(Note) : Inverter trips anyway in case of encoder line break error (E60, E70), SJ-FB abnormal connection (E69,E79) occurs, although action selection is set to 01 (RUN). Please refer to "Chapter 5.2 FEED-BACK BOARD INITIAL SETTINGS".

8.2 Cause and countermeasure of the option error

When any of the following alarms occurs, the inverter displays the alarm cause and stops.

(Note 2): Frequency upper limit value (A061/A261) is reflected when it is set.

(Note 3): 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“.

(Note 4): When the over speed error occurred . There is a possibility the over speed error occur again. Even though the trip is cleared during the motor free run. In this case stop the motor, then clear the trip please.

8.3 Warning display (Feed back option relation)

(Refer to the operation manual of the main body about the warning other than the following,)

The 009 is displayed in the case that it became orientation speed setting (P015) > the highest frequency setting (A004). Please confirm the case, orientation speed setting (P015) and highest frequency setting (A004).
