Operation with CC-Link

1. By changing RWw1 while RYD is ON, you can change the inverter's frequency.You cannot do this with RYE. You need to turn OFF and then ON RYE each time you ... More Details >>

Motor heat generation at low-speed operation

When using the FR-A540-3.7K in Advanced magnetic flux vector control, operating the motor continuously under the 100% torque at up to 3 Hz does not cause a h... More Details >>

Heat generation quantity of FR-A500

400 Hz output setting

Change Pr.18 (High speed maximum frequency) to 400 Hz.If you are using the analog command to set the frequency, calibrate the 400 Hz frequency with Pr.903. 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 >>

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 >>

Overcurrent at low speed

"8" display in offline auto tuning means forced stop by the operator. This means that you stopped operation before tuning completes. 　With this forced stop, ... More Details >>
