Level
Alarm Name Cause/Treatment
0D8 Deviation overflow Cause : This alarm indicates that the position deviation
counter has overflowed.
1) The speed dropped or the actuator stopped due
to the effect of external force or overload.
2) The excited-phase detection operation following
the power-on is unstable.
3) The power supply voltage dropped.
4) Servo gain number is too small
Treatment : 1) This error occurs when the actuator cannot be
operated as it is commanded. Check the load
conditions such as if the work is touching to the
surrounding object, or brake is properly
released, and remove the cause.
2) Overload can be concerned. Revise the
transportable weight and redo the home-return
operation.
3) Check for the source voltage.
0D9 Software stroke limit
exceeded
Cause : The current position of the actuator exceeds the
software stroke limit.
Treatment : Return the actuator to be within the range of the
software stroke limit.
0DC
Operation
release
Pressing motion range
over error
Cause : 1) After the pressing operation has complete, the
force to push back is too large and the pushed
back to the pressing start position (“Position” in
the position table).
2) The actuator touched the work during the
approach movement before the pressing
movement.
Treatment : 1) Revise the setting and adjust it so the force to
push back gets smaller.
2) Set the “Position” setting in front in the position
table to shorten the approach distance.
0E0
Cold start
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) Turn ON the brake release switch to see if the
brake is released.
If the brake is not released, the brake itself may
be faulty, cable may be disconnected, or the
controller may be faulty. 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.
Generating this error repeatedly without waiting long enough
could burn down the motor coil.
