Inverters-FREQROL FR-A800 Series ECO-FRIENDLY FACTORIES

ECO-FRIENDLY FACTORIES

The power consumption by motors is said to amount about the half of all power consumption made by the Japanese manufacturing industry.
Factories can save more energy without dropping their production.
Less energy and more production—the FR-A800 series will help you to get the both.

Save energy while increasing factory production.

Energy-saving function tailored to system, application

Variety of functions

●Check the energy saving effect at a glance

• You can check the energy saving effect on the energy saving monitor.
• The measured output power amount can be output in pulses.

●Reduce power consumption during standby

• Control circuits other than those for power-related parts can be operated with 24 VDC power supplied from an external power source. NEW
  Since the control circuit can use the external 24 VDC, other power control circuits can stay OFF while no driving is required, and that saves the standby energy.
• By turning the cooling fan ON/OFF based on the inverter status, wasteful power consumption during stoppages can be reduced.

●Save energy with Optimum excitation control NEW

The excitation current is constantly adjusted to drive the motor in the most efficient method which leads to energy saving.
For example, with optimum excitation control with motor load torque of 10% when using the SF-JR, motor efficiency has increased by approximately 15% over the previous V/F control method.

●Effective use of regenerative energy (option)

Multiple inverters can be connected to the power regeneration common converter (FR-XC)/high power factor converter (FR-HC2) via a common PN bus.
Regenerative power is used at other inverters, and surplus energy is returned to the power supply, resulting in energy saving. The 315K or higher models are inverter-converter separated types, which are suitable for power regeneration. NEW

PM motor contributes to the energy saving in factories

PM motor

If the inverter is being used for an application requiring constant-torque, such as a conveyor, factory energy savings can be achieved by replacing your current induction motors with permanent magnet motors (PM motors).
(Tuning is required for an IPM motor other than MM-CF, and for the PM motors of other manufacturers.)

●Why is a PM motor so efficient?

• The current does not flow to the rotor (secondary side), so there is no secondary copper loss.
• Magnetic flux is generated by permanent magnets, so less current is required to drive a motor.

Conveyor

A conveyor transports different goods and products according to its application. A PM motor can keep the carrying speed constant while saving energy.
