12-bit digital input

You can set both the BCD code and binary code inputs within the range from 0 to 400 Hz.You can set the bias and gain in 0.01 Hz units.For BCD input, when the... More Details >>

I want to display the speed on an ana...

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 >>

Faults history upon power failure

When an instantaneous power failure of 100 msec or longer occurs, the inverter is reset* and it is not recognized as a fault. Since it is not recognized as a... 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 >>

"Err" displayed at power-ON

This error is displayed when the inverter and operation panel FR-PU04 cannot communicate with each other correctly or the reset signal remains ON. Therefore,... More Details >>

Torque characteristic at low speed

Torque is not guaranteed for slower than 0.5 Hz. Therefore, no data for this is published. Also, no torque is generated at 0 Hz. More Details >>
