Okuma lathe LB-25, OSP500L-G. Faulty drive unit BL-D 50A, SVP board power supply (inverter) part is dead.
1. Is it possible to find electrical diagrams of this SVP board?
SVP is a part of drive unit itself, it is the top board with "intelect"
2. Is it possible to purchase (could be used) SVP board or drive unit BL-D?
