Hello to all.

I have bought an used unpowered machine with fanuc 21i-m. The controller powers on, and some errors appear related to the battery power down (error nº 300). I have replaced the batterys and I am looking for a procedure to reset the axis to the correct position.

But before that I need to change the language of the controller. Currently it is in Spanish and I would like to have it in English. I must confess that I do not have experience with this controller, so be kind on explanations.

I have found the parameter to change languages, and when I try to replace the bit from 1 to 0 I receive a flashing error, that PROBABLY says in spanish protected. I have put PWE=1 before, so I really do not know what to do more.

Thank you
