0E8
Pulse
motor (*1)
Only
when
connected
Cold start
A- and B-phase wire
breaking
Cause : Encoder signals cannot be detected correctly.
1) Wire breakage or connector connection error on
an actuator cable or cable enclosed in an
actuator.
2) Malfunction of encoder itself.
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
If the cables are in the normal condition, the
malfunction of the encoder can be considered.
Please contact IAI.
0ED Absolute encoder error
detection 1
Cause : The current position has changed while controller
was reading the absolute data or saving files.
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 type encoder.
1) When the power is supplied for the first time to
Simple absolute 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 connection error on
an actuator cable or cable enclosed in an
actuator or connector being removed and
inserted.
(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).

Battery]

Absolute encoder error
detection 3
The encoder for the Simple absolute type cannot detect the
position information properly. (Encoder over speed error)
Cause : The current position changed with a speed more
than the rotation speed setting by an external
cause during the power shutoff.
Treatment : Set the rotation speed to a higher speed than what
currently is. If the same failure occurs again, it is
necessary to have an absolute reset.

Battery]

Servo
motor (*2)
Only
when
connected
Driver logic error Cause : Exceeded load, parameter (motor type)
mismatched, noise, malfunction of controller, etc.
Treatment : Please contact IAI.
0F4
Cold start
Mismatched PCB The PCB is not applicable for the connected motor in the startup
check.
Cause : There is a possibility of mismatch between the
actuator and controller. Check the model codes.
Treatment : Should this error occur, please contact IAI.
