3.2 AXIS INFORMATION
3.2.1 Reading the Actual Machine Position of Controlled Axes
Add "Reading the Actual Machine Position of Controlled Axes" to "5.5 AXIS INFORMATION".
[Description]
You can read the machine position (coordinates) using this function.
The position is read in the machine unit, independently of input unit.
When you set 1 to the data number, you can read the machine position
that servo delay and acceleration/deceleration delay is applied.
[Input data structure]

+6 (Data number)
N
(N=Data type)
0: Machine position taht servo delay and
acceleration/deceleration delay is not applied.
1: Machine position taht servo delay and
acceleration/deceleration delay is applied.
+8 (Data attribute)
M
(M=Axis number)
1 to n (n is the number of axes in the CNC-path) :
Reads the value of a specified axis.
-1: Reads the value of all axes in the CNC-path.
+10 (Data)
-
(Need not to be set)
CAUTION
The position is read in the machine unit,
independently of input system.
Therefore, the read value differs from the position on
CNC screen when displaying machine coordinates on
the ACTUAL POSITION screen with input system
(CNC parameter No.3104#0=1) on a machine that
has difference unit of input and output system.
