Technical Specifications

Model： 511398-01

Brand： HEIDENHAIN

Product Type: Prefabricated multi-core shielded encoder signal cable assembly

Module Feature:

Function: HEIDENHAIN 511398-01 ready-made shielded encoder cable. It supplies DC power and transmits sine/cosine incremental or EnDat absolute position signals between HEIDENHAIN encoders and interpolation / servo controller units. Full copper braid shielding suppresses electromagnetic interference, maintaining stable high-resolution position transmission for closed-loop axis control on heavy horizontal boring mills and large machining centers.

Cable type: Multi-core shielded PUR signal cable Matched Device: HEIDENHAIN rotary encoders and linear read heads with M23 interface Onboard components: Tinned copper conductors, PE insulation, full copper braid shielding, molded M23 connectors at both ends, integrated strain relief

LED indicators: Not applicable (Cable assembly)

Hardware self-diagnosis: Continuity test, insulation resistance test, shield continuity inspection

Programming software: No programming required

System compatibility

Compatibility description: 511398-01 belongs to HEIDENHAIN encoder accessory family. Compatible with HEIDENHAIN incremental and absolute encoders equipped with M23 connectors. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill system.

Function

Function description: 511398-01 is prefabricated shielded encoder cable manufactured by HEIDENHAIN. It connects linear or rotary encoder to interpolation unit or CNC servo control board, delivering DC power and position feedback signals. Copper braid shielding protects weak measuring signals from high-power servo motor electromagnetic noise. PUR outer jacket resists cutting fluid, oil mist and metal chips in machine workshop environment. It is encoder feedback wiring spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off encoder and CNC controller power. Disconnect old cable connectors at encoder and control end. Route 511398-01 separately from high-current servo power cables. Secure cable clamps and connectors. Check insulation resistance and shield grounding. Restore power, verify encoder communication and axis position stability.

Interface

Interface list: M23 flange connectors on both ends, power and signal terminals for HEIDENHAIN 511398-01.

Diagnostic

Troubleshooting: No encoder signal: Check power supply, internal wire breakage or connector pin damage. Intermittent position fault: Poor shield grounding, connector corrosion or cable insulation aging. Signal amplitude drop: Excessive bending damage to internal conductors or shield fracture.
