Hello, I have a four axis specialized piece of equipment that is dead in the water. Whenever the servo drives are enabled, It blows the 35 amp fuses that feed the E/R modul Part number 6SN1145-1BA01-0BA2 INT 16/21 KW. The equipment was installed in 2012 and we had to search for the key to the electrical cabinet. The only documentation we have is operators manuals and a book of wiring diagrams that are still in German. The machine has an 840D control and a S7 PLC and a HMI interface. I isolated the DC buss from all loads, so I have a green LED but no DC buss voltage. when the drives are enabled, the green led goes out.We have no spare parts in house so I am trying to determine the minimum amount of parts to buy to get this machine running.
