Specifically refers to one's sense of ethics or ethical values.
When discussing ethics in a general, abstract, or philosophical sense.
倫理 (ethics) often refers to social or professional standards, while 道徳 (morals) is more about personal or societal right and wrong. In many contexts they overlap, but 倫理 is the safer choice for 'ethics' as a concept.
倫理 is often combined with other nouns to specify the type of ethics, e.g., 医療倫理 (medical ethics), 企業倫理 (corporate ethics), 情報倫理 (information ethics). This is a very productive pattern.
彼は道徳に反する行為をした。
He acted against ethics/morals.
