3D1 When the tool axis direction handle feed or tool axis perpendicular
direction handle feed function is used, the coordinates of the first rotation
axis are:
0: The machine coordinates when the tool axis direction handle feed
mode or tool axis perpendicular direction handle feed mode is
entered, or upon reset.
1: The value set in parameter No. 7144.
3D2 When the tool axis direction handle feed or tool axis perpendicular
direction handle feed function is used, the coordinates of the second
rotation axis are:
0: The machine coordinates when the tool axis direction handle feed
mode or tool axis perpendicular direction handle feed mode is
entered, or upon a reset.
1: The value set in parameter No. 7145.

When using the tool axis direction handle feed or tool axis perpendicular
direction handle feed function, define the rotation axes for the three basic
axes X, Y, and Z in the basic coordinate system as axes A, B, and C,
respectively, and the Z–axis represents the tool axis direction when the
rotation axes are positioned to the machine zero point. Then, depending
on the axis configuration of the machine, all four of the following types
are available. When a 4–axis machine and the tool axis perpendicular
direction handle feed function is used, only types (1) and (2) are available.
(1) A–C axis type
(2) B–C axis type
(3) A–B axis (A–axis master) type
(4) A–B axis (B–axis master) type
This parameter selects a type, values of 1 to 4 are assigned to these types.
When the X–axis represents the tool axis direction, the above types are
changed to B–A axis type, C–A axis type, B–C axis (B–axis master) type,
and B–C axis (C–axis master) type respectively.
