Read data of the machine kinematics
1 QS parameter
no. Read the axis names of the active 3-axis
kinematics. The axis names are written
according to QS(IDX), QS(IDX+1), and
QS(IDX+2).
0 = Operation successful
2 0 Is FACING HEAD POS function active?
1 = Yes, 0 = No
4 Rotary axis Read whether the defined rotary axis partici-
pates in the kinematic calculation.
1 = Yes, 0 = No
(A rotary axis can be excluded from the
kinematics calculating using M138.)
Index: 4, 5, 6 ( A, B, C )
10 Axis Determine programmable axes. Determine
the axis ID associated with the specified axis
index (index from CfgAxis/axisList).
Index: 1 - 9 ( X, Y, Z, A, B, C, U, V, W )

11 Axis ID Determine programmable axes. Determine
the index of the axis (X = 1, Y = 2, ...) for the
specified axis ID
Index: Axis ID (index from CfgAxis/axisList)
