With MP10 you define which machine axes are to be operable.
The bits may be changed during the run-time without a control reset.
However, the bits to be changed must have been set before the control was
switched on.
Changing bits that had not been set leads to a control reset.
Note
Axis 9 may only be used as a PLC axis.
