System compatibility

Compatibility description: ECN113 belongs to HEIDENHAIN ECN series absolute encoder family, EnDat01 interface. Compatible with HEIDENHAIN CC series control units and Fives Giddings & Lewis PIC900 CNC heavy boring mill spindle axis.

Function

Function description: ECN113 is absolute rotary encoder manufactured by HEIDENHAIN. Integrated stator coupling removes need for separate flexible coupling and minimizes mechanical backlash. It outputs absolute angular position data over EnDat bus immediately after power-up without reference homing. Robust aluminum housing protects optical components from vibration, coolant mist and metal chips. It is high precision spindle position measuring spare for heavy CNC boring mills.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off encoder DC power. Install encoder onto hollow spindle shaft and secure clamping of stator coupling. Connect shielded EnDat encoder cable to servo control unit. Restore power, verify LED indicators, run encoder diagnostic and test spindle orientation.

Interface

Interface list: Multi-core molded cable connector, DC power and EnDat signal terminals,on-board POWER / COM / FAULT LED indicators for HEIDENHAIN ECN113 2048 01-58.

Diagnostic

Troubleshooting: No encoder communication: Check DC supply voltage, cable breakage or connector pin damage. FAULT LED lit: EnDat communication timeout, low signal amplitude, over-temperature or shaft misalignment. Spindle orientation error: Shaft runout, coupling slip or contamination on optical grating.
