Difference between use with A100 and other types

Similarly to the FR-A200 and A500, four or more filters should be used also for the FR-A100. 　In short, it is OK if the wire penetrates the filter four times... More Details >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Heat generation quantity of FR-A500

The heat generation quantity of the FR-A520-5.5K is 310 W. (Reference: The heat generation quantity of the FR-A220E-5.5K is 330 W.) For other capacities, ref... More Details >>

Countermeasure against inverter noise

You can attach the following filters to the inverter input side:- Line noise filter (FR-BLF, FR-BSF01)- Radio noise filter (FR-BIF) 　While it is a good idea ... More Details >>

How many inverters can be connected?

Up to 32 units can be connected. (This is because the inverter communication conforms to RS-485.) More Details >>

Brake unit selection

1. The BU brake unit does not have the fault output.Multiple BU brake units can be connected in parallel.2. Power supply voltage 480 V- What resistance value... More Details >>

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. More Details >>

Influence on inverter at motor coasts to stop

An induction motor does not act as a power generator unless voltage is applied to it.Therefore, just rotating due to coasting does not affect the inverter. More Details >>

I want to display the speed on an analog meter.

As the inverter does not display the speed in m/min, let us explain using the speed display in r/min. In this case, set Pr.52 to "6" (operation panel display... More Details >>
