System compatibility

Compatibility description: LIP101R belongs to HEIDENHAIN LIP series exposed linear encoder family, 1Vpp output. Compatible with HEIDENHAIN EXE interpolation units and Fives Giddings & Lewis PIC900 CNC system for heavy boring mill precision feed axis.

Function

Function description: LIP101R is exposed incremental linear encoder manufactured by HEIDENHAIN. The solid steel phase grating provides excellent rigidity and high measuring accuracy. The read head scans the grating and generates sine/cosine signals for position calculation. Reference mark is required for axis homing after power-up. It is widely used for ultra-precision machining tasks where high positioning repeatability is required. 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 steel scale bar parallel to machine travel axis. Install scanning head on slide carriage, adjust air gap and parallelism. Connect shielded M23 encoder cable to EXE interpolation unit. Restore power, verify POWER and SIG LED indicators, run encoder signal test and axis homing calibration.

Interface

Interface list: M23 multi-pin flange connector, 5VDC power and 1Vpp signal terminals,on-board POWER / SIG / FAULT LED indicators for HEIDENHAIN LIP101R.

Diagnostic

Troubleshooting: No position reading: Check 5VDC supply voltage, cable breakage or connector pin damage. FAULT LED lit: Low signal amplitude, grating contamination or read head misalignment. Intermittent position jump: Vibration, improper scanning gap or debris on grating surface.
