Best regards, Hristo Mihalev on command is taking there is no any alarm / fault suddnly it will 5Hz to 25Hz but there is no stabilize in frequency. I tryed to P0700 = 1 instead of 6 and P1000 = 1 instead of 6 even also its not stabilize in constsnt speed why..?

I was just woondering, as mentioned by you earlier, you checked by setting P700=1 and P1000=1 In such case I dont think P2000 is effective Are you sure you didnt changed anything else?
