Boxford 160 TCL -Lenze 534 DC motor Driver Board

[JohnnyK]

Does anyone have experience repairing these Driver modules. The information avail online from Lenze and Boxford is (mushroom)
My spin (Chuck motor) did not start spinning when I turned machine on after a long period of non use. I have diagnosed problem to 534 driver board.

I have found a blown Rifa (Kermet) 150nF (0.15uF) 275V mains capacitor. This is mounted across a isolated power transformer which supplies 12volt and 3.5 volts to a daughter card mounted on edge of controller board. I can accept that old age and moisture would cause paper capacitor to fail especially when there is little margin for spikes in original 275V AC rated capacitor. I have ordered a higher rated new polyester capacitor that will fit but there may be other problems with the board. I am going to check and clean motor brushes today as it a good time to inspect brush lengths and clean commutator.

Does anyone have a full circuit diagram? --Or a working 534 module or board that they can sell me?
