This appears to be a Fanuc CNC controller, about a model 10 vintage.
The first photo shows the servo controller, this recieves a position command from the CNC control and which bases the command on an encoder fed back to the control to indicate the actual position of the machine, and moves the servo's accordingly.
The main CNC controller PCB has typically co-processors for operating the CNC/servo/part program side, and also a processor for general machine I/O operations such as tool changers, coolant etc.
The spindle controller, obviously for the spindle motor, can also have encoder feed back to the control for operation such as tapping and helical milling. The controller synchronizes the servo's to the spindle rpm.
The main PCB is the 'Heart' of the system and coordinates the above functions and provides the operator interface and display.
