(PR) #7917 SLCT_G53_6_ROTAX
Specify in which order to rotate the rotary axes when the address Q is unspecified in G53.6 and when the
number of simultaneous contour control axes is limited to 4.
0: In the order of primary and secondary rotary axes
1: In the order of secondary and primary rotary axes
#7918 SLCT_ROTAX_ANS
[M8]
Select the solution that defines the calculated angle of the primary rotary axis when address P is omitted from
G53.1 or G53.6 command.
0: Default solution of each machine type
1: Solution that makes the primary rotary axis value positive
2: Solution that makes the primary rotary axis value negative
(PR) #7920 SLCT_T1
Select in which axis direction to rotate the tool rotating type base-side rotary axis.
If the tool axis is inclined, use the second digit to set the axis direction in which the tool axis is inclined.
0: Invalid
1: I axis rotation
2: J axis rotation
3: K axis rotation
(Note) 0 to 99 can be set from the screen, but if an invalid value is set, the operation error (M01 0127) will
occur when the power supply is turned ON.
---Setting range---
0 to 3
12, 13, 21, 23, 31, 32
(PR) #7921 TIANGT1
Set the inclination angle if the tool-rotation type base-side rotary axis is inclined. Set the angle regarding
CCW direction of the inclined plane as plus direction.
---Setting range---
-359.999 to 359.999 (°)
(Follow as "#1003 iunit Input setup unit".)
(PR) #7922 ROTAXT1
Set the name of the tool rotating type base-side rotary axis.
---Setting range---
A,B,C,U,V,W,X,Y,Z
2-digit of A to Z and 1 to 9
0: Mechanical axis specifications
#7923 DIR_T1
[M8]
Set the rotation direction of the tool rotating type base-side rotary axis.
The rotation direction specifications vary according to the setting of "#1450 5axis_Spec/bit3" (Select specifi-
cations of rotation direction parameter).
- When "#1450 5axis_Spec/bit3" = "0"
The specifications vary for each function.
- When "#1450 5axis_Spec/bit3" = "1"
The specifications are common to the functions.
0: When the tool motion viewed from the workpiece is in right-hand screw direction, it is taken as the pos-
itive direction.
1: When the tool motion viewed from the workpiece is in left-hand screw direction, it is taken as the positive
direction.
