Positioning error

 

 

Connection abnormal of SJ-FB

(Note 1): The main body setting or external input is selectable.

SJ-DG (digital input option board) is required in case of external input.

(Note 2): It depends on what type of main body combines with the SJ-FB, the setting value conversion is different.

Please refer to the (Note 3) of the “5.3 Items regarding the feed back board of the inverter main body“.
