It is not activated because the function itself is disabled.

Check the setting value of Pr.37 (Speed display). When the machine speed is set, Pr.811 is disabled. Change the setting

Install the resistor between the terminals PC and OH.

The leakage current is 1 mA because the circuit constant in the EMC filter of A720-0.4K and 0.75K are different.

The initial value of Pr.872 is set to "1" (Valid) because the A701 have regeneration unit built-in and an overvoltage ma

It is protected not by observing the temperature directly, but by estimating it from the current value, output frequency

The following reasons are possible. - The signal of Z phase does not exist. (It is not returned normally.) - The setting

The brake unit operates when the bus voltage exceeds the brake operation voltage.

"E.OSD" occurs when the rotation speed is not decreased for one second despite the start command (STF, STR) is turned OF

Setting the tuning data without tuning makes no difference. The tuning method of the FR-A700 is different from that of V
