Part 3 Maintenance
Code Alarm name Cause/action
0BA Home sensor not
detected
This alarm indicates that the actuator equipped with the home check sensor has not yet
successfully completed the home return operation.
Cause: [1] The work part contacted a surrounding equipment or structure during home
return.
[2] The slide resistance of the actuator is high in some location.
[3] The home check sensor is not properly installed, faulty or open.
Action: If the work part is not contacting any surrounding equipment or structure, [2] or
[3] is suspected. Please contact IAI.
0BE Home return
timeout
Cause: Home return does not complete after elapse of the time set by the applicable
manufacturer’s parameter following the start of home return operation. (This
alarm does not generate in normal operations.)
Action: The controller and actuator combination may be wrong, among others.
Please contact IAI.
0C0 Excessive actual
speed
Cause: The motor speed exceeded the maximum speed set by the applicable
manufacturer’s parameter. Although this alarm does not generate in normal
operations, it may occur if the load decreased before a servo error was detected
and the actuator moved quickly as a result, which can be caused by various
reasons including the following:
[1] The slide resistance of the actuator is high in some location.
[2] The load increased due to momentary application of external force.
Action: Check the assembly condition of mechanical parts for any abnormality.
If the actuator itself is suspected as the cause, please contact IAI.
0C1 Servo error
(RPCON only)
This alarm indicates that the motor could not be operated for 2 seconds or more after the
movement command was accepted and before the target position was reached.
Cause: [1] The motor-extension cable connector is loose or open.
[2] If the actuator is equipped with a brake, the brake cannot be released.
[3] The load increased due to application of external force.
[4] The slide resistance of the actuator itself is high.
Action: [1] Check the wiring condition of the motor-extension cable.
[2] Check the wiring condition of the brake cable. Also, turn on/off the brake
release switch and check if the brake makes “click” sounds.
[3] Check the assembly condition of mechanical parts for any abnormality.
[4] If the payload is normal, turn off the power and move the actuator by hand to
check the slide resistance.
If the actuator itself is suspected as the cause, please contact IAI.
0C9 Motor
power-supply
overvoltage
This alarm indicates that the motor power-supply voltage is excessively high (24 V + 20%:
28.8 V or above).
Cause: [1] The 24-V input power-supply voltage is high.
[2] A faulty part inside the controller
Action: Check the input power-supply voltage.
If the voltage is normal, please contact IAI.
