PLC Servo Motor Control: Njira Zitatu Zofotokozedwa ndi Zitsanzo

PLC Servo Motor Control: Njira Zitatu Zofotokozedwa ndi Zitsanzo

I. Torque Control

Pakuwongolera ma torque, ma torque agalimoto amayikidwa kudzera pa siginecha yakunja ya analogi kapena popereka mtengo ku adilesi inayake. Mwachitsanzo, ngati 10V ikufanana ndi 5Nm, chizindikiro cha 5V chingapangitse torque kukhala 2.5Nm. Galimotoyo idzayendetsa katundu wochepera 2.5Nm kutsogolo, kugwira pa 2.5Nm, ndi kubwerera kumbuyo pansi pa katundu wopitirira 2.5Nm. Torque imatha kusinthidwa munthawi yeniyeni posintha siginecha ya analogi kapena kukonzanso mtengo wa adilesi kudzera kulumikizana.

II. Kuwongolera Udindo

Kuwongolera malo kumaphatikizapo kuyika liwiro la mota ndi kuchuluka kwa mayendedwe akunja ndi malo ake ndi kuchuluka kwa ma pulse. Ma servos ena amalola kuthamanga kwachindunji ndi kugawa kwamtengo wamalo kudzera pakulankhulana. Chifukwa cha liwiro lake lolondola komanso kuwongolera malo, njirayi ndi yabwino pamakina oyika.

III. Kuwongolera Mayendedwe

Kuwongolera kwa liwiro kumatha kuchitika pogwiritsa ntchito ma siginecha a analogi kapena ma pulse frequency. Mukagwiritsidwa ntchito ndi chipika chowongolera chakunja cha PID, kuwongolera kwa liwiro kumathanso kuyimitsa, malinga ngati malo agalimoto kapena malo onyamula abwezeredwa kwa wowongolera kuti awerengeredwe.

Chithunzi cha SINAMICS V90 System

SINAMICS V90 imapereka mitundu iwiri kuti igwirizane ndi mapulogalamu osiyanasiyana:

Mtundu wa Pulse:Zophatikizidwa ndi pulse, analog, USS/MODBUS ntchito.

PROFINET Mtundu:Zapangidwira kulumikizana kwa PROFINET.

Mtundu wa pulse umathandizira magwiridwe antchito amkati, opereka mitundu ngati kuwongolera malo, kuwongolera liwiro, ndi kuwongolera ma torque.

Tanthauzo la Chiyankhulo

Mtundu wa pulse umagwiritsa ntchito mawonekedwe a PTI okhala ndi zosintha zosasinthika zomwe zimagwirizana ndi machitidwe wamba. Njira imodzi yokha yolumikizira ma pulse ingagwiritsidwe ntchito panthawi imodzi, pomwe ma siginecha ena owongolera amatha kuperekedwa momasuka ku ma terminals a digito I/O. Mphamvu yamagetsi ya 24V yomwe ikuwonetsedwa pazithunzi zamawaya ndi ya SINAMICS V90. Zizindikiro zonse za PTO ziyenera kulumikizidwa ndi wowongolera pogwiritsa ntchito gwero lamagetsi lomwelo la 24V. Zolowetsa digito zimathandizira mitundu yonse ya NPN ndi PNP.

Kulumikiza kwa Brake Cable kwa SINAMICS V90

Kulumikizana kwa chingwe cha brake komwe kukuwonetsedwa kumangogwira pagalimoto ya V90 400V. Kuyendetsa kwa V90 200V kumafuna kulandila kwakunja kwa ma brake a motor.

Zithunzi za Wiring System

Pagalimoto ya V90 200V, cholumikizira chakunja chimafunikira kuti mulumikizane ndi mabuleki agalimoto.

Kuyendetsa kwa PTI kumagwirizanitsa ndi relay kudzera pa chingwe cha setpoint, pamene PROFINET drive imagwiritsa ntchito chingwe cha I / O.

Kwa PROFINET 200V kuwongolera ma brake drive ndi mapulogalamu omwe amafunikira DI/DO yowonjezerapo kuposa kulumikizana kwa PROFINET, chingwe cha I/O chiyenera kugwiritsidwa ntchito.

Kulumikizana kwagalimoto

SIMOTICS S - 1FL6 low - inertia motors (SH20, SH30, SH40) amagwiritsa ntchito chingwe - zolumikizira zamtundu.

Kulumikizana kwa chingwe cha brake komwe kukuwonetsedwa ndi kwa V90 400V pagalimoto yokha.
