System compatibility

501-03203-01 belongs to DANAHER MOTION Giddings & Lewis legacy CNC rack family. Compatible with older Giddings & Lewis CPU board,encoder feedback cards and I/O interface boards. Widely used on heavy boring mills,vertical turning centers and large horizontal machining centers.

Function

501-03203-01 is four-axis analog servo control PCB board manufactured by DANAHER MOTION Giddings & Lewis. It receives digital position instructions from CNC main CPU,converts digital position data to analog velocity commands via high resolution DAC chip. The analog signals are sent to servo amplifiers to drive 4 independent machine axes. It also receives encoder feedback data to complete closed-loop positioning calculation. On-board LEDs help maintenance staff quickly verify each servo channel working state.

Installation

Follow lockout/tagout safety procedure before installation. Fully cut off CNC rack power supply. Insert 501-03203-01 gold finger card into empty rack slot and lock retention bracket. Wire analog command and encoder feedback cables following Giddings & Lewis hardware manual. Power on,perform axis calibration and multi-axis motion test after wiring.

Interface

Gold-edge backplane connector,analog servo signal terminal block,on-board status LED indicator for DANAHER MOTION 501-03203-01.

Feature

Original DANAHER MOTION 501-03203-01 4-axis analog servo control board,precision DAC analog command generation,built-in signal surge protection,gold finger rack plug-in design,LED channel diagnostic indicators,UL & CE certified.
