INT Selection of the spindle to be clamped: (Only for call from Jobshop) (Call
of user cycle CUST_TECHCYC)
(Only for call from Jobshop) (At present
only 0 and 2 evaluated)
0 = Do not clamp spindle
1 = Only clamp spindle for vertical in‐
sertion with G00 or G01
2 = Clamp spindle during the entire
machining operation
Reserved
Position pattern with/without rotary axis –
axis combination
(with <_VARI> HUNDRED THOU‐
SANDS)
0 = XY (only XY without rotary axis,
compatibility)
1 = X,Y or Z and rotary axis:
XA, YB, ZC
(1 rotary axis with geometry axis
around which the rotary axis ro‐
tates)
2 = XY and rotary axis:
XYA, XYB, XYC
(1 rotary axis with 1st and 2nd
geometry axis, without TRACYL)
Rotary axis
0 = Without rotary axis
(only XY, compatibility)
1 = A axis (rotary axis around X)
2 = B axis (rotary axis around Y)
3 = C axis (rotary axis around Z)
Position pattern with rotary axis – offset
(for several rotary axes around the same
axis; if index too large, then 1st axis)
00 = 1st A, B or C axis or for compati‐
bility
01 = 2nd A, B or C axis
...
19 = 20th A, B or C axis
3 = Clamp/release main spindle
23 = Clamp/release counterspindle
