0E0
Servo
motor (*)
Only when
connected
Overload Cause : 1) The work weight exceeds the rated weight, or an
external force is applied and the load increased.
2) If the actuator is equipped with a brake, the
brake is not released.
3) The slide resistance of the actuator is locally
high.
Treatment : 1) Check the work and its surrounding area to
remove the cause.
2) If an improvement can be confirmed when 24V
DC, 150mA is supplied to BKRLS terminal in the
external brake input connector, a malfunction of
the controller can be considered. Please contact
IAI. If the error cannot be cancelled, malfunction
of brake, cable breakage or controller
malfunction can be considered. Please contact
IAI.
3) In the case that the work can be moved by hand,
move it. Then, check that there is no location
where a sliding resistant is too large. Check if
the installation face is distorted. When the error
occurs in operation of the actuator only, Please
contact IAI.
Caution
Restart the operation after making sure to remove the cause.
If you cannot determine that the cause is removed completely,
wait for at least 30 minutes before turning ON the power to
prevent the motor coil from burning.
0E5 Encoder receipt error Cause : This indicates that the data was not received to the
controller in the normal condition from the simple
absolute area.
1) Connector connection error (If the detail code in
the error list of the teaching tool is 0002H.)
2) Effect of noise (If the detail code in the error list
of the teaching tool is 0001H.)
3) Malfunction of component (communication part)
inside the controller.
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 this actuator and actuator.
If any error does not occur, it might be caused by
noise. Take proper measures against noise.
3) It is necessary to replace the actuator (motor
part) or controller.
If the cause cannot be specified, please contact IAI.
0E7
Servo
motor (*)
Only when
connected
Cold start
A-, B- and Z-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.
