HEIDENHAIN ROD 1380 100 Incremental Rotary Encoder

Technical Specifications

Model：ROD 1380 100 Brand：HEIDENHAIN Product Type: Bearing-integrated incremental optical rotary encoder requiring external flexible shaft coupling

Module Feature

Function: HEIDENHAIN ROD 1380 100 is incremental rotary encoder with built-in precision bearing. It outputs 1Vpp sine/cosine A/B/Z incremental measuring signals, 100 lines per revolution. Solid shaft design, must connect with motor shaft by external flexible coupling to compensate axial and radial installation offset. Max scanning frequency 120kHz, supports medium spindle rotational speed. Widely used on heavy horizontal boring mills, machining centers for spindle angular position and speed closed-loop measurement.

Function

Function description: ROD 1380 100 is incremental rotary encoder manufactured by HEIDENHAIN. It generates high-quality sine/cosine incremental signals for electronic interpolation to achieve higher resolution. Reference mark Z pulse is used to establish machine datum after power cycle. External coupling isolates mechanical misalignment and protects encoder internal bearing. Compact metal housing withstands cutting oil, dust and vibration in machine workshop. It is precision measuring spare for heavy CNC boring mill spindle motion control.

Installation

Installation steps: Follow lockout/tagout safety procedure before installation. Cut off all power supply. Fix encoder synchro flange, mount flexible coupling between encoder solid shaft and machine spindle. Connect shielded encoder cable to interpolation or CNC control unit. Adjust coupling alignment, lock all fasteners. Restore power, run signal amplitude test and reference mark detection test.

Interface

Interface list: Signal connector, 5VDC power and 1Vpp measuring signal terminals, no LED indicators on ROD 1380 100.

Diagnostic

Troubleshooting: No measuring signal: Check 5V power supply, cable breakage or connector pin contact. Reference mark cannot be detected: Optical window contamination or coupling misalignment. Intermittent signal fluctuation: Vibration, coupling wear or bearing deterioration.
