Mechanical tsis ua hauj lwm, tswj cov teeb meem, thiab lwm yam yog vim li cas.
1. Mechanical Cheebtsam xws li cov kabmob puas thiab cov iav hnav tuaj yeem ua haujlwm tsis zoo, ua rau cov actuator co lossis nres ua haujlwm.
2. Circuit board faults, tsis ruaj tsis khov fais fab mov, thiab lwm yam tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub hollow rotating actuator.
3. Kev cuam tshuam ib puag ncig: Sab nraud ib puag ncig xws li kev co thiab kev hloov pauv kub kuj tuaj yeem ua rau lub hollow rotating actuator co los yog nres.
