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 ab-
normal 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 1): ( ) shows 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 er-
ror occur again. Even though the trip is cleared during the motor free run. In this
case stop the motor, then clear the trip please.

(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 set-
ting (P015) and highest frequency setting (A004).

Contents
Detect the line break or disconnection of the
encoder line.
Detect when there is an encoder failure.
Detect when the specification of the en-
coder is not line driver output type.
Detect when there is no Z pulse.
Detect when the motor rotation speed ex-
ceeds (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 1,000,000 pulses during position
controlling.
Detect abnormal connection between the
inverter main body and SJ-FB.

TRP: Inverter trips and outputs alarm signal.
RUN: Inverter ignores the option error and
01
continues the operation.

PROTECTION FUNCTION

Processing
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 re-
lated to the speed control system
to reduce overshoot.
Increase the position loop gain.
Decrease the numbers of the
pulse train input per second.
Check the connection between
the inverter main body and SJ-FB.
