Default value:
By setting the relevant NC MD bit, entries and modifications through the NC operator panel
can be prevented with the keyswitch.

Bit 7 Bit 7=0 F62 programming not active.
Default setting: 0
Bit 6
Bit 1 Bit 1=0 Cylindrical interpolation with 2 axes
Cylindrical interpolation can be activated for up to four axes, cylindrical interpolation remains
active. One limitation of this function is that the cylindrical interpolation axis must be
programmed as the 1st or 2nd axis in a block. The axes cannot therefore be programmed in
any order, nor can a circle be programmed without including the cylindrical interpolation axis. If
more than five axes are programmed in a block or if an axis other than the 1st or 2nd axis is
programmed as the cylindrical interpolation axis, alarm 2059 is output.
Default value:
Bit 0 Bit 0=0 Automatic generation of G68 for initial programming of rotary axes.
With this MD the user can define how the control is to behave on initial programming of the
axis by programming G68, G90 or G91. On a block search, the automatic generation of G68 is
retained because the user cannot influence by programming.
