Flex Pendant frozen on "Connecting to Controller"

I am in the process of commissioning an ABB 4600 and the pendant screen is frozen on "Connecting to Robot Controller" when the robot is powered on. I have tried with different flex pendants but it still gets stuck on that.

Is there a way to do a hard reset on the controller without the flex pendant? Or is there a way to do an I-start to get into the boot menu with out the flex pendant?

Thank you!


  • An older post on this forum describing the same issue indicates that holding the stop button and programmable key 1 together while booting should reload the image on the FlexPendant (if you have a hold-to-run button hold that too). If that doesn't work, I would contact ABB as the image may be corrupted.
