Function
Function description: 1FK7042-5AF71-1EH2 is permanent magnet synchronous servo motor manufactured by HEIDENHAIN. Natural cooling structure reduces fan maintenance work. Built-in Drive-CLiQ absolute encoder can directly read absolute position after power on without axis homing. Compact structure and strong overload capability satisfy high dynamic positioning requirements for machine tool feed axis. It is high precision drive spare for heavy CNC boring mills.
Installation
Installation steps: Follow lockout/tagout safety procedure before installation. Cut off motor power. Mount servo motor through IMB5 flange, connect shaft with mechanical structure. Connect power cable and Drive-CLiQ encoder cable to lock the connector ring. Fix cable to avoid tensile stress. Restore power, run motor identification and positioning test.
Interface
Interface list: Rotatable power connector, Drive-CLiQ encoder connector for HEIDENHAIN 1FK7042-5AF71-1EH2,on-board POWER, COM, FAULT LED indicators.
Diagnostic
Troubleshooting: Motor no movement: Check drive enable signal, power cable and encoder connector. Intermittent positioning alarm: Cable abrasion, poor connector contact or mechanical stuck. Motor overheating: Long time overload, poor ventilation or bearing damage.
