    Heidenhain TNC 426 CF

    I have a Heidenhain TNC 426 CF CNC machine. It is giving the error below:

    HEIDENHAIN OPERATING SYSTEM-FATAL ERROR MESSAGE
    SUN JAN 10 07:00:11 2021
    EXCEPTION-TASK NOT INSTALLED
    PC=004CC052

    Any ideas on how to solve this problem?

    Kindly assist

    Hi

    This might be a problem with your hard disk- there is a process for installing and re-initializing the hard disk for the TNC426 available in their service manual (available on the heidenhain website)

    You would need a new 2.5gb IDE Hard disk (SSD works better in my opinion) and after reinstalling the TNC system you can reload your parameter and PLC backups

    Best regards

    Hello everyone, I have a problem, the machine's hd stopped working, when I installed an 8gb ssd, it shows the message of the photo attached.
