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 >>

FR-A500 main circuit wire types

Since the UL standard defines to "Use copper wires (rated at 75?C)", we also recommend the same type of copper wire. More Details >>

Frequency setting

When running the inverter in Advanced magnetic flux vector control, the frequency setting value is increased by the amount of the motor's slippage, resulting... More Details >>
