ACS550-01-015A-4+B055 AC drives IGBT module blown
can anyone please assist with a service manula or circuit diagram for this unit.
i have 4 diodes blown close to the IGBT module, designators: V24, V26, V28, V31 as well as V22 and V22. i cannot see the part number code writtten on the diodes.
also parts numbers for opto isolator drivers H1, H2 and H3
probably the cost of spare parts and labor does not justify a repair. Furthermore the ACS550 series is production output, perhaps you should consider a new product of the ACS580 series in IP 55 version.
The diagrams of the drives are available only for ABB Service technicians, you can try to ask your ABB dealer to put you in contact with the Service, but on that type of drive they will surely tell you that the repair is not convenient.
