Boundary conditions

If in MD32074 $MA_FRAME_OR_CORRPOS_NOTALLOWED bit 10=0 and in NC program

ROT Z45 is programmed, then no axis replacement is possible for the X axis and the Y axis.

Similarly this applies to the Z axis, for instance with ROT X45 or ROT Y45 and also during

JOG mode, when a block with such programming is interrupted. In this case, however, the

signals for the X axis and the Y axis are at the VDI interface

IS DB31, ...DBX68.5 ("Replacement possible") = 1

IS DB32, ...DBX68.5 ("Replacement possible") = 1,

but both signals are reset to 0.

Only when in MD32074 $MA_FRAME_OR_CORRPOS_NOTALLOWED bit 10=1 and no

block currently interpolates with this programming, can a replacement for these axes be

done in JOG mode.

Axis replacement from synchronized actions

An axis can be requested with GET(axis) and be released for axis replacement with

RELEASE(axis) with a synchronous action.

The axis must be assigned as a channel axis via machine data.

An axis can be transferred directly between channels to a certain channel with the NC

language command AXTOCHAN via synchronized actions or in the part program. This axis

does not have to be the same channel and it is not necessary that this channel be in

possession of the current interpolation right for the axis.
