Alarm
Code
Alarm
Level
Alarm Name Cause/Treatment
0CA Overheat Cause
: This indicates overheat (90 ° C or more) of the
components inside the controller.
1) Operation is performed with the load condition
exceeding the specified range.
2) High temperature around the controller.
3) Load to the motor is high due to external force.
4) A faulty part inside the controller.
Treatment : 1) Revise the operation condition such as
decreasing the acceleration/deceleration speed.
2) Lower the ambient temperature of the controller.
3) Confirm that there is no error in the mechanical
part assembly condition.
(Note) This error would not normally occur. If it occurs, confirm
there is not 1) to 3) above. If the same error is issued
again even after confirming 1) to 3) is not in the condition,
it is considered to be a malfunction. Please contact IAI.
0CB Current sensor offset
adjustment error
Cause : An error was found to the sensor in the status check
of the current detection sensor conducted at the
initializing process in the startup.
1) A breakdown of the current detection sensor or
peripheral component is supposed.
2) An error in the offset adjustment is supposed.
3) The actuator has moved by an external force at
the time the power was turned on.
Treatment : In case the same error occurs even after rebooting
the power in a condition that the actuator does not
move, it is necessary to replace the PC board or
adjust the offset.
Please contact IAI.
0CC
Cold start
Control power source
voltage error
Cause : The control power voltage dropped less than the
voltage drop threshold (120% of 24V DC = 28.8V).
1) The voltage of 24V DC power supply is high.
2) A faulty part inside the controller.
3) During acceleration/deceleration and servo-on
that use the remote sensing function of 24V DC
power supply, the current consumption rises
transiently.
Using the remote sensing function with a power
supply with no enough current capacity may
cause overvoltage responding to the current
change.
Treatment : 1) 2) Check the voltage of the power supply.
3) Think to use a power supply with enough current
capacity or not to use the remote sensing
function.
In the case that the voltage is normal, please
contact IAI.
0CE Drop in control supply
voltage
Cause : The control power voltage dropped less than the
voltage drop threshold (70% of 24V DC = 16.8V).
1) The voltage of 24V DC power supply is low.
2) A faulty part inside the controller.
Treatment : Check the voltage of the power supply.
In the case that the voltage is normal, please
contact IAI.
0D2
For
P6AC
and
P6DC
only
Operation
release Motor power source
voltage excessive
Cause : A malfunction of a component inside the controller
can be considered.
Treatment : If this error occurs often, there is a concern of a
controller malfunction. Please contact IAI.
