Power supply phase loss

The following is the case for the FREQROL-A500 series:1. When the R phase or S phase is lost, the inverter stops since it loses the control power supply.2. W... 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 >>

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 >>

Outgoing harmonic current (0.1 kW, 0.2 kW)

200 V, 0.1 kW to 3.7 kW products are subject to regulation by the harmonic suppression guidelines for household appliances and general-purpose products. Ther... More Details >>

Inverter operation against power supply voltage drop

Depending on the load current, undervoltage protection (UVT) or instantaneous power failure protection (IPF) is triggered to shut off the inverter output, an... More Details >>

Installing parameter unit outside control panel

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 >>

Output current detection

The FR-A500 series that is the successor of the FR-A200E series has a function similar to output current detection of the FR-E500. Consider using the FR-A500... More Details >>

Intercompatibility attachment

Digital input and maximum frequency

1. Pr.1 and 18 limit the output to 120 Hz. Use Pr.18 to change the maximum frequency. 2. If you want to output the binary input as is, setting Pr.304 = 1 (Bi... More Details >>

Coasting operation of the inverter

To use an inverter using the external contact coast to stop (to shut off the inverter's output), short-circuit the terminals MRS and SD.For CC-Link operation... More Details >>
