FX2N-1RM-E-SET Programmable Cam Switch Introduction 1

1. Introduction
This section describes the outline of the programmable cam switch FX2N-1RM and introduces
the peripheral equipment.
1.1 Outline of the product
The programmable cam switch FX2N-1RM (hereinafter referred to as FX2N-1RM or unit) detects
the rotation angle of a machine using a brushless resolver, and turns on/off up to 48 points of
transistor outputs at a programmed angle (position).
The basic function of the FX2N-1RM is equivalent to a mechanical cam switch shown in the figure
on the next page. However, different from a mechanical cam switch, fine adjustment of the angle
of many cam discs assembled in the mechanism and replacement of switches are not required in
the FX2N-1RM.
1.2 Features
1 ) The angle can be detected with high precision even while a machine is rotating at high
speed.
2 ) One FX2N-1RM unit can be used individually or up to three FX2N-1RM units can be
connected at the end of the system and used as special units of an FX2N/FX2NC
programmable controller (hereinafter referred to as PLC).
(Refer to Paragraph 1.5 for details.)
3 ) When transistor output extension blocks for the FX2N are connected, up to 48 points of non-
contact outputs are available. Up to 32 points can be turned on at one time. Up to 8 ON/OFF
operations (STEP0 to STEP7) are enabled at each point.
(Maximum speed: 830 r/min during direct output)
4 ) Operation angle setting and monitor display can be performed from the dedicated data
setting panel (integrated add-on type) or by FROM/TO instructions given by the PLC main
unit.
5 ) An EEPROM (no battery) is built in. Up to 8 types of programs can be saved.
6 ) A bank can be changed over, a program can be modified, and the automatic angle advance
quantity can be modified while the program is running.
7 ) The ladder support software for personal computers in the PLC and the FX-20P-E (both of
them are compatible with FX2N) can be used to save or transfer programs.
8 ) The cable of the brushless resolver assembled in the machine can be extended up to 100 m
(3937 inch). (A relay cable of 5 m (196.85 inch) is offered as standard.)
9 ) The automatic angle advance function can compensate for the mechanical delay generated
while a machine is rotating at a high speed.

1.5 System configuration
1.5.1 Connecting the FX2N-1RM to PLC
• The output extension blocks which can be connected are limited to the transistor or triac type
of the FX2N series.
• Up to 3 FX2N-1RM units can be connected to the PLC main unit at the end of the system.
The number of blocks that can be connected depends on the PLC main unit and version of
the FX2N-1RM.
• The FX2N-1RM units occupy 8 I/O points without regard to the number of units connected.
(The ratio of input points and output points is arbitrary.)
• As shown in the diagram up to 48 points offered by output extension blocks can be
connected to the FX2N-1RM unit at the end of the system.
The extension blocks dedicated to outputs connected are treated as the outputs of the FX2N-
1RM. They are not recognized by the PLC main unit, and not included in the number of I/O
points (256 points maximum) of the FX2N PLC.
• Octal numbers are assigned as output Nos. of the extension blocks connected to the FX2N-
1RM from the extension block nearest to the FX2N-1RM (Y00 to Y07, U10 to Y17, . . . Y50 to
Y57).
• Only output extension blocks are allowed to be connected to the FX2N-1RM.
(Even if extension blocks dedicated to input are connected, no input can be received and
input Nos. are not assigned.)

FX2N-1RM-E-SET Programmable Cam Switch
• Each data or bit information can be read and written between the PLC main unit and the
FX2N-1RM using FROM/TO instructions.
When two or more FX2N-1RM units are connected, data information and bit information can
be read and written in only the FX2N-1RM unit nearest to the PLC main unit using FROM/TO
instructions directly given by the PLC main unit.
In the second and third FX2N-1RM units, data information and bit information are read and
written from the PLC main unit via the unit nearest to the PLC main unit.
• All the FX2N-1RM units must be installed adjacent to each other.

1.5.2 Using the FX2N-1RM individually
• The output extension blocks which can be connected are limited to the transistor type or triac
type of the FX2N series.
• Up to 48 output points can be connected to the FX2N-1RM. Octal numbers are assigned as
output Nos. from the extension block nearest to the FX2N-1RM (Y00 to Y07, Y10 to Y17, . . .
Y50 to Y57).
• Only extension blocks with dedicated output are allowed to be connected to the FX2N-1RM.
(If extension blocks with dedicated input are connected, no input can be received and input
Nos. are not assigned.)
• Two or more FX2N-1RM cannot connected without connecting the PLC main unit.

1.5.3 CC-Link connection
<Using the FX2N-1RM individually>
Composition
Flow data
• The communication between FX2N-1RM and FX2N-32CCL is always done while energizing
the power supply. The communication between FX2N-32CCL and master unit is done to the
link scanning.
• When setting the number of occupied stations of FX2N-32CCL is 1, BFM#9 of FX2N-1RM
(rotational speed) is not transmitted.
Set the number of occupied stations in 2 when you transmit the rotational speed.
• When cc-link is connected, setting and the program for the communication are unnecessary
in FX2N-1RM. Refer to each user’s manual for setting the communication in FX2N-32CCL and
