8. What to do When an Error Code Occurs
Below we indicate what to do in case any of the error codes described on the preceding page appear in the 7-segment
display on the face of the controller.
(1) A1 ~ A5 alarms related to the servo
When one of these alarms related to the axis appears, determining which axis is the cause of the error makes it easier to
solve the problem. One of the ways to do this is to judge by the axis status or movement at the time the error was
generated. After the error is generated, you can try moving the axis manually if it is a small system. If the axis (when
there is no brake) moves without resistance, there is a good possibility that this is the axis causing the problem. When
these errors occur, you should ascertain the status of the actuator such as whether it was in the middle of homing.
In the case of an A2 alarm where there is excessive load, the cause of the error must be corrected. If you are unsure of the
cause, turn on the emergency stop or turn off the power and then after about 10 seconds, turn the power back on to see how
the actuator runs. If you cannot find what the trouble is, please contact IAI or one of its agents.
When there is an A3 deviation error, it is possible that something is wrong with the connector cable.
When there is an A4 error, it is almost always caused by a programming error. Recheck the program to make sure
that you are not trying to move the actuator beyond the stroke length.
When there is an A5 error, check to see how the axis is moving and then contact IAI. A5 errors can be caused by
encoder breakdown, cable problems or driver problems.
Does the error occur at the same
time you turn the power ON?
Checklist
Does the error occur before you try to
home the actuator?
The actuator performs homing and
then the error occurs.
There is no problem with homing but an
error occurs during automatic operation.
Is there excessive load?
Is the speed correct? Are you trying to stop a vertical axis
when loaded?
