什麼是 FUSA ? - Functional Safety

Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner (fail-safe). The automatic protection system should be designed to properly handle likely human errors, hardware failures and operational/environmental stress.

功能安全（Functional Safety）也稱為機能安全，是指和一個系統或是設備整體安全的組成部份^[1] 。其達成安全性的方式是靠系統或組成零件在接受輸入訊號後，可以正常的動作^[2]。例如一個馬達中加裝溫度感測器，若溫度超過一定值，即停止馬達運轉，此機能就屬於功能安全。
