System compatibility

Compatibility description: LIC4100 belongs to HEIDENHAIN LIC series exposed linear encoder family. Compatible with HEIDENHAIN CC series control units and third-party CNC systems. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill feed axis.

Function

Function description: LIC4100 is exposed absolute linear encoder manufactured by HEIDENHAIN. The non-enclosed grating strip design enables ultra-high accuracy and large measuring travel. The HSP1.0 ASIC improves tolerance to dust and minor contamination. Absolute position value is available immediately after power on, eliminating reference run and preventing axis collision on startup. Optional zero-expansion glass ceramic scale minimizes thermal drift. 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 DC power. Mount scale strip parallel to machine travel axis. Install scanning head on slide carriage, adjust scanning gap and parallelism. Connect shielded encoder cable to CNC or servo control unit. Restore power, verify LED indicators, run encoder signal test and axis positioning calibration.

Interface

Interface list: M12 or D-sub communication connector, DC power terminal,on-board POWER / COM / FAULT LED indicators for HEIDENHAIN LIC4100.

Diagnostic

Troubleshooting: No position reading: Check 3.6~14V supply voltage, cable breakage or connector pin damage. FAULT LED lit: Insufficient signal amplitude, contamination on grating, read head misalignment or hardware fault. Unstable position: Vibration, mounting parallelism error or grating surface contamination.
