6. Checking the Warning Label on the Main Body
Check that warning label is attached on the main body.
If the label is missing or hard to read due to stain, contact our service department.
[Warning symbols on the nv series main body]
This symbol is a warning symbol for dangerous parts. It is attached on places
where there is a risk of an electric shock or a risk of damage to the main body due
to wrong wiring.
Note the following where this symbol is present.
●Touching the power input terminal of the power supply module while the power is on
causes an electric shock and is very dangerous.
Do not touch the power input terminal.
●For safety, turn off the power before wiring or performing maintenance and inspection.
●Wire the power input terminal correctly, and avoid applying any voltage exceeding the
specified voltage range. It may cause failure or damage.
●Perform connector connection of the nV-Tool port after turning off the power of the nV-Tool
(such as the PC).
Turn on the power of the nV-Tool after connection.
Be careful not to short-circuit the connector pins with the connector cover.
[Warning stickers]
The warning sticker as shown in the left
figure is attached to the power terminal
of the nv series (except for power
supplies below 24V).
Remove the sticker from the mount,
and attach it on the main body of the
nv series, or on a location near the nv
series where it can be seen easily.
There are stickers in both Japanese
and English. Use the one that suits
your need.

On Installing type1/type2
Controllers
Unified controller nv series have two types; type1 and type2.
The type1 controller is mainly used for high-speed sequence control as a successor of S
model of the integrated controller V series.
The type2 controller is mainly used for loop control as a successor of L model of the
integrated controller V series.

1.1 Functions and Characteristics of the Controller
Unified controller nv series inherit functions of the conventional integrated
controller V series and have the following features.
Computing performance has been improved by directly executing
IEC language by the hardware.
As it is designed to execute international standard language IEC 61131-3
instructions with ASIC directly on the hardware, you can set the execution time of
sequence instruction word to 20ns (1/2 compared to our product) at maximum
and the control cycle to 0.5ms at minimum.
High reliability has been achieved by the redundant structure of
modules and application of ECC circuit of the internal memory.
You can build a duplexed system having two sets of the power, CPU and
transmission modules. Furthermore, you can not only detect errors but also
correct them by applying ECC circuit to the internal memory of each module. The
complex circuit is highly integrated by ASIC to reduce the number of parts and
the failure rate.
It is equipped with the fastest serial I/O system “TC-net I/O” first
time in the industry.
The field I/O system that provides 100Mbps transmission rate and allows loop
duplexed structure has been achieved first time in the industry. You can collect
fast I/O data and set the minimum time of collection cycle to 100μs. The
transmission channel is normally duplexed loop (sending and receiving) structure
that can be further duplexed.
High reliability has been achieved by introducing Gigabit and
redundant supervisory control network.
The supervisory control network employs Ethernet whose transmission rate
is1Gbps and can further duplex the transmission channel. It allows you to use the
international standard Real-Time Ethernet “TC-net 100” as a network between
controllers. It is designed to be connected with conventional devices via a
switching hub and gateway.
