The axis control cards, CPU card, or motherboard (main CPU board) may be defective.
You may have to swap/replace any of: the axis control cards, CPU card, or motherboard (main CPU board).
It is ok to dismantle the motherboard with worry to erase the machine data and parameters. Is there instruction on how to replace the motherboard and axis card. Thankx
I have also problem with 921 alarm. Do you have instructio on how to replace motherboard and Axis Card. ThankxQuote:
