Giddings & Lewis 502-03638-60 CPU Processor Module

Technical SpecificationsModel：502-03638-60 Brand：Giddings & Lewis Product Type: Single-slot plug-in PiC900 series main CPU processor module for PiC900 rack backplane

Module Feature:Function: PiC900 CNC core processor board, performs G-code interpretation, multi-axis motion trajectory interpolation, PLC logic execution, I/O module scheduling and system alarm management for heavy horizontal boring mills and large machining centers. Processor: High-speed real-time industrial processor Memory: Onboard flash firmware storage; battery-backed RAM for part programs, work offsets and machine parameters Bus: High-speed parallel backplane bus to communicate with I/O, encoder and SERCOS interface cards Hardware watchdog: Watchdog timer for system crash protection LED indicators: OK, RUN, FAULT diagnostic status lights Hardware self-diagnosis: Memory integrity test, backplane bus verification, watchdog timeout detection, power rail monitoring Programming software: PiCPro for firmware download, CNC parameter configuration, part program management and module diagnostic testing

Electrical ParametersBackplane supply:+5V from PiC900 rack backplane Power consumption:Max 4.9W Onboard lithium backup battery for memory retention during power loss

Mechanical & Structure:Mounting:Plug into PiC900 rack single slot Weight:0.24kg Protection class:IP20

Environmental:Operating temperature:0℃ ~ +60℃ Ambient humidity:5~85% non-condensing Certification:CE Status:Manufacturer discontinued legacy CNC CPU module

System compatibility502-03638-60 belongs to Giddings & Lewis PiC900 control platform. Compatible with PiC900 backplane, SERCOS fiber communication cards, digital / analog I/O modules and encoder interface boards. Widely fitted on G&L 70A horizontal boring mills and PMC CNC boring machines.

Function502-03638-60 is PiC900 main CPU processor module manufactured by Giddings & Lewis. It acts as the core computing unit of PiC900 CNC system. It decodes G-code, calculates multi-axis motion trajectories, executes PLC logic programs and exchanges data with all rack peripheral modules via backplane bus. The onboard backup battery preserves CNC parameters, offsets and part programs when main power is cut off. It is critical main controller spare for legacy heavy G&L CNC machine tools.

InstallationFollow lockout/tagout safety procedure before installation. Cut off rack backplane power. Insert 502-03638-60 module into PiC900 backplane slot and lock retainer. Inspect backup battery condition before power-up. Download machine parameters and part programs by PiCPro. Power on rack and run module self-test, then verify axis motion and I/O functions.

InterfacePiC900 backplane gold-edge connector,on-board OK / RUN / FAULT LED indicators for Giddings & Lewis 502-03638-60.

DiagnosticCPU boot failure:Check +5V backplane power, module seating or depleted backup battery. FAULT LED lit:Watchdog timeout, memory corruption or backplane bus communication error. No axis commands sent:Missing or incorrectly configured SERCOS communication card, wrong CNC parameters.

Product Brief502-03638-60 is Giddings & Lewis legacy PiC900 main CPU processor module,with battery-backed memory for G-code interpretation and multi-axis motion calculation on heavy CNC boring mills,discontinued CNC CPU spare card.
