System compatibility

501-05055-00 belongs to DANAHER MOTION Giddings & Lewis legacy CNC rack family. Compatible with older Giddings & Lewis CPU board, servo axis control cards, encoder feedback boards and I/O modules. Widely used on heavy-duty boring mills, vertical turning centers and large horizontal machining centers.

Function

501-05055-00 is interface PCB board manufactured by DANAHER MOTION Giddings & Lewis. It works as signal conditioning bridge between CNC rack logic and machine field devices. It buffers digital and analog signals and suppresses transient surges and noise interference, protecting main processor and motion control cards from field circuit damage. On-board LEDs allow maintenance technicians to quickly judge board power and fault status.

Installation

Follow lockout/tagout safety procedure before installation. Fully power off CNC rack. Insert 501-05055-00 gold finger card into vacant rack slot and lock retention bracket. Wire field signal cables according to Giddings & Lewis hardware manual. After installation, power on and execute signal communication verification test.

Interface
