Alarm
Code Alarm Level
Alarm Name Cause/Treatment
0CA Overheat Cause : This indicates overheat (90qC 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.
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.

Drop in control supply
voltage
Cause : The control power voltage dropped less than the
voltage drop threshold (80% of 24V DC = 19.2V).
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.
0D4
Cold start
Drive Source Error Cause : 1) Motor power input voltage (input to MPI
terminal) is too large
During acceleration/deceleration and
servo-on, 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.
2) Overcurrent is generated on the motor power
supply line.
Treatment : 1) Check the power voltage input to MPI
terminal. Think to use a power supply with
enough current capacity or not to use the
remote sensing function.
2) Check the wire layout between the actuator
and controller.
