8.1 Action selection in case of option error
To ignore or make inverter trip can be selected in case of option error.
Item
Action selection in
case of option error
(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 Causes and Countermeasures for Option Board Errors
When any of the following alarms occurs, the inverter displays the alarm cause and stops.

(Note 1): Data in parentheses ( ) applies when the option card is connected to option slot 2.
(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.

Detect the line break or disconnection of the
encoder line.
Detect when there is an encoder failure.
Detect when the specification of the encoder is
not line driver output type.
Detect when there is no Z pulse.
Detect when the motor rotation speed exceeds
(maximum frequency (note 2))×(over speed
error detection level (P026).
(Note 3),(Note 4)
Detect when the deviation of the current
position and command value becomes more
than

Detect abnormal connection between the
inverter main body and SJ-FB.

PROTECTION FUNCTION
TRP: Inverter trips and outputs alarm signal.
RUN: Inverter ignores the option error and
continues the operation.
Check the encoder signal line and
connection.
Replace it to a suitable one.
Turn SWENC-2 OFF on the option
board.
Adjust the Kp and J constants
related to the speed control system
to reduce overshoot.
Increase the position loop gain.
Decrease the numbers of the pulse
during
position
train input per second.
Check the connection between the
inverter main body and SJ-FB.
