The FR-A700 supports Real sensorless vector control.

Use Pr.C24 (Frequency setting voltage gain frequency built-in potentiometer).

You can use the following two methods:1. Turn ON MRS at the same time when STF turns OFF.2. Set Pr.10 = 60 Hz, Pr.11 = 0

It seems that calibration of the current input is slightly incorrect.By using Pr.904 (Frequency setting current bias) an

Connect the shield to the terminal SD.

Setting Pr.37 to the machine speed at 60 Hz switches the frequency monitor to the rotations per minute monitor.Note that

Use the FR-A5AT02 as the intercompatibility attachment when upgrading from the FR-A220-3.7K to FR-A540-3.7K.

In the A800 base of the FR-B and FR-B3, the Easy setup wizard is not available. Thus, some functions are restricted.

If Pr.361 = 0, the second terminal can be used as the line speed command when X114 is ON, and as the frequency setting v
