The use of the compressor function with active orientation transformation is described in:

3.5.2 Combining short spline blocks (option for 828D)
Function
During the processing of splines short blocks can so occur, that the path velocity for the interpolation of these
spline blocks must be reduced. This is alao the case, when the spline actually has a long, smooth curve.
The "Combine short spline blocks" function allows you to combine these spline blocks such that the resulting
block length is sufficient and does not reduce the path velocity.
Activation
The function "overview of short spline blocks" can be activated for following cases independent of each other:
• BSPLINE active
• BSPLINE/ORICURVE active
• CSPLINE active
The activation is done using machine data:
MD20488 $MC_SPLINE_MODE (setting for spline interpolation).
Note
NC block compressor
The NC block compressor (COMPON, COMPCURV or COMPCAD) cannot be employed
while compressing spline blocks since it can only be used to compress linear blocks.
Bit Value Meaning
Function "Combining shorter spline blocks":
0 0 for BSPLINE not active
1 for BSPLINE active
1 0 for BSPLINE/ORICURVE not active
1 for BSPLINE/ORICURVE active
2 0 for CSPLINE not active
1 for CSPLINE active
