HEIDENHAIN ECN413 2048 Absolute Rotary Encoder

Technical Specifications

Model：ECN413 2048 Brand：HEIDENHAIN Product Type: Bearing-integrated absolute rotary encoder with stator coupling

Module Feature

Function: HEIDENHAIN ECN413 2048 is an absolute rotary encoder with built-in bearing. It outputs EnDat01 absolute position data together with 1Vpp sine/cosine incremental signals,2048 incremental lines per revolution. It adopts 12mm hollow through shaft with clamping ring, matched with stator coupling to compensate installation misalignment. Cutoff frequency 400kHz, supports high speed rotation. Widely used on heavy horizontal boring mills, machining centers for spindle closed-loop position measurement.

System compatibility

Compatibility description: ECN413 series rotary encoder works with HEIDENHAIN EnDat controller and drives supporting 1Vpp signals. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill spindle axis.

Function

Function description: ECN413 2048 is absolute rotary encoder manufactured by HEIDENHAIN. It provides absolute angular position after power-on without full axis homing, meanwhile delivers high-quality 1Vpp sine/cosine incremental signals for high interpolation resolution. Hollow shaft design is convenient for spindle assembly. Stator coupling absorbs axial and radial mounting offset to protect internal bearing. Compact metal housing resists workshop vibration and temperature fluctuation. It is core measuring spare for heavy CNC boring mill spindle closed-loop control.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off all power supply. Fit encoder hollow shaft onto spindle, tighten clamping ring. Fix stator coupling to prevent housing rotation. Connect shielded EnDat encoder cable to control unit. Adjust mounting gap, lock all fasteners. Restore power, run EnDat communication test and signal amplitude verification.

Interface

Interface list: EnDat signal cable / connector, 3.6~14VDC power and measuring signal terminals, no LED indicators on ECN413 2048.

Diagnostic

Troubleshooting: No EnDat communication: Check power supply, cable breakage and connector contact. Weak incremental signal: Optical window contamination or shaft misalignment. Intermittent position loss: Loose clamping ring, bearing wear or cable abrasion.
