Inverter's heat generation quantity

The heat generation quantity while the inverter is outputting the rated current is as follows:1. FR-A520-3.7K: 230 W2. FR-A520-7.5K: 420WThe heat generation ... More Details >>

Pulse train output of terminal FM

Under Advanced magnetic flux vector control, the output frequency varies due to slip compensation. This may cause the output frequency monitor value to chang... More Details >>

Winding control

As an example, you can use an inverter to feed the cord at the constant speed under dancer control using a combination of the deviation detector and deviatio... More Details >>

Brake resistor

Connecting the brake resistor allows for quick deceleration because the regenerative power is processed. (The brake torque increases.)Therefore, when an exte... More Details >>

You can install the operation panel FR-DU04 (or parameter unit FR-PU04) on the enclosure surface by connecting it with the inverter via a cable.To do this, d... More Details >>

Inverter control power supply

To supply power via R1 and S1, 60 VA or higher is necessary for 22K or lower and 80 VA or higher is necessary for 30K to 55K.Note that the rush current of ap... More Details >>
