Good afternoon! Please tell me, the E.DRI error periodically pops up on our frequency converter during the operation of the shredder. What have we not done, but so far it is not possible to eliminate it. Please tell me what to do and how to defeat it, so that it does not arise anymore.KEB F5 160kW 2/4P 50/60Hz. ser.№ 300773793/1160991. power 208 KVA. Output 0...1600HZ. Immediately apologizing for throwing off one comment under all the videos, just otherwise it will pass by. And if you still find it necessary to answer, answer the last video. Thanks.
