The FX
2N(C)
and FX
3U(C)
PLCs support connection with the FX
2N
-10PG special function block. As
described in section 4.3, special function blocks are separate pieces of hardware that can be con-
nected to a PLC to enhance control. Due to the separate processing sequence that takes place in spe-
cial function blocks through the use of buffer memory data, special function blocks provide a distinct
advantage to PLC programming through individualized control that expands and improves PLC oper-
ations. Additionally, special function blocks such as the FX
2N
-10PG include extra input points and out-
put points.
An important reference for understanding positioning with the FX
2N
-10PG is:

4.4.1 Overview of control
The FX
2N
-10PG is used to perform point-to-point positioning operations on 1 axis up to 1,000,000
pulses/second (1 MHz). With the FX
2N
-10PG differential line driver type outputs that provide
improved stability and better noise immunity, a stepper motor or servo motor can be controlled to
perform a variety of positioning operations including multi-speed positioning and interrupt stop
positioning. The controller also supports the connection of a manual pulse generator dial to control
individual pulses from a position dial. Another advantage to using the FX
2N
-10PG is the ability to use
a defined set of positioning operations in table format with up to 200 predefined table operations.
