Alarm Name Cause/Treatment
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) Component malfunction in ERC3 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
Operation
release
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) Component malfunction in ERC3 controller
Treatment : Check the voltage of the power supply.
In the case that the voltage is normal, please
contact IAI.
0D4 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.
0D5
Cold start
Differential Counter
Overflow with Home
Return Incomplete
Cause : This alarm indicates that the position deviation
counter has overflowed.
1) The speed dropped or stopped during JOG
move due to an impact of external force, hit to
the mechanical end or overload.
2) The excited-phase detection operation
following the power-on is unstable.
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 is concerned. Revise the
transportable weight.
