Encoder feedback control wire

If the phase A and phase B are connected reversely, encoder feedback control is not performed. Instead, the inverter is operated in normal control (V/F contr... More Details >>

Amount of heat

The inverter (FR-A520-5.5K) itself generates approximately 310 W of heat. This is the amount generated under the inverter rated current 100% load. Since the ... 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 >>

CC-Link

Although you specify the FR-V200 and others as the inverter models, CC-Link is currently supported by the FR-A500 and FR-E500. The FR-V200E does not support ... More Details >>
