Fadal Circuit Boards

Fadal Circuit Boards

The Fadal circuit boards mainly consist of Power distribution boards and the CNC Rack containing all the circuit boards that control the CNC. The block diagram (below) shows the functional layout of the CNC Rack.

 

 

Care should be taken when handling circuit boards in order to prevent Electronic Discharge.   You should discharge yourself or wear an earth lead before handling boards, and avoid touching pins and contacts.
