Designed for unparalleled drive precision, speed control, simple start-up, and versatility, Mitsubishi Electric has developed a new generation of drive technology used in the FR-A800. It is equipped with the new state-of-the-art high-speed processor by Mitsubishi Electric to provide better control and response level, for safe and accurate operations in a diverse range of applications.

In addition to its high performance pedigree, the new FR-A800 from Mitsubishi Electric UK is no slouch when it comes to optimising energy saving.

Energy saving functions

Take advantage of the energy saving function that suits your application. You can for example reduce power consumption in the standby mode by using the cooling fan ON/OFF control. During operation optimum excitation control or returning regenerative motor energy to other drives helps to save energy. The impressive energy savings can be displayed on the energy monitor.

Optimum excitation control

Optimum control of the excitation current maximizes motor efficiency for additional energy savings. As an example, an approximately 15 % increase in efficiency is obtained at a motor load torque of 10 % compared to conventional V/F control.

Energy saving by 24 V control power supply

By connecting an external 24 V DC control power supply, the system can be operated even when the main power supply is turned off. Furthermore parameters can be set and network communication can be maintained with this power supply which facilitates safe maintenance. More energy saving can be achieved by using the automatic “stand by” function which switches off the drive main power supply. Capacitors and other devices are offline, so heat loss is reduced.

Perfect auto-tuning of PM and IM motors

The FR-A800 series new auto-tuning method enables factory energy savings, which can be achieved by replacing current induction motors with permanent magnet motors (PM motors). A PM motor is very efficient because the current does not flow to the rotor, so there is no secondary copper loss. There is also magnetic flux generated by permanent magnets, so less current is required to drive a motor.
