DDPIDX
[Data type] Bit type
DDP Selection of decimal–point input method of index table indexing axis
0 : Conventional method (Example IS–B: B1; = 0.001 deg)
1 : Pocket calculator method (Example IS–B: B1; = 1.000 deg)
REL Relative position display of index table indexing axis
0 : Not rounded by 360 degrees
1 : Rounded by 360 degrees
ABS Displaying absolute coordinate value of index table indexing axis
0 : Not rounded by 360 degrees
The index table indexing axis rotates 720 degrees (two rotations)
when G90 B720.0; is specified from the 0–degree position. It rotates
in reverse direction 720 degrees (two rotations) when G90 B0.; is
specified. The absolute coordinate value then becomes 0 degree.
1 : Rounded by 360 degrees
The index table indexing axis is positioned in 40 degrees when G90
B400.0; is specified from the 0–degree position. The index table
indexing axis does not rotate by two or more turns when this
parameter is set to 1. It also does not move when G90 B720.0; is
specified from the 0–degree position.
INC Rotation in the G90 mode when negative–direction rotation command M
code (parameter No.5511) is not set
0 : Not set to the shorter way around the circumference
1 : Set to the shorter way around the circumference (Set ABS, #2 of
parameter No.5500, to 1.)
G90 Index table indexing command
0 : Judged to be an absolute/increment command according to the
G90/G91 mode
1 : Judged to be an absolute command
SIM When the same block includes a command for an index table indexing
axis and a command for another controlled axis:
0 : A P/S alarm (No.136) is issued.
1 : The commands are executed. (In a block other than G00, G28, and
G30, however, a P/S alarm (No.136) is issued.)
IDX Index table indexing sequence
0 : Type A
1 : Type B
5511
Negative–direction rotation command M code
[Data type] Byte
[Valid data range] 0 to 255
0 : Not use an M code that sets the index table rotation to the negative
direction. The rotation direction is specified using a command and
parameter (INC, #3 of parameter No.5500).
