System compatibility

Compatibility description: 1FK7 series servo motor matches HEIDENHAIN drive system. Suitable for Fives Giddings & Lewis PIC900 CNC heavy boring mill feed axis.

Function

Function description: 1FK7042-5AF71-1GH2 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. Integrated holding brake locks shaft when power loss to prevent axis sliding. 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, brake test and positioning test.

Interface

Interface list: Rotatable power connector, Drive-CLiQ encoder connector for HEIDENHAIN 1FK7042-5AF71-1GH2,on-board POWER, COM, FAULT LED indicators.

Diagnostic

Troubleshooting: Motor no movement: Check drive enable signal, power cable, encoder connector and brake release signal. Intermittent positioning alarm: Cable abrasion, poor connector contact or mechanical stuck. Motor overheating: Long time overload, poor ventilation or bearing damage. Brake failure: Brake coil damage, power supply fault, mechanical jamming.
