Hy there, I have DC Drive of ABB, model DCS-800. Field Card is making issues constantly giving error F537 M1FexRdyLost. I have checked it in Manual and use all my resources to clear it but all in vain. I am thinking about an idea to bypass the field card...instead of useing field card, we qill give field supply direct to field while using protection. Is there way to bypass the field vard from ABB DCS800 ?
