The heat sink panel through attachment to the FR-A520-5.5K inverter consist of the top installation frame, bottom installation frame, and upper cover. The to... More Details >>
Controlling multiple VVVFs via commun...
To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>
Encoder feedback speed accuracy
The speed variation rate is as follows: - Encoder feedback control: ±0.2% - Vector control: ±0.02% (mentioned in FR-A5AP Instruction Manual) More Details >>
The current monitor displays the average value of the three-phase current. The three-phase voltage is not incorporated for the voltage monitor. The output vo... More Details >>
Operation by single-phase power supply
Similarly to the FR-A220, single-phase power supply operation is possible by reducing the inverter's output current.Ensure that the output current is smaller... More Details >>
