Part 3 Maintenance
Code Alarm name Cause/action
0CB Current-sensor
offset adjustment
error (RACON
only)
When the controller is started, the condition of the current detection sensor in the
controller is checked as part of the initialization process. This alarm indicates that an error
was found in this sensor during the check.
Cause: [1] Faulty current detection sensor or surrounding part
[2] Inappropriate offset adjustment.
Action: The board must be replaced or the offset must be adjusted.
Please contact IAI.
0E0 Overload
(RACON only)
Cause: [1] The load increased due to application of external force.
[2] If the actuator is equipped with a brake, the brake cannot be released.
[3] The slide resistance of the actuator is high in some location.
Action: [1] Review the condition around the work part. If the work part is receiving any
abnormally high external force, make the necessary corrections.
[2] Turn on the brake release switch to see if the brake is released. If the brake
is not released, a faulty brake, cable disconnection or defective brake-circuit
component in the controller is suspected, among others.
[3] If the work part can be moved by hand, do so to check for locations where
the slide resistance increases.
If [2] or [3] is the case, please contact IAI.
Note: Be sure to remove the cause of the alarm before resuming the operation. If the
power was cut off, wait for at least 30 minutes before turning on the power again
to prevent the motor coil from burning.
0E5 Encoder receive
error
Cause: [1] The controller power was turned on before the simple absolute unit when
the 24-V power was input.
[2] When the detail code is H’0001:
The controller is unable to communicate with the absolute unit properly due
to noise, etc.
[3] When the detail code is H’0002:
The controller is unable to communicate with the absolute unit properly due
to a disconnected communication wire in the encoder cable, etc.
Action: [1] Turn on the power to the simple absolute unit before (or simultaneously
with) the controller power.
[2] Change the installation location of the controller. Implement noise
elimination measures such as providing a FG, noise filter, clamp filter, etc.
[3] Check the encoder-extension cable between the controller and simple
absolute unit for looseness. If necessary, replace the cable.
