    Try reflashing the TPU:


    From another ABB Forum:


    As you power up the controller you can try to hold stop button + programmable key 1 (hold the buttons down until you see red text indicating image missing or something similar then release them). If you have hold-to-run buttons at the bottom of the flexpendant you should hold one of these as well.

    This will reload the image on the TPU.

    If this doesnt help then you need to contact ABB to fix the flash disk on the controller which may be corrupt.
