Speed precision of Advanced magnetic flux vector control

The speed precision for each model is as follows:FR-K440 with PG: 1% or less of the maximum speed (3500 rpm)FR-A540 without PG (Advanced flux vector): 1% or ... 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 >>

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 >>

Analog signal resolution

The internal processing speed is not published. The analog input specifications are as follows: FR-A500???1/4000FR-E500???1/1000MR-H???1/4000 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 >>

Stall mode

Since the stall prevention function works during acceleration and the inverter does not reach the commanded speed, set Pr.156 (Stall prevention operation sel... More Details >>

Long motor wiring

When you use a long wire between the inverter and motor, pay attention to the following: 1. Since the voltage supplied to the motor terminal is reduced due t... More Details >>

Durability in multi-speed setting

1. You can set the minimum time by setting the acceleration/deceleration time and acceleration/deceleration reference frequency. 2. No problem with the termi... More Details >>

Magnetic flux and tuning

After inputting the start signal performing the tuning, output the output frequency. 　The tuning ends in approximately 500 ms in maximum after started. Durin... More Details >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>
