• A compact, space-saving new type of DC reactor is built
into 200 V class 11 to 45 kW and 400 V 18.5 to 75 kW
models.
In addition to reducing harmonics, this reactor limits the
input current to 110% of the rated output current, and it has
been designed to be compatible with power supply systems
containing transformers, molded-case circuit breakers, and
power lines.
Adding on the optional DC reactor enables compliance with
IEC harmonics standards.
• High-frequency noise is drastically reduced on models with
built-in noise filters. Built-in noise filters are ideal for sites
from commercial facilities and offices through to factories
where attention must be paid to peripheral devices.
Compared with filter not integrated models, space and
wiring savings have been achieved by incorporating the
filter in the panel. Also, models with built-in EMC noise
filter comply with the European EMC Directive as
individual inverter units.

For machinery that requires simple function
This makes the inverter ideal for drilling machines, handling machines,
conveyors, semiconductor production equipment, cutting machines, and
woodworking machinery that require simple function.

• In the Quick mode, pressing the EASY key on the panel allows
EASY key
you to operate the inverter by eight basic parameters.
When setting each of the functions, press the EASY key to move
to the standard mode by one-touch operation. In this mode, you
can access all parameters.
• You can customize the Quick mode display, maximum of 32

Side-by-side installation
Side-by-side installation
• Side-by-side installation of inverters is possible up to the inverter's
total capacity. This allows effective utilization of space inside
control panels. Heat sink can be installed outside of the panel as
an option.
Removable control terminal board
• A removable terminal board is used. This allows you to use the
Removable control terminal board control wiring when replacing the inverter, which also makes
maintenance easier.
ON/OFF control of cooling fan
• Temperature-based ON/OFF control reduces noise while the inverter
is being stopped, saves energy and extends the cooling fan's life.
Monitoring of serviceable parts/alarm output
• The expected replacement cycle of main circuit capacitors,
capacitors on control board, and cooling fan is monitored, and an
alarm is output when the cycle is reached.
