3 Part Names and Functions
3-8
CP1E CPU Unit Hardware User’s Manual(W479)
Number
Name
Function
(1)
Input terminal block
This is the terminal block for inputs such as the power supply input and
24-VDC inputs.
(2)
Input indicators (yellow)
Input status is displayed. An indicator will be ON when the input is ON.
(3)
Peripheral USB port
Used to connect to a personal computer for programming and monitor-
ing by the CX-Programmer for CP1E.
(4)
Analog adjusters for
N/NA
-type CPU Units
By turning an analog adjuster, it is possible to adjust the value of A642
or A643 within a range of 0 to 255.
(5)
Operation indicators
The CPU Unit’s operating status can be confirmed with this indicator.
Refer to CPU Unit Status Indicators (Page 3-9).
(6)
Power supply input terminal Power of 100 to 240 VAC or 24 VDC can be supplied.
(7)
Input terminals
Input devices such as switches and sensors can be connected.
(8)
Ground terminal
Protective ground (
): To prevent electric shock, ground to 100
Ω
or
less.
Functional ground (
): If noise is a significant source of errors or if
electrical shock is a problem, connect to the protective ground terminal
and ground both with a ground of 100
Ω
or less (AC power supply only).
(9)
Expansion I/O Unit connec-
tor
CP-series Expansion I/O Units or Expansion Units such as Analog I/O
Units, and Temperature Sensors can be connected.
Refer to 5-2-4 Connecting Expansion I/O Units and Expansion Units.
(10)
Output indicators (yellow)
Output status is displayed. An indicator will be ON when the output is
ON.
(11)
Output terminal block
This is the terminal block for outputs such as relay outputs, transistor
outputs, and the external power supply output.
(12)
Output terminals
Loads such as lamps, contactors, and solenoid valves can be con-
nected.
(13)
External power supply ter-
minals
The external supply terminals output up to 300 mA max at 24 VDC.
They can be used as a service power supply for input devices (AC
power supply only).
(14)
Battery cover for
N/NA
(S
)-type CPU
Units
A Battery can be installed by opening the cover. (Battery is optional).
(15)
Built-in RS-232C communi-
cations status indicator
This indicator will be flashing when the built-in RS-232C port is in com-
munication mode.
(16)
Option Board slot for
N/NA
-type CPU Units
An Option Board can be connected to the slot.

mounted only to N30/40/60 or NA20 CPU Units version 1.2 or higher.)
(17)
Built-in RS-232C port for
N/NA
(S
)-type CPU
Units
By connecting a PT, the controlled system can be monitored and data
can be collected.
(18)
Built-in RS-485 communi-
cations status indicator
This indicator will be flashing when the built-in RS-485 port is in commu-
nication mode.
(19)
Built-in RS-485 port for
N
S1-type CPU Units
Communications are possible between an inverter and a PLC by using
Modbus-RTU and Serial PLC Links.
(20)
Analog input terminals for
NA
-type CPU Units
Analog output devices such as switches and sensors can be con-
nected.
(21)
Analog output terminals for
NA
-type CPU Units
Analog input device can be connected.
