The FR-A series, with its enhanced real sensorless vector control and vector control, meets the needs of all machinery types.
Offering 100Mbit Ethernet TCP/IP connectivity as standard, in addition to existing network options, the FR-A800-E provides increased capabilities within remote system monitoring and parameter adjustment, as well as easy integration into existing network environments.
Precise, powerful, versatile
Designed for unparalleled drive precision, speed control, simple startup, and versatility, Mitsubishi Electric has developed a new generation of drive technology: the remarkable FR-A800.
Some of the outstanding features are the integrated high-level PLC, USB port for programming and parameter copying, an-easy to-read control panel, optimum power usage and energy-saving functions, improved system safety, three expansion slots for a range of option and supported network card.
The FR-A800 Series is backwards compatible with the FR-A700 series. Parameters can be easily copied by FR Configurator2. In order to match the former machine response time, the input/output signals of the FR-A800 can be delayed.
Powerful features and intelligent functions
The FR-A800 series has a two-channel emergency stop for safe shutdown. This ensures safe operation in compliance with the European Machinery Directive without installation of another contactor. The FR-A800 thus conforms to the EN ISO13849-1/PLe cat. 3, EN 61508-1/-2/-3:2010(SIL3) and EN 61800-5-2 SIL3 standards.
The operation panel with the one-touch Digital Dial allows direct access to all important parameters. The FR-A800 series also allows easy connection of a Mitsubishi Electric graphical operation terminal (GOT DRIVE). Communication parameters for the HMI connection are automatically set as a batch.
The drive’s built-in EMC filter ensures full compliance with European EMC Directive standards (EN 61800-3 2nd environment category C3), so separate certification is not required for the drive.
Take advantage of the energy-saving function, that suits your application. The impressive energy savings can be displayed on the energy monitor.
The cooling fans and the built-in capacitors have an estimated lifespan of 10 years. By using the ON/OFF control function, the service life of the fans can be even further extended.
Various network compatibility
The drive can be controlled and monitored by a controller via the network. For the major network protocols such as CC-Link IE Field, CC-Link IE Field Basic, Modbus TCP, CC-Link, Profibus DP/DPV1, Profinet/Ether- Net IP/EtherCat and SSCNETIII/H as well as DeviceNet™ and LONWORKS communication options are available. RS485 communication (Mitsubishi Electric drive protocol, Modbus-RTU protocol) is supported as an option.

This compact frequency inverter offers exceptional performance and is ideal for hoist drives and high-powered machines where the torque can be used for regenerative braking.
Conserves energy, cuts costs
Featuring a large number of innovative technologies, this compact frequency inverter delivers exceptional performance and is ideal for hoist drives and high-powered machines with torque that can be used for regenerative braking. This includes a wide range of applications with vertical and horizontal movements such as conveyor systems, centri- fugal separators, testing machines, winding machines and so on.
The FR-A741 both reduces your initial investment outlay and keeps operating costs low. The integrated power regeneration function makes it possible to use smaller and much less expensive drive systems and enables simpler and more compact switchgear cabinet layouts.
High power saving potential
Cutting energy consumption and protecting the environment are now key issues in mechanical and plant engineering. Drive motors usually account for most of the power used and they also take up lots of space and require special cooling facilities. The FR-A741’s regenerative braking system makes it much more efficient than conventional drive systems, giving it the potential for significant energy savings.
The integration of the frequency inverter and power regeneration system in a single unit reduces space requirements, making installation in the switchgear cabinet much simpler.
The combination of the integrated AC reactor and no need for an external braking unit eliminate a large amount of additional wiring. These inverters need up to 60 % less main circuit wiring and occupy up to 40 % less space than conventional solutions, depending on the output capacity. The result is significantly less overall cable lengths and switchgear cabinet space requirements.
Ideal for hoisting applications
The frequency inverters of the FR-A741 series are innovative and intelligent drive systems that can easily be integrated in complex applications. They are particularly well suited for tasks involving frequent cyclical acceleration and deceleration and in all applications where braking resistors are normally used.
Special crane programming functions are supported for easy integration in hoisting applications, including a special external brake control sequence, functions for load-based speed switching and four independent torque thresholds for all four quadrants.
- Integrated power regeneration enhances energy efficiency
- Much lower installation overheads, more effective system planning, simpler switchgear cabinet layout
- High-end drive with a wealth of application functions
- Lower TCO than conventional solutions
