Introduction

TheFX-1PG/FX

2N

-1PG pulse generator unit (hereinafter referred to as “PGU”) performs simple positioning of an

independent axis (not interpolation control between multiple axes) by supplying a prescribed quantity of pulses (100 kHz
maximum) to drive amplifiers for servo or stepper motors.

•

The FX-1PG is attached as an extension to the FX/FX

2C

series programmable controller (hereinafter referred to as “PC”),

and theFX

2N

-1PG is attached as an extension to the FX

2N

series PC. Each PGU functions as a special block which

transfers data with thePC using theFROM/TO instructions, and occupies 8 points of inputs or outputs. Up to 8 PGU
units can be connected to single PC so operation for independent 8 axes can be realized.

•

The PGU provides connection terminals for positioning operations that require high-velocity responses as well as those
used for pulse train outputs. Other general I/O operations are controlled via the PC.

•

Because all the program for positioning control are executed in the PC, the PGU does not require dedicated teaching
panel, etc.  As theprogramming tools for thePC, thefollowing devices areavailablewithout modification.

➀

FX-10P-E and FX-20P-E

➁

General-purpose personal computer (IBM)

•

Various data access units as follows can be connected to the PC to set or display the positioning data.

➀

FX-10DU-E and FX-20DU-E
