[?]: Help in Simovert Source and Converters

Post by most » Mon Apr 28, 2008 8:52 am

I have a source Simovert 6SE7036-1EE85-1AA0 typ D380-450 G510-620 imput 3AC-380-480 output DC-510-620
and 2 converters Simovert VC 6SE7032-6TG60-Z and 2 VC 6SE7031-6TF60-Z for some many times an alarm F008 to activate all converters (F008 = DC link undervoltage, low tension in bus DC) and stopping the production.
I think that he is made a mistake, this defect appears because the source broken the output DC for high tension not low tension :!: (some times the line = 438 AC) and the converters detect low tension in the BUS.
DC source is regulated for imput 400 VAC. I can modify the tension in the source for 420 VAC to minimize this defect ? :?:
already I lowered the tension in the converters P071 of 500 for 470 V but I do not obtain success.
i can not modify the source of 400 AC for 420 AC because de P071 it is blocked (?) how enable this.
in option, how as I eliminate the function F008 in the converters so that they do not alarm by F008 :?:

many thanks for any help
