1. Tsis sau thaum lub sijhawm ua haujlwm tsis siv neeg
Thaum lub dhia ua txoj haujlwm tau qhib thaum lub sijhawm ua haujlwm tsis siv neeg, xyuas qhov qis dua photoelectricity thiab txoj haujlwm ntawm photoelectricity - thaum lub nkoj dhia tau qis rau qhov chaw qis dua, txav mus rau qhov qis dua photoelectricity kom ntseeg tau tias qhov ntsuas qis dua qhov photoelectricity yog. Yog tias qhov ntsuas hluav taws xob qhov ntsuas hluav taws xob tsis tuaj yeem ua rau lub ntsej muag, nws yog qhov yuav tsum tau kuaj xyuas seb qhov hluav taws xob photoelectric ntsig txog qhov qis ntawm qhov dej ntws mus rau qis dua qhov qub. Yog hais tias lub Circuit Court ib txwm ua, nws txhais tau tias tus kws yees duab tau raug puas ntsoog, thiab nws yuav tsum tau hloov.
2. Lub cav servo tsis ua haujlwm
Tshawb xyuas seb puas muaj ib qho hniav txhawm rau hauv kev siv synchronous siv ntawm lub servo motor sab; Kuaj xyuas seb puas muaj cov ntsia hlau txhuas sab saud lub taub servo lub cev yog qhov txawv txav. Saib seb tus tsav tsheb servo puas muaj lub suab tsis meej. Thaum lub suab ceeb toom ntawm servo tsav tsheb cuam tshuam nrog qhov encoder, xyuas seb kab puas txuas txuas servo tsav mus rau lub encoder yog xoob lossis poob tawm. Yog tias cov kab zoo li qub thiab lub suab ntsig cuam tshuam ntawm lub servo tsav tsheb tsis tau raug tshem tawm, nws txhais tau tias kev kho vajtse tsis ua haujlwm (xws li encoder txhaum, servo tsav interface puas, thiab lwm yam).
