1. Introduction
This section describes the outline of the programmable cam switch FX
2N
-1RM and introduces
the peripheral equipment.
1.1 Outline of the product
The programmable cam switch FX
2N
-1RM (hereinafter referred to as FX
2N
-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 FX
2N
-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 FX
2N
-1RM.
1.2 Features
1 ) The angle can be detected with high precision even while a machine is rotating at high
speed.
2 ) One FX
2N
-1RM unit can be used individually or up to three FX
2N
-1RM units can be
connected at the end of the system and used as special units of an FX
2 N

programmable controller (hereinafter referred to as PLC).
(Refer to Paragraph 1.5 for details.)
3 ) When transistor output extension blocks for the FX
2N
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 FX
2N
) 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.
