Code Error Cause/action
0CC Excessive control
power-supply voltage This alarm indicates that the voltage of the 24-V input power supply is
excessive (24 V + 20%: 28.8 V or above).
Cause: [1] The voltage of the 24-V input power supply is high.
[2] Faulty part in the controller
Action: Check the input power-supply voltage.
If the voltage is normal, contact IAI.
0CE Low control
power-supply voltage This alarm indicates that the voltage of the 24-V input power supply is low (24
V – 20%: 19.2 V or below).
Cause: [1] The voltage of the 24-V input power supply is low.
[2] Faulty part in the controller
Action: Check the input power-supply voltage.
If the voltage is normal, contact IAI.
0D8 Deviation overflow The position deviation counter has overflowed.
0D2
Cause: The speed dropped during movement due to the effect of an external
force, etc.
Action: Check the load conditions—such as whether the load is contacting a
surrounding object or the brake is disengaged—and then correct the
abnormality, if any
0D9 Software stroke limit
overtravel error Cause: [1] The actuator installed vertically overshot and exceeded a
software stroke limit due to a large load or high deceleration
setting when the target position was set to a point near the
software stroke limit.
[2] The actuator was moved to outside the software stroke limits
with the servo turned off, and then the servo was turned on.
Action: [1] Set the deceleration curve properly so that the actuator will not
overshoot when stopping.
[2] Return the actuator to inside the software stroke limits, and then
turn on the servo.
0DC Out of push & hold
operation range error This error occurs when the actuator was pushed back to the target position
due to an excessive push force after completion of push & hold operation.
Review the entire system.
0ED Absolute encoder error
(1) Cause: [1] When the power was reconnected following the completion of an
absolute reset, the current position changed due to an external
factor, etc., while the ABS unit was communicating.
[2] When an absolute reset was performed, the current position
changed due to an external factor, etc., while the controller was
communicating with the simple absolute unit.
Action: [1] Detail code = H’0001
Turn on the power and then turn it back on in a condition where
the actuator does not receive vibration, etc.
[2] Detail code = H’0002
Perform an origin return operation again in a condition where the
actuator does not receive vibration, etc.
Cause: This error occurs when overvoltage of motor power has been
detected (38V or more)
Action: Check the motor power input voltage (MPI terminal).
In case there is no fault found in voltage, malfunction of controller
can be considered. Please contact us.
