FX Series Positioning Controllers
7.4 Positioning using the table method (FX
In the Single-axis positioning unit FX
so that positioning is enabled using the FROM/TO instructions of the PLC.
This function allows positioning control operations using peripheral equipment for the PLC
even when peripheral equipment dedicated to the positioning unit is not available.
(When the absolute position detection function is used, peripherals equipment for the position-
ing unit are necessary to change the parameter.)

Outline of the table function

When the special auxiliary relay M9165 of the FX
using the table method becomes valid.
A maximum of 100 table entries are provided. Each entry holds four types of information: com-
mand code (corresponding to the instruction), position data (address), speed data and m code
value. The information is saved in the general-purpose registers of the positioning unit. Two
data registers (32 bits) are used to save one piece of information.
The data register No. and the table entry No. (described later) are fixed. D1000 is assigned to
entry No. 0. (One hundred entries No. 0 to 99 are available.)
When the positioning data is written to the assigned data registers using the TO instruction and
operation is started, positioning is performed based on the written information.

Declaration of table method

To use the table method, the special auxiliary relay M9165 of the FX
ON.
M9165: Table method function valid (Buffer memory #30 b5)
Sequence program example (switches M9165 ON):
M8002
Once M9165 is turned ON, it remains ON until the power is turned OFF. Accordingly, once the
table method is declared, it remains valid until the power is turned OFF.
