controlled via the PLC.
In order that the operating software identifies the spindle as analog spindle, enter the axis
index of the analog spindle in the following machine data:
MD51068 $MNS_SPIND_DRIVELOAD_FROM_PLC1
MD51069 $MNS_SPIND_DRIVELOAD_FROM_PLC2

Instead of transferring the compensation data via the part program or INI file to the NC, you
can enter and check the compensation data for all axes or change the configuration in an
input screen.
Finally, the changed data is activated in the NC in one step. The machine data required
when activating is set automatically.
