19689 Retraction direction for the second rotary axis
[Data type] Byte
[Valid data range] 0 ~ 1
Set the direction in which the second rotation axis rotates as a mechanical motion
when a positive move command is issued.
0: Clockwise direction as viewed from the negative to positive direction of the axis
specified in parameter No. 19687 (right-hand thread rotation)
1: Counterclockwise direction as viewed from the negative to positive direction of
the axis specified in parameter No. 19687 (left-hand thread rotation)
Normally, 0 is set for a tool rotation axis, and 1 is set for a table rotation axis.
19690 Rotation angle when the second rotary axis is a hypothetical axis
[Data type] 2 Word
[Unit of data]
increment system IS-B IS-C Unit
Data unit 0.001 0.0001 deg
[Valid data range] -99999999 ~ +99999999
When the second rotation axis is a hypothetical axis (bit 1 (IA2) of parameter
No.19696 is 1), set the rotation angle.
#7 #6 #5 #4 #3 #2 #1 #0
19696 IA2 IA1
[Data type] Bit
# 0 IA1
0: The first rotation axis is an ordinary rotation axis.
1: The first rotation axis is a hypothetical axis.
If IA1 is 1, set 0 as the controlled-axis number for the first rotation axis (parameter
No. 19681).
Also, set parameter No.19682 to 19685 on the assumption that there is a rotation
axis.
# 1 IA2
0: The second rotation axis is an ordinary rotation axis.
1: The second rotation axis is a hypothetical axis.
If IA2 is 1, set 0 as the controlled-axis number for the second rotation axis (parameter
No. 19686).
Also, set parameter No. 19687 to 19690 on the assumption that there is a rotation
axis.
