Alarm
Code Alarm Level
Alarm Name Cause/Treatment
0E8
Cold start
A- and B-phase wire
breaking
Cause : Encoder signals cannot be detected correctly.
1) The motor/encoder relay cable or supplied
actuator cable is disconnected or its
connector is not plugged in correctly.
2) The encoder itself is faulty.
Treatment : 1) Check if any wire breakage on a connector
and the condition of wire connections.
If the cables are normal, faulty encoder is
suspected. Please contact IAI.
0ED Absolute encoder error
detection 1
Cause : The current position has changed while the
controller is reading or saving the absolute data.
Treatment : Avoid a condition that gives vibration to the
actuator.
0EE Absolute encoder error
detection 2
Cause : The position data cannot be detected properly in
the Simple Absolute applicable type encoder.
1) When the power is supplied for the first time
to Simple Absolute applicable type (before
executing absolute reset)
2) Voltage drop of absolute battery.
(If the detail code in the error list of the
teaching tool is 0001H.)
3) Wire breakage or connector contact failure of
motor/encoder relay cable or actuator
enclosed cables, or attempted to insert and
remove the cables
(If the detail code in the error list of the
teaching tool is 0002H.)
4) Changed the parameters of controller
Treatment : 2) Supply the power for 72 hours or more and
after charging the battery enough, perform the
absolute reset operation.
If the same failure occurs often even with
enough battery charge, it is considered the
end of the battery life. Replace the battery.
Conduct an absolute reset for 1), 2) and 4).
[Refer to Chapter 6 Absolute Reset and Absolute
Battery]
0EF Absolute encoder error
detection 3
The encoder for the Simple Absolute applicable type cannot
detect the position information properly. (Encoder overspeed
error)
Cause : The current position changed with a speed more
than the rotation velocity setting by an external
cause during the power shutoff.
Treatment : Set the rotation velocity to a higher speed than
what currently is. If the same failure occurs
again, it is necessary to have an absolute reset.

Battery]
0F1
Operation
release
Field bus link error Cause : Error detected in field network link
Treatment : Reboot the power. Please contact us if the
problem is not solved with this action.
0F2 Field bus module error Cause : Error detected in field network circuit board
Treatment : Check the parameter settings.
0F3 Field bus module not
detected
Cause : Field network circuit board could not be
detected.
Treatment : Reboot the power. Please contact us if the
problem is not solved with this action.
0F4
Cold start
Mismatched PCB The PCB is not applicable for the connected motor in the
startup check.
Cause : The actuator may not match the controller.
Check the model.
Treatment : Should this error occur, please contact IAI.
