HEIDENHAIN 344228-03 Encoder Cable Assembly

Technical Specifications

Model： 344228-03

Brand： HEIDENHAIN

Product Type: Prefabricated shielded encoder signal cable assembly for incremental encoders

Module Feature:

Function: HEIDENHAIN 344228-03 pre-assembled shielded encoder cable. It supplies 5VDC power and transmits sine/cosine incremental position signals between HEIDENHAIN rotary or linear encoders and interpolation electronics or CNC controller. Full copper braid shielding suppresses electromagnetic noise, ensures stable position data transmission for closed-loop axis control on heavy horizontal boring mills and large machining centers.

Cable type: Multi-core shielded signal cable Matched Device: HEIDENHAIN ROD, ERN series rotary encoders and LS/LB linear scales Onboard components: Tinned copper conductors, PE insulation, overall copper braid shield, molded M23 flange connectors, strain relief protection

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: 344228-03 belongs to HEIDENHAIN encoder accessory family. Compatible with HEIDENHAIN incremental encoders equipped with M23 interface. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill.

Function

Function description: 344228-03 is prefabricated shielded encoder cable manufactured by HEIDENHAIN. It connects linear or rotary encoder to EXE interpolation unit or CNC axis control board, delivering DC power and incremental sine/cosine feedback signals. Copper braid shielding isolates weak encoder signals from high-current servo power interference. PUR outer jacket withstands cutting coolant, oil mist and metal chips in 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 5VDC power. Disconnect old cable connectors at encoder and control side. Route 344228-03 separately from 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, 5VDC power and signal terminals for HEIDENHAIN 344228-03.

Diagnostic

Troubleshooting: No encoder signal: Check 5VDC 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.
