Inverter - FREQROL
FR-A800 SERIES
What is required of inverters in this constantly changing world?
At Mitsubishi, we have pursued the answer to this question through constant innovation and evolution. Introducing our extensive range of high-value, next-generation inverters delivering outstanding drive performance in any environment, and a wealth of functionality covering startup to maintenance. We utilized the traditional Mitsubishi philosophy to further perfect our inverters.
The FR-A800 Series variable frequency drive is Mitsubishi Electric’s most advanced and capable VFD solution. Whether your needs call for a simple component style solution or large capacity motor control centers, the FR-A800 is designed to be flexible and offers a wealth of embedded functionality to simplify your application and implementation. Ideal for many simple tasks like fan and pump control, the FR-A800 also excels in performing more complex and demanding applications like multi-axis coordinated motion, load sharing conveyors, and gantry hoisting systems. Similar to other inverter products manufactured by Mitsubishi Electric, the 800 Series continues the tradition of maintenance free operation and long lasting service life. Mitsubishi Electric VFDs are world renowned for their high level of performance, efficiency and outstanding reliability – start using solutions that give you the competitive edge.
Key Benefits
Drives For Every Industry
High response speed
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.
Speed response: The speed response indicates how fast the inverter follows the change in the speed command. (The larger value indicates the better speed trackability.)
<Line control>
Line control is necessary for the machining of elongated products such as paper, thread, wires, all kinds of sheet, and tape. This will respond rapidly to changes in line speed and suppress the occurrences of winding unevenness.
This contributes to a steady supply of high-quality products.
Perform ultra-fine processing
V/F control 590 Hz*3 [A700: 400 Hz]
*3 : According to the review result of the export control order about frequency changers, the upper limit of output frequency was determined to be 590 Hz for standard models.
<Machine tool>
Cutting-edge machine tools are harder and thinner than ever before to be applicable to diverse new materials.
High-speed rotation is required more than ever before in order to be applicable for fine and precise cutting on hard and difficult-to-grind materials.
Swiftly move heavy weights-High torque at low speed
Real sensorless vector control 200% (ND rating)* 4, Vector control 200% (ND rating)* 4 (150% of initial setting for 5.5K and higher)
[Zero-speed torque]
Vector control 200%. (Select HD rating.)* 4
[Speed control range]
V/F control 1:10 (6 to 60 Hz: Driving)
Advanced magnetic flux vector control 1:120 (0.5 to 60 Hz: Driving)
Real sensorless vector control 1:200 (0.3 to 60 Hz: Driving)
Vector control 1:1500 (1 to 1500 r/min: Both driving/regeneration)
*4 : Please see the catalog for more details
<Crane>
Cranes are in operation daily at ports carrying fully-laden containers in response to strong demand from all over the world. Our new inverter realizes smooth cargo handling work at low speed and high torque for the slow and stable movements required for heavy objects.

·
*3 : Available for the 5.5K or higher.
·
*4 : For using the 75K or higher inverter
and a 75 kW or higher motor, always install a DC reactor (FR-HEL), which is
available as an option.
·
*5 : Always install the converter unit
(FR-CC2). (Not required when a high power factor converter (FR-HC2) is used.)
Compliance with EU EMC Directive with inverter alone
Troublesome acquisition of standards is
unnecessary.
· The FR-A800 series is equipped with an EMC filter as standard
for compliance with EMC Directive with the inverter alone. (EN 61800-3 2nd
Environment Category C3)
· The newly developed drive technology and the power supply technology minimize the EMI emitted from inverters.

Global compatibility
Compliance with a variety of standards
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 series inverters are friendly to people and to the
environment.
· For the 400 V class*1, compliance with various countries ship classifications allows use on ship equipment. (A noise filter is required for the FR-A840 inverter and the FR-CC2 converter unit, and a ferrite core is required for the FR-A846 inverter. (Refer to page 175).)

Protected in hazardous environment
Circuit board coating
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.)
Wire saving, space saving
Built-in brake transistor
In addition to the 22K and lower, 400 V class
30 to 55K models have also been equipped with a built-in brake transistor. In
an application where the motor is hardly decelerated, connecting a brake
resistor can shorten the deceleration time; no brake unit or power regeneration
converter is required. Wiring, space, and ultimately the cost will be all
saved.
Direct installation by the machine
IP55 compatible
Inverters can be
installed nearby the machine, minimizing cable length between the inverter and
motor.
· Support is
available for use even in high-humidity or dusty environments, facilitating a
more flexible choice of installation locations.
· By enclosing a DC
reactor, it requires less wiring and less space.
· Compatible with cable glands to meet the IP55 specification at the wiring section.
