Features
Unparalleled Performance.
Uncompromising Quality.
High performance and high quality new inverter of the highest level.
1
With the enhanced drive performance and usability, the inverter is compliant with applicable safety standards.
Approach to the leading drive performance
Fast response
The improved speed response ensures a
minimal speed fluctuation to maintain a
constant speed when the load fluctuates.

*5: When online auto tuning (adaptive magnetic flux observer) enabled
System support
Compatibility to various open networks
A controller can control and monitor an inverter via network. As well as a standard
RS-485 interface, communication options are also available for the CC-Link IE
Field Network, DeviceNet™, and PROFIBUS-DPV0.
(Not compatible with the SSCNET III(/H) or FL remote communication.)
Human-machine
interface (HMI)
Environmental adaptability
Global compatibility
• The inverters are compatible with UL,
cUL, EC Directives (CE marking). This
product is also certified for compliance with the Eurasian Conformity (EAC).
(The Radio Waves Act (South Korea) (KC mark) will be supported soon.)

• Being RoHS compliant, the FR-A800-R2R series inverters are friendly to people
and to the environment.

Selection of optimum capacity
to suit the application
Five ratings of different rated current
and overload capacity (SLD rating
(super light duty), LD rating (light duty),
SND rating (super normal duty), ND
rating (normal duty), HD rating (heavy
duty)) can be selected with param-
eters. The optimal inverter rating can
be chosen in accordance with the ap-
plication.
If using an inverter with capacity of 75K
or higher, or motor with capacity of 75
kW or higher, always select and install
the inverter based on the capacity of
the motor with DC reactor.
Improved environmental resistance
[Measures against dust, dirt, and corrosion]
The inverters with PCB coating (IEC60721-
3-3 3C2/3S2) and conductive plating are
available for improved environmental resis-
tance. ("-60" or "-06" is affixed to the end of
the inverter model name.)
