Note
If the following transfer parameters are programmed indirectly (as parameters), the input
mask is not reset: _FR, _ST, _TC, _MODE, _DIR
1) Can be selected when function is set up in IBN SWIVEL
2) Can be selected if direction reference to rotary axis 1 or 2 is set in IBN SWIVEL
If direction reference is "no" there is no selection field
3) Swivel selection "no" can be grayed out SD 55221 Bit 0
Swivel "no", "minus" direction corresponds to _DIR = 0 and _ST TEN THOUSANDS = 1
Swivel "no", "plus" direction corresponds to _DIR = 0 and _ST TEN THOUSANDS = 2
4) The direction selection for rotary axis 1 or 2 also occurs if the rotary axis with the direction
reference is in the pole position (position value equals zero).
5) Coding example: Axis-by-axis rotation, rotary sequence ZYX
Binary: 00011011 Decimal: 27
The axis identifiers XYZ correspond to the geometry axes of the NC channel. Individual
rotations around the XYZ axes are permissible. Example: rotary sequence around ZXZ is not
permitted in one call of CYCLE800.
