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.)

-20GM is displayed by LED.
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.

manner.
4.6 Connection with PLC
Refer to the FX
2N
-10GM and the FX
2N
-20GM HARDWARE PROGRAMMING MANUAL for details concerning
the system configuration.
The FX
2N
-GM-5EC cable is used to connect the FX
2N
-20GM to an FX
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
-
CNV-IF must be used. Eight blocks may be connected to an FX
2N
PLC and four blocks may be connected
to an FX
2NC
PLC.
