    okay, we checked for the hidden parameters before we started the re-initializing process using the instructions on the Mazak Service Bulletin 0989-002 "How to re-initialize a T2\3 Control". There were no values on the hidden pages of ACT no.1 & ACT no.2

    We went through the RI process and made some headway. Hydraulics come on now, we try to send it home and it travels past limit and throws an alarm 1 servo lag excess or 14 servo lag excess.

    can anyone help me with this?
