FR-A800 Plus Series

Unparalleled Performance. Uncompromising Quality.

High performance and high quality new inverter of the highest level.
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.

  •  ● Speed response
    Real sensorless vector control
    50 Hz*1 (A700 : 20 Hz)
    Vector control
    130 Hz*2 (A700 : 50 Hz)
*1 : At 3.7 kW with no load Differs depending on the load conditions and motor capacity.
*2 : The option (FR-A8AP, FR-A8AL, or FR-A8TP) is required.

Example of the speed change when an impact load is applied


  •  ● Torque accuracy
  Real sensorless vector control Vector control
Torque control range 1:20 1:50
Absolute torque accuracy*3 ±20% ±10%*5
Repetitive torque accuracy*4 ±10% ±5%*5
*3 : Difference between the actual torque and the torque command
*4 : Fluctuation between the average of the actual torque and the actual measured torque (repeatability of the torque)
*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.)

CC-Link IE network

■ 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 parameters. The optimal inverter rating can be chosen in accordance with the application.
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.

Environmental adaptability

■ Global compatibility
UL, cUL, EC Directives (CE marking)
  •  ● Complies with UL, cUL, and EC Directives (CE marking), and the Radio Waves Act (South Korea) (KC marking). It is also certified as compliant with the Eurasian Conformity (EAC).
  •  ● Being RoHS compliant, the FR-A800-R2R series inverters are friendly to people and to the environment.
■ 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 resistance. ("-60" or "-06" is affixed to the end of the inverter model name.)
