Hello there,
I am trying to fix the problem of error message E-14 on J300 Frequency inverter, it says ground fault
on the output side, but even I disconnect the wires at the UVW on the inverter side it still shows the same message and once I reset it a new message appear as E-33.
I was thingking the problem is with the IGBT Module which has a part number 6MBP75JA120, 75A, 1200V, IT IS A SIX PACK IGBT's with built in drivers. How can I check it if it is working properly? It has a connection printed on it like P,N U,V,W. How can I test it like testing a brick type IGBT's thru a 12v battery & a lamp?
Thanks in advance to anybody that can help me with the above.
best regards to all,
CRR
