HEIDENHAIN LC483 Linear Scale

Technical Specifications

Model： LC483, ID.Nr.680 600-01

Brand： HEIDENHAIN

Product Type: Sealed incremental linear encoder for machine tool feed axis

Module Feature:

Function: HEIDENHAIN LC483 sealed linear encoder. It detects linear travel position and speed of machine feed axis, outputs 1Vpp sine/cosine incremental analog signals to interpolation unit for high resolution position calculation. The aluminum extrusion housing with wiper seals protects internal glass grating tape. Used on heavy horizontal boring mills and large gantry machining centers for closed-loop axis positioning.

System compatibility

Compatibility description: LC483 belongs to HEIDENHAIN LC series linear encoder family, 1Vpp sinusoidal output. Compatible with HEIDENHAIN EXE interpolation units and Fives Giddings & Lewis PIC900 CNC system for heavy boring mill feed axis.

Function

Function description: LC483 is sealed incremental linear encoder manufactured by HEIDENHAIN. The enclosed aluminum profile and wiper blades block metal chips, cutting coolant and oil mist to protect the glass scale. The read head scans the grating and generates sine/cosine analog signals for position measurement. Reference mark is required for axis homing after power-up. It is high precision linear position measuring spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off encoder 5VDC power. Mount scale rail parallel to machine travel axis. Install read head on slide carriage, adjust air gap and parallelism. Connect shielded encoder cable to HEIDENHAIN EXE interpolation unit. Restore power, verify POWER and SIG LED indicators, run encoder diagnostic and test axis positioning.

Interface

Interface list: M23 multi-pin flange connector, 5VDC power terminal,on-board POWER / SIG / FAULT LED indicators for HEIDENHAIN LC483 680 600-01.

Diagnostic

Troubleshooting: No position reading: Check 5VDC supply voltage, cable breakage or connector pin damage. FAULT LED lit: Low signal amplitude, contaminated scale surface or read head misalignment. Intermittent position jump: Coolant ingress, wiper damage or optical component aging.
