Explanation
Swivel mode: Evaluation of swivel angle and swivel sequence (bit-coded)
Bit: 7 6
0 0: Swivel angle by axis -> see parameters _A, _B, _C
0 1: Solid angle -> see parameters _A, _B
1 0: Projection angle -> see parameters _A, _B _C
1 1: Direct rotary axis swivel mode -> see parameters _A, _B
Bit: 5 4 3 2 1 0 (these do not apply to solid angles)
x x x x 0 1 1st rotation _A around X
x x x x 1 0 1. rotation _A around Y
x x x x 1 1 1st rotation _A around Z
x x 0 1 x x 2nd rotation _B around X
x x 1 0 x x 2nd rotation _B around Y
x x 1 1 x x 2nd rotation _B around Z
0 1 x x x x 3rd rotation _C around X
1 0 x x x x 3rd rotation _C around Y
1 1 x x x x 3rd rotation _C around Z
Reference point X prior to rotation
Reference point Y prior to rotation
Reference point Z prior to rotation
1. Rotation acc. to setting in _MODE parameter
2. Rotation acc. to setting in _MODE parameter
3. Rotation acc. to setting in _MODE parameter
Reference point X after rotation
Reference point Y after rotation
Reference point Z after rotation
Initiate travel of rotary axes (default = -1!):
-1 = Position at smaller value of rotary axis 1 or 2
+1 = Position at larger value of rotary axis 1 or 2
0 = Do not swivel (merely calculate swivel frame)
Value (inc) of retraction in tool direction incremental
Display mode
UNITS: Machining plane G17/G18/G19
0 = Compatibility, the level effective before cycle call remains active
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
