The following NC machine data still have to be set before you can operate the
drives after drive installation. You will find them by pressing the Diagnosis/Start-
up/Machine data/NC MD softkeys for the Axes (FDD) or Spindles (MSD) and
then Basic MD softkey.
Note
In the case of digital drives you should first enter the drive configuration before
the axis/spindle assignment.
