Hello Dear Experts, we have 6ra70 drives for rolling mill application. one of drive tripped on F030 (its image attached herewith) here r949.01 =1, for same how to read manual ? wheather its mean "THE BLOCKING VOLTAGE TIME AREA FOR THE COMMUTATING THYRISTOR PAIR WAS TOO SMALL" or else ? and at fault time i have observed current was very low, so to resolve this problem which parameter need to change ? Thanks for your support, Meet.

Hello : PISCEAN 2010, Needs more information. 1. Is this permanent nature or sporadic type problem? This is once in while problem, in last three month 2 times occured. ( this time we have observed that fault occur when billet tail end pass from Stand) 2. Is it observed at particular speed or at any speed range? at any speed 3. Have you checked the field current? physicaly not checked, but according to trace field current dropped after fault (check attached trace file). 4. Is drive mechanic in good working condition? Mechanical system in good condition. ------------------------------------------------------------------------ one more query i have, pls check attached image for n735 or status word/control word parameter in drive monitor possible to view in decimal from binary / nibbal /hex ?

New question published by AhmaD_T is split to a separate thread with the subject F030 and fault value 1"The blocking voltage time area for the commutating thyristor pair was too small". Best regards |
