Attribute
R: This data register can be used only for read. You should not write it.
R/W: This data register can be used both for write and read. When reading or writing data,
use a 16-bit instruction for a data register classified as "S", or a 32-bit instruction for a
data register classified as "D".
*1 In simultaneous 2-axis mode (available only in the FX
2N
-20GM), the special D for the X axis
is valid and the special D for the Y axis is ignored.
*2 In simultaneous 2-axis mode (available only in the FX
2N
-20GM), the same data is saved in
the special D for the X axis and the special D for the Y axis.
*3 Not defined in the FX
2N
-10GM.
Special data registers for current position data
Special data registers "D9005 and D9004" and "D9015 and D9014" shown in the previous
page store the current position data based on the practical unit set in PARA. 3.
You can write numeric data to these data registers while the positioning unit is ready (in the
AUTO or MANU mode) and is not waiting for remaining distance drive. When writing data, use
32-bit instructions.
On the other hand, special data registers "D9075 and D9074" and "D9095 and D9094" indi-
cating the current position converted into pulses can be used only for read, and their data auto-
matically changes in accordance with changes in the data stored in data registers "D9005 and
D9004" and "D9015 and D9014".
