0E4
Encoder transmission
error
Cause : The data sent from the controller was not received properly
by the encoder side.
1) Encoder cable is partially disconnected, or connector is not
connected properly.
2) Influence from noise.
3) Failure of communication IC mounted on the encoder circuit
board.
4) Failure of communication IC mounted on the driver unit
circuit board.
Countermeasure : 1) Confirm that there is no failure in the cable and
connector coupler.
2) Try turning OFF power to all peripheral devices
and moving only the controller
and actuator. If no
error is generated, the culprit may be noise.
Take measures against noise.
3) or 4) is the case, replace the motor unit or
controller.
0E5
Encoder receipt error
Cause : This shows the data was not received in normal condition
from the encoder side to the controller.
1) Breakage of encoder cable or connection error on
connectors
(If the detail code in the alarm list of the teaching tool is
0002
H
.)
2) Effect of noise (Detail Code 0001
H
)
3) A faulty part inside the actuator (communication part).
4) A faulty part inside the controller (communication part).
5) Initialization of battery-less absolute encoder is incomplete
(Detail Code 000A
H
)
6) Error occurred in communication with battery-less absolute
encoder (Detail Code 000C
H
)
Countermeasure : 1) Check if any wire breakage on a connector and
the condition of wire connections.
2) Interrupt the power to the peripheral equipment
and activate only the actuator. If any error does
not occur, it might be caused by noise. Take
proper measures against noise.
3), 4) or 5) if it is the cause, is necessary to replace
the actuator (motor part) or controller.
6) Check a breakage of encoder cable and
connection on the connectors. For the high-
resolution battery-less absolute encoder, check
the capacity of 24V DC power supply and
connection on power supply wiring.
0E6
Encoder count error
Cause : Error status was received in initial communication with
battery-less absolute encoder
Countermeasure : Reboot the power and conduct an absolute reset
(home-return operation).
Replace the motor unit in case the condition would
not recover.

0E8
A-, B-phase
disconnection
Cause : The encoder signal cannot be detected normally.
1) Disconnection of the actuator connection cable, actuator
side attached cable, or connector connection failure.
2) Failure of the encoder itself.
Countermeasure : 1) Check for any wire breakage on a connector and
inspect the condition of the wire connections.
2) If there is no cable malfunction, encoder failure
may be possible.
0EB Battery-less absolute
encoder error detected
Cause : Battery-less absolute encoder cannot detect location
information normally.
Countermeasure : Check for any wire breakage on a connector and
inspect the condition of the wire connections.
If there is no cable malfunction, encoder failure
may be possible.
0F2
Field bus module error
Cause : Error detected in field network circuit board.
Countermeasure : Check the parameter settings.
0F3
Field bus module not
detected
Cause : Field network circuit board could not be detected.
Countermeasure : Reboot the power. Replace the controller incase
the phenomenon would not be solved.
0F4
Mismatched PCB
Cause : The PCB is not applicable for the connected motor in the
startup check.
Countermeasure : The actuator may not match the controller. Check
the model.
Should this error occur, please contact IAI.
0F5 Non-
volatile memory write
verify error
Cause : Unmatch was detected when the data was written to the non-
volatile memory and comparison (verification) was made to
see if the data inside the memory matches with the written
data. (Failure of non-volatile memory)
Countermeasure : If the same phenomenon occurs even after the
power is rebooted, it is necessary to replace the
controller.
0F6
Non-volatile memory write
timeout
Cause : There is no response within the specified time during the data
writing to the non-volatile memory. (Failure of non-volatile
memory)
Countermeasure : If the same phenomenon occurs even after the
power is rebooted, it is necessary to replace the
controller.
0F8
Non-volatile memory data
destruction
Cause : Abnormal data was detected by non-volatile memory check at
startup. (Failure of non-volatile memory)
Countermeasure : If the same phenomenon occurs even after the
power is rebooted, it is necessary to replace the
controller.
0FA CPU error
Cause : CPU is not operating normally.
1) CPU malfunction.
2) Malfunction caused by noise.
Countermeasure : If the same phenomenon occurs even after the
power is rebooted, it is necessary to replace the
controller.
