Hello, I need some help.
My name is Tom Brooks, Greenwood, Indiana . I have a Fanuc A06B-6055-H218 that I am having trouble repairing. It was turned over to me after a local repair house did not have any luck. Where I am at now, I have changed out all IGBT's and other bad components including some on the top board. We had a regen problem. The drive would run fine but would not regen to a stop.
What I am unsure of is internal wiring from the SCR's to the 2 internal braking resistors.
At this point I am afraid to power up and run and stop a motor under a load without confirming the wiring.
Would you happen to have an internal layout of this drive and be willing to help us out? Any help here would be greatly appreciated.
Thank you ,
