This manual only describes the specifications for FX

2N

-20GM positioning controller.

For complete operation, wiring, mounting and programming instructions please refer to the FX

2N

-10GM,

FX

2N

-20GM HARDWARE PROGRAMMING MANUAL, FX PROGRAMMING MANUAL and FX SERIES

HARDWARE MANUAL.
These manuals should be read and understood before attempting to install or use the unit.

1. Reference manual

Refer to the under mentioned manual for details about product installation, operation and programming. 

1) FX

2N

-10GM, FX

2N

-20GM HARDWARE PROGRAMMING MANUAL

The installation, wiring and the instructions of the FX

2N

-10GM and FX

2N

-20GM units are explained.

2) E-20TP OPERATION MANUAL

The operation of the input of the program which uses E-20TP and the monitor and the test is
explained. 

3) FX-PCS-KIT-GM-EE SOFTWARE MANUAL

The program is input via the FX-PCS-KIT-GM-EE. The manual explains the operation of the monitor
and test functions. 

The manual in 1) is not included with the product. Please request from the shop where the unit was
purchased if required. The manuals in 2) and 3) are included with the product.

2. Outline of the unit

The FX

2N

-20GM positioning controller (hereinafter call FX

2N

-20GM or 20GM) is a pulse chain output unit

that enables the positioning control of a stepping motor or a servo motor via the drive unit.

One  FX

2N

-20GM can control 2 axes. (Linear interpolation and circular interpolation are available.)

Both dedicated positioning language (cod instructions) and sequence language (basic instructions 
and application instructions) are available. 

A pulse generator can be connected to each axis or one pulse generator can be connected to both 
axes and switched as required. The manual pulse generators must be an open collector output type.

The zero return operation at each start can be omitted with a servo amplifier with the absolute position 
(ABS) detection function. 

The FX

2N

-20GM can be used alone. When an FX

2N

-20GM is connected with an FX

2N

 or FX

2NC

 

series Programmable controller (hereafter call PLC), reading and writing the positioning data can be 
done. (When FX

2N

-20GM is connected with the FX

2NC

 series PLC, an FX

2NC

-CNV-IF is necessary.)

Name of LED

Content

POWER

LED lights when power is supplied. If LED is not lit, check power supply voltage and 
current.

READY-X

LED lights when accepting an x-axis instruction. During pulse output or when an error 
occurs, the LED is off.

READY-Y

LED lights when accepting a y-axis drive instruction. During pulse output or when an 
error occurs, the LED is off.

ERROR-X

LED is lit or blinks when an error occurs in the positioning drive of x axis. 

ERROR-Y

LED is lit or blinks when an error occurs in the positioning drive of y axis. 

BATT

LED lights when the buttery voltage drops. (Turn Power Supply On)

CPU-E

CPU error. Incompatible system configuration, excess noise, etc.

4.3 I/O connector

The pin array of the I/O connector is as follows. 

All terminals with identical names are shorted internally (Ex. COM1-COM1, VIN-VIN, etc.).
Do not wire  “•” terminals.

2N

 PLC. When a long distance is

required, one FX

2N

-GM-65EC cable can be used per system. To connect to an FX

2NC

 PLC, the FX

2NC

Install the memory board in the connec-
tor.

4)

Replace the cover before turning on the
