PLC iyo Mabaadi'da Xakamaynta Darawalka Stepper
Mabda'a Xakamaynta
Matoorada Stepper ayaa inta badan loo isticmaalaa meelaynta xakamaynta. Waxaa lagu xakameyn karaa tirada garaaca wadnaha ee ay soo saarto PLC si loo go'aamiyo xagasha wareega (iyo masaafada), iyadoo inta jeer ee garaaca garaaca uu nidaaminayo xawaaraha mootada. Nidaamyada mootada Stepper waa sahlan yihiin, kharash - wax ku ool ah, oo sahlan in la xakameeyo, taasoo ka dhigaysa inay ku habboon yihiin codsiyada halka saxnaanta xakamaynta aysan ahayn mid aad muhiim u ah. Xaaladaha xakamaynta saxda ah ee sare, nidaamyada xakamaynta servo ayaa caadi ahaan loo baahan yahay.
Habka stepper-ku waxa uu ka kooban yahay darawalka jaranjarada iyo matoorka tallaabo qaadka. Matoorka stepper-ka waxaa wata darawalka stepper-ka, kaas oo u shaqeeya sidii ilo koronto. Dareewalka waxa gacanta ku haya garaaca dibadeed iyo calaamadaha jihada (tusaale ahaan, garaaca wadnaha ee Siemens PLC), si loo habeeyo xagasha wareegtada iyo xawaaraha mootada.
Qeexitaanno Muhiim ah
1. Darawal:Dhexdhexaadiyaha u dhexeeya PLC iyo motor stepper. Waxay xoojisaa calaamadaha garaaca wadnaha ee PLC waxayna u gudbisaa matoorka jaranjarada, taasoo awood u siinaya matoorku inuu ku shaqeeyo si waafaqsan cabbirada ay dejiyeen PLC iyo darawalka.
2. Xagasha tilaabada:Xagasha uu matoorka stepper-ku ku wareego garaac kasta. Xagasha tilaabada guud waa 1.8°, kaas oo aan caadiyan la hagaajin karin.
Tusaale: Immisa garaac ayaa PLC u baahan tahay in ay soo saarto si ay ugu wareejiso matoor jaranjaro leh xagal tallabo ah oo ah 1.8° iyada oo loo marayo hal kacaan oo buuxa (360°) iyada oo aan wax yar laga qaadin?
Jawaab: 360° / X = 1.8° / 1 ⇒ X = 200 garaac.
3. Microstepping:Codsiyada wax ku oolka ah, xagasha tillaabada weyn waxay sababi kartaa gariir weyn waxayna kordhisaa khaladaadka xakamaynta. Microstepping-ku wuxuu u qaybiyaa xagasha tillaabada qaybo yaryar iyadoo la isticmaalayo dareemada DIP ee darawalka, taasoo keentay hawl qabad fudud.
Tusaale: Haddii xagasha tilaabadu tahay 1.8° oo microstepping loo dhigay 10, imisa garaac ayaa loo baahan yahay si uu u dhamaystiro hal kacaan oo buuxa?
Jawaab: 360° / X = (1.8° / 10) / 1 ⇒ X = 2000 garaac.
Soo koobid: Xagasha tilaabada weyn waxay u baahan tahay garaacyo yar, halka xagal yar yar uu u baahan yahay garaacyo badan.
Qalabka Nidaamka Stepper (Isticmaalka Phidgets Stepper Motor tusaale ahaan)
1. Darawalka Stepper
Xakamaynta garaaca + jihada: Marka garaaca wadnaha uu ka soo baxo PUL, matoorku wuu wareegayaa, iyadoo jihada ay go'aamisay DIR.
Kordhinta garaaca garaaca + Xakamaynta garaaca gadaasha: Pulses at PUL waxay ka dhigaan matoorku inuu hore u wareego, halka garaaca garaaca DIR uu ka dhigo mid rogan. PUL iyo DIR waa in aanay isku mar dhalin garaac.
2. Stepper Motor
Marka dabaylaha wejiga A iyo B la isweydaarsado, matoorku wuxuu u wareegayaa jihada ka soo horjeeda.
Voltage signal of stepper motor waa 5 V, halka Siemens PLC ka shaqeeya 24 V. A 1.2 K, 1/4 W resistor waa in si taxane ah loo xidho marka la isku xidho darawalka, sida ka muuqata qaybta cas ee jaantuska.
Siemens PLC (CPU222) waxay taageertaa laba nooc oo wax soo saarka garaaca garaaca sare ee xawaaraha:
PTO (Wax soo saarka tareenka garaaca): 50% wareegga shaqada.
PWM (Pulse - Hababka Balaadhka): Wareegga shaqada ee la hagaajin karo.
Wax-soo-saarka garaaca wadnaha-xawaaraha sare-sare waxaa loo isticmaali karaa in lagu xakameeyo darawalka stepper iyo dhaqdhaqaaqa iyo xawaaraha qalabka gaarka ah.
