa ntchito amatha kupeza luso lotha kuyendetsa bwino ma mota ndi ma motors, ndikugwiritsa ntchito ma servo drive ndi ma servo motors bwino.
