Code
Alarm
Level
Alarm Name Cause/Treatment
0E0 Overload Cause : 1) The work piece weight exceeds the rating, or
load has increased due to external force.
2) Brake is not released in case of actuator
(equipped with brake).
3) The slide resistance of the actuator is locally
high.
Treatment : 1) Revise the work piece and peripherals, and
remove the cause.
2) Turn on the brake release switch to confirm the
brake gets released.
In case that the brake does not get released,
it can be considered a malfunction of the brake
itself, breakage of the cable or malfunction of the
controller. Please contact IAI.
3) If the work piece is in a condition that it can be
moved manually with hand, try to move it to
check if there is any spot that the sliding
resistance is large. Check if there is any
deformation on the attachment surface. Please
contact IAI if this occurs with the actuator itself.

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.
Caution:
Make sure to remove the cause before resuming the
operation. In case that confirmation cannot be made that
the cause is completely removed, leave the unit for 30
minutes or more before rebooting the power to avoid
motor coil burnout.
