The multi-tier limit-angle protection device includes a first-axis potentiometer for generating a first-axis sensing signal, a first-axis limit-angle detecting module for generating a first-axis confirming signal, and a controller. The controller effectuates a first tier protection mechanism by determining whether a limit angle of the rotation axis is exceeded according to the first-axis sensing signal, effectuates a second tier protection mechanism by determining whether the first-axis potentiometer is operating well according to a first-axis confirming signal, and effectuates a third tier protection mechanism through its control over the driving motor. The multi-tier limit-angle protection device features integration of software and hardware to thereby preclude mechanism complexity and provide a multi-tier limit-angle protection mechanism."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-tier limit-angle protection device","description":"A multi-tier limit-angle protection device detects a rotation angle about a rotation axis of a driving apparatus to thereby control the operation of a driving motor of the driving apparatus.
