System compatibility

Compatibility description: 502-03809-02 belongs to Giddings & Lewis NumeriPath analog control family. Compatible with matching rack backplane, executive CPU and analog servo amplifiers. Widely fitted on vintage heavy G&L horizontal boring mills.

Function

Function description: 502-03809-02 is analog output board manufactured by Giddings & Lewis. It receives digital motion instruction data from CNC main processor, converts digital values into ±10V analog velocity signals via onboard D/A converter, and sends analog command signals to analog servo drives to control axis speed and position. It provides analog motion command output for legacy analog servo CNC systems. It is legacy analog output spare for old heavy G&L CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off rack +5V and ±15VDC power supply. Insert 502-03809-02 board into rack slot and secure gold finger connector. Wire analog command cables with shielded twisted pair. Complete channel calibration via CNC software, run self-test and verify analog command output and axis movement.

Interface

Interface list: Backplane gold finger connector, multi-channel analog screw terminal block,on-board POWER / ACT / FAULT LED indicators for Giddings & Lewis 502-03809-02.

Diagnostic

Troubleshooting: No analog output:Check ±15V reference supply, wiring or damaged D/A channel. FAULT LED lit:D/A conversion error, backplane communication failure or output short circuit. Drifting analog signal:Ground loop interference, poor shielding or reference voltage drift.
