Safety measures
Operating environment
After installing the unit, make sure to use it within the range of the general
specifications:
 Ambient temperature: 0°C to +55°C
 Ambient humidity: 10%–95% RH (at 25°C, non-condensing)
 Pollution degree: 2
 Do not use the unit in the following environments:
 Direct sunlight
 Sudden temperature changes causing condensation
 Inflammable or corrosive gases
 Excessive airborne dust, metal particles or salts
 Benzine, paint thinner, alcohol or other organic solvents, or strong
alkaline solutions such as ammonia or caustic soda
 Vibration, shock, or direct drop of water
 Influence from power transmission lines, high voltage equipment,
power cables, power equipment, radio transmitters, or any other
equipment that would generate high switching surges. Maintain at
least 100mm of space between these devices and the unit.
Static electricity
Before touching the unit or equipment, always touch some grounded metal
to discharge any static electricity you may have generated (especially in
dry locations). The discharge of static electricity can damage parts and
equipment.
Protection of power supply
 Use a twisted power supply wire.
 Insulate the wiring systems to the CPU, input/output devices, and me-
chanical power apparatus.
 An insulated power supply with an internal protective circuit should be
used (FP power supply). The power supply for the CPU is a
non-insulated circuit, so if an incorrect voltage is directly applied, the
internal circuit may be damaged or destroyed.

6 FP7 Analog Output Unit User's Manual
 If using a power supply device without an internal protective circuit,
always make sure power is supplied to the unit through a protective
element such as a fuse.
 Be sure to supply power to a CPU and an expansion unit from the same
power supply, and turn the power on and off simultaneously for both.
Power supply sequence
Make sure the power supply of the CPU turns off before the power supply
for input and output. If the power supply for input and output is turned off
first, the CPU will detect the input fluctuations and may begin an unex-
pected operation.
Before turning on the power
When turning on the power for the first time, be sure to take the precau-
tions given below.
 During installation, check that there are no scraps of wiring, particularly
conductive fragments, adhering to the unit.
 Verify that the power supply wiring, I/O wiring, and power supply volt-
age are all correct.
 Sufficiently tighten the installation and terminal screws.
 Set the operation mode selector to PROG mode.
Request concerning program storage
To prevent the accidental loss of programs, the user should consider the
following measures:
 Backing up programs: To avoid accidentally losing programs, destroying
files, or overwriting the contents of a file, use the backup or export
functions of Control FPWIN Pro and store the files in a safe place. Addi-
tionally, you can print out the entire project documentation.
 Specifying passwords: The password setting is designed to avoid pro-
grams being accidentally overwritten. If the password is forgotten,
however, it will be impossible to overwrite the program even if you
want to. Also, if a password is forcibly bypassed, the program is delet-
ed. Therefore, please note the password in a safe location.

FP7 Analog Output Unit User's Manual 9
Chapter 1
Overview
1.1 Features
The analog output unit converts its internal data into analog values to be
output to inverters or other analog-driven devices.
 The unit is equipped with six types of output ranges (voltage ranges of
-10V to +10V, 0V to +10V, 0V to +5V, and +1V to +5V and current
ranges of 0mA to +20mA and +4mA to +20mA).
 The unit has 4 channels to output analog data.
 The conversion speed is 25μs/channel.
 Digital values are converted into analog data with up to 16 bits in a res-
olution range of 1/25000–1/62500.
Optional functions
Name
Description
Analog output
in PROG mode
Use this function to specify the operation of the analog output
when the PLC is switched from RUN to PROG mode: stop output,
hold the current value, or hold a user-defined value.
Offset/gain
processing
Offset and gain adjustment can be used to correct offset or scal-
ing errors. The offset and gain adjustments are made to the
converted data before it is written to the CPU's output area.
Scale conver-
sion
Use scale conversion to set an easy-to-use analog output range.
The digital input values are scaled to values in the specified
range between preset minimum and maximum values before
they are written to the CPU's output area.
Upper and
lower limit
clipping
In order to protect connected devices, this function limits the
analog output value by clipping the digital input value if it ex-
ceeds the specified upper or lower limit.

Overview
10 FP7 Analog Output Unit User's Manual
1.2 Basic operation
The processing of digital input data takes place in three steps:
1. Writing of digital data
A user program is needed to write the digital input values to the analog
unit into the CPU's output area (WY) on a channel-by-channel basis.
2. Digital to analog conversion
The digital input values are converted to analog output values automat-
ically and in sequence.
3. Analog signal output
Analog signals are output to inverters or other analog-driven equip-
ment.

Use double-core twisted-pair shielded wires.
Ground the shielding of the shielded wire on the load side. How-
ever, depending on the conditions of the external noise, it may
be better to ground the shielding externally or not to ground the
shielding.
Do not place the analog output wires close to power lines or load
lines other than PLC wires, and do not bundle them with other
wires.
The NC terminals of the output terminal block are unused. Do
not use these terminals to connect wires because some of the
terminals are connected internally.

I/O allocation
FP7 Analog Output Unit User's Manual 17
Chapter 3
I/O allocation
3.1 General
Each unit attached to the CPU must be configured in an I/O map which is
registered in the CPU. The current I/O map can be displayed in the "I/O
map and unit configuration" dialog. It shows the slot numbers and starting
word numbers of the CPU and its expansion units. I/O addresses are allo-
cated based on the starting word number.
To display the current I/O map and starting word number of a unit in Con-
trol FPWIN Pro, proceed as follows:
1. Open project
2. Double-click "PLC" in the navigator
3. Double-click "I/O map and unit configuration"
4. Double-click the desired slot number
Please refer to the CPU Hardware User's Manual for details on entering
and uploading I/O maps.
3.1.1 Digital values and control flags
Before D/A conversion, the digital input values to the analog unit are writ-
ten to the CPU's output area (WY). Control flags are also allocated to the
CPU's outputs.
The I/O addresses in the table show offset addresses. I/O addresses actu-
ally allocated are based on the first word number allocated to the unit.
Example: If the first word number is 10, the address number for the digital
input value on channel 0 will be WY10.
