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) Encoder cable is about to break or connector is
not plugged properly
2) Effect of noise
3) One or more communication ICs installed on the
encoder board are faulty.
4) One or more communication ICs installed on the
controller board are faulty.
Treatment : 1) Check on the cables and the connector joints to
see if any abnormality.
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, 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.
(If the detail code in the error list of the teaching
tool is 0002
H
.)
2) Effect of noise.
(If the detail code in the error list of the teaching
tool is 0001
H
.)
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.
