System compatibility502-03944-00 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 CPU board, PiC900 backplane and SERCOS based Centurion servo drives. Widely used for G&L 70A horizontal boring mills and PMC series CNC boring machines.

Function502-03944-00 is PiC900 SERCOS fiber interface module manufactured by Giddings & Lewis. It handles high-speed real-time SERCOS fiber bus communication between CNC CPU and servo drives. Dual ring design improves network redundancy and reliability. It transmits cyclic motion commands and receives servo position feedback independently. RS232 port supports field firmware upgrade and module diagnosis. It is critical spare communication card for legacy G&L SERCOS CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert 502-03944-00 module into PiC900 backplane slot and lock retainer. Connect plastic SERCOS fiber cables to SMA ports and configure ring topology. Set SERCOS node addresses in PiCPro software. Power rack on and verify fiber link and servo slave communication.

InterfacePiC900 backplane gold-edge connector,dual SMA fiber ports,RS232 update port,on-board OK / RUN / COM / FAULT / RING LED indicators for Giddings & Lewis 502-03944-00.

DiagnosticServo slave offline:Check fiber cable, SMA connector cleanliness, ring termination or node address error. RING alarm:Fiber damage, broken ring or optical power attenuation. FAULT LED lit:Backplane communication fault or module firmware corruption.
