0C1
Operation
release
Servo error Cause : It indicates 2 seconds has passed without making
a move since a move command was received.
1) Connection error or wire breakage on an
actuator cable
2) Brake is not released (when equipped with a
brake).
3) Load to the motor is high due to external force.
4) The resistance in the actuator sliding operation
is large.
Treatment : 1) Check the wiring condition of the actuator
cables.
2) There is a concern of a malfunction of the
controller internal components. Please contact
IAI.
3) Confirm that there is no error in the mechanical
part assembly condition.
4) If the loaded weight is within the allowable
range, turn the power OFF and check the
resistance in sliding operation by moving the
slider with hand.
0C8 Overcurrent Cause : The output current in the power circuit section is
increased abnormally.
Treatment : This alarm will not be generated in normal
operation. Degradation in insulation of motor coil
or malfunction ERC3 controller can be considered.
Please contact IAI.
0C9 Overvoltage Cause : The power voltage reached the overvoltage.
Treatment : Malfunction of a component in ERC3 controller
can be considered. Please contact IAI.
0CA
Cold start
Overheat Cause : This indicates overheat (90�C or more) of the
components inside the ERC3 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 ERC3.
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. In case the
same problem occurs again even after these
treatments, ERC3 may be considered broken.
