感情(kannjou) is used more commonly in everyday language. 情動(joudou) is more of a psychological term meaning "sudden emotional changes such as joy, hatred, anger, or fear that may trigger changes in one's physical conditions". I am not sure if you are translating a technical document or not. I hope my explanation will help.

It's Ayako again. I am making another submission just to make a correction. When I typed in "kanjou" in my previous submission, I had one extra "n" that you do not need. Oops, sorry!
