Lub servo tsav board muaj kev tiv thaiv dab tsi? Xws li overload, overcurrent, overtemperature, thiab luv Circuit Court tiv thaiv?

Servo lub servo tsav lub rooj tsavxwm ua lub hauv paus tswj ib feem ntawm lub servo system, feem ntau integrates ntau yam kev tiv thaiv kev ua haujlwm kom muaj kev nyab xeeb ntawm lub cev muaj zog thiab kis tau tus mob nyob rau hauv kev ua haujlwm txawv txav. Kev tiv thaiv kev ua haujlwm ntawm servo tsav boards thiab lawv cov qauv kev ua haujlwm yog raws li hauv qab no:

I. Kev tiv thaiv overload
Cov lus piav qhia muaj nuj nqi: Thaum lub cev muaj zog load tshaj qhov ntsuas tus nqi, lub phaj tsav cia li txwv tsis pub tso zis hluav taws xob lossis ua rau kaw los ntawm kev saib xyuas tam sim no lossis lub zog tawm tswv yim los tiv thaiv lub cev los ntawm kev puas tsuaj los ntawm overload.
Txoj kev ua
Kev kuaj pom tam sim no: Teem 150% -200% ntawm cov ntsuas tam sim no kom dhau qhov pib. Tom qab qee lub sijhawm, kev tiv thaiv tau tshwm sim.
Dynamic torque txwv: Cov zis torque yog hloov kho nyob rau hauv lub sijhawm tiag tiag los ntawm algorithm los tiv thaiv lub cev muaj zog los ntawm kev poob vim yog overloading instantaneous.
Daim ntawv thov scenarios: Robotic caj npab grabs hnyav khoom, conveyor siv jammed, lwm yam load dheev nce scene.

3. Kev tiv thaiv overcurrent
Cov lus piav qhia muaj nuj nqi: Thaum lub cev muaj zog tam sim no tshaj qhov kev nyab xeeb (piv txwv li, luv luv Circuit Court lossis rotor xauv), lub rooj tsav xwm tsav tsheb yuav txiav tawm lub hwj chim tam sim ntawd los tiv thaiv cov cuab yeej hluav taws xob (xws li IGBT) los ntawm kev kub hnyiab vim overheating.
Txoj kev ua
Kho vajtse kaw nrawm: Tam sim no tau saib xyuas hauv lub sijhawm tiag tiag los ntawm lub ntsuas tam sim no. Thaum qhov kev txwv dhau lawm, lub hwj chim hloov tau muab tua hauv microseconds.
Software graded teb: Ua rau ceeb toom lossis kaw ntawm ntau theem nyob ntawm seb qhov tam sim no tshaj qhov txwv (xws li . 1.5 lossis 2 npaug ntawm qhov ntsuas tam sim no).
Daim ntawv thov scenarios: Sudden nce ntawm lub cev muaj zog pib torque thiab rotor xauv los ntawm kev sib tsoo tshuab.

4. Kev tiv thaiv overheat
Cov lus piav qhia muaj nuj nqi: Thaum qhov kub ntawm lub tshuab tsav los yog lub cev muaj zog tshaj qhov kev nyab xeeb, nws cia li ua haujlwm lossis kaw hauv lub peev xwm me dua los tiv thaiv kev puas tsuaj thermal.
Txoj kev ua
Kub sensor Saib xyuas: NTC thermistor lossis PT100 qhov ntsuas kub ntsuas tau teeb tsa hauv qhov tseem ceeb xws li tsav phaj fais fab module thiab lub cev muaj zog winding.
Dynamic derating tswj: lub zog tso zis yog maj mam txo thaum qhov kub thiab txias nyob ze ntawm qhov chaw pib thiab yuam kom kaw thaum qhov pib tshaj.
Daim ntawv thov scenarios: Kub kub ib puag ncig, ntev - lub sij hawm siab load ua hauj lwm tsis txaus tshav kub dissipation thiab lwm yam.

5. Kev tiv thaiv luv luv
Cov lus piav qhia muaj nuj nqi: Thaum lub cev muaj zog winding lossis tsav phaj tso tawm qhov kawg luv luv Circuit Court, yuav tsum tau txiav tawm sai sai, kom tsis txhob muaj kev puas tsuaj rau cov khoom siv.
Txoj kev ua
Hardware Short Circuit Detection: Los ntawm kev sib piv qhov ceev ntawm qhov poob qis lossis kev hloov pauv tam sim no, nws muaj peev xwm txheeb xyuas cov luv luv Circuit Court thiab hloov cov khoom siv hluav taws xob hauv nanoseconds.
Software Diagnostic Logic: Los ntawm cov qauv waveform tam sim no, peb tuaj yeem paub qhov txawv ntawm qhov pib tam sim no thiab luv luv - Circuit Court txhaum.
Daim ntawv thov scenarios: luv luv Circuit Court tshwm sim los ntawm puas lub cev muaj zog cables los yog tsis raug kev thaiv.

6. Kev tiv thaiv kev kub siab / overpressure
Cov lus piav qhia muaj nuj nqi: Thaum cov khoom siv hluav taws xob hluav taws xob qis qis lossis siab dua qhov ntsuas qhov ntsuas, lub phaj tsav tau kaw los yog kho hom kev ua haujlwm kom tsis txhob muaj qhov txawv txav ntawm lub cuab yeej.
Txoj kev ua
Voltage sampling piv: tiag -lub sij hawm saib xyuas ntawm DC tsheb npav voltage, tshaj qhov txwv thaum tiv thaiv.
Regenerative braking kev kho mob: Thaum muaj qhov overvoltage tshwm sim, lub zog ntau dhau yog siv los ntawm lub braking resistor kom tsis txhob muaj hluav taws xob nce ntxiv.
Daim ntawv thov scenarios: Voltage anomaly scenarios xws li hloov pauv ntawm daim phiaj hluav taws xob thiab lub zog tsis ruaj khov.
