System compatibility
401-57268-20 belongs to DANAHER MOTION Giddings & Lewis servo cable series. Matched with HD series servo motors and PiC900 / uDSM servo drive system. Widely applied on heavy boring mills, vertical turning centers and large horizontal machining centers.
Function
401-57268-20 is pre-terminated shielded encoder feedback cable manufactured by DANAHER MOTION Giddings & Lewis. It transmits low-voltage differential quadrature encoder position signals from motor built-in encoder back to control system. Twisted pair and full copper shielding prevent signal distortion caused by electromagnetic noise from power cables. Pre-finished connectors reduce wiring error and accelerate on-site maintenance replacement.
Installation
Follow lockout/tagout safety procedure before installation. Ensure all power of CNC cabinet and servo motor is fully cut off. Route 401-57268-20 cable inside drag chain, keep physical separation from servo power cable. Connect one connector to motor encoder port and the other end to control rack feedback terminal. Implement 360° shield grounding at cabinet side. Run continuity and insulation test before power-on.
Interface
Motor encoder side connector, control rack / drive feedback connector, continuous copper braid shielding for DANAHER MOTION 401-57268-20.
Feature
Original DANAHER MOTION 401-57268-20 encoder feedback cable assembly,low capacitance twisted pair,full copper braid shielding,oil & coolant resistant PUR jacket,factory pre-terminated connectors,UL & CE certified. This spare unit is used for Giddings & Lewis CNC machine servo axis encoder feedback wiring replacement.
Diagnostic
No encoder position reading: Check cable continuity, pin damage or loose connector mating. Intermittent position skip: Inspect cable fatigue in drag chain, shield continuity and grounding. Encoder noise alarm: Verify shield termination and separation from high-current servo power wiring.
