System compatibility

401-57268-30 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

401-57268-30 is pre-terminated shielded encoder feedback cable manufactured by DANAHER MOTION Giddings & Lewis. It carries low-voltage differential quadrature encoder position signals from motor built-in encoder back to the control system. Twisted pair and full copper shielding prevent signal distortion caused by power cable electromagnetic noise. Pre-finished connectors reduce wiring error and speed up field maintenance replacement.

Installation

Follow lockout/tagout safety procedure before installation. Ensure all power of CNC cabinet and servo motor is fully cut off. Route 401-57268-30 cable inside drag chain, separate it physically 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.
