System compatibility502-04104-10 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 backplane, PiC900 CPU boards and Centurion servo drives. Widely installed on G&L 70A horizontal boring mills and PMC CNC boring machines for X/Y/Z axis encoder feedback acquisition.

Function502-04104-10 is PiC900 encoder feedback module manufactured by Giddings & Lewis. It captures A/B/Z phase differential encoder signals from machine axes and performs pulse counting and position calculation. It feeds real-time axis position data to the CNC controller to complete closed-loop position control. Galvanic isolation suppresses electrical noise interference from machine power cabinet. It is critical spare position feedback board for legacy heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert 502-04104-10 module into PiC900 backplane slot and lock retainer. Connect shielded differential encoder cables to terminal connectors. Set encoder resolution and axis count direction parameters in PiCPro software. Power rack on and verify encoder reading and axis homing function.
