Alarm Name Cause/Treatment
0E3 Loadcell error Cause : Loadcell power error, hardware error such as board
overheat or EEPROM error occurs.
Treatment : 1) The effect of noise may be possible. Check the
presence of noise source around the loadcell.
2) Replace the loadcell if it may be faulty. Please
contact IAI.
0E4 Encoder send error Cause : The data sending and receiving between the
controller and encoder is conducted by the serial
communication. This error indicates that the data
sent from the controller was not received properly at
the encoder side.
1) Effect of noise
2) One or more communication ICs installed on the
encoder board are faulty.
3) One or more communication Ics installed on the
controller board are faulty.
Treatment : 1) 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.
If 2) or 3) is the case, the encoder or controller must
be replaced.
If the cause cannot be specified, please contact IAI.
0E5 Encoder receipt error Cause : This shows the data was not received in normal
condition from the encoder side to the controller.
1) Cable breakage of encoder cable or connector
connection failure or noise.
(If the detail code in the error list of the teaching
tool is 0001H.)
2) Effect of noise.
(If the detail code in the error list of the teaching
tool is 0002H.)
3) Malfunction of component (communication part)
inside the actuator.
4) A faulty part inside the controller (communication
part).
Treatment : 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.
If 3) or 4) is the case, it is necessary to replace the
actuator (motor part) or controller.
If the cause cannot be specified, please contact IAI.
0E6
Cold start
Encoder count error Cause : This error code appears when the encoder cannot
detect the position information properly.
1) The encoder relay cable or supplied actuator
cable is disconnected or its connector is not
plugged in correctly.
2) Foreign matter is deposited on the code wheel.
3) The position relationship between the code
wheel and photo sensor changed due to shaft
center shift caused by application of excessive
external force, etc.
4) Faulty encoder board component
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
For the case of 2), 3) or 4), it is necessary either to
clean the code wheel, adjust the installation
position, replace the motor unit or replace the
actuator. In any case, please contact IAI.
