Alarm
Code Alarm Level
Alarm Name Cause/Treatment
0A8 Unsupported
motor/encoder types
Cause : The motor connected to the controller is not
applicable or the type of the encoder that the
motor is connected is not applicable.
Treatment : Please contact us if the alarm is issued even with
the applicable actuator and the same problem
happens again even after rebooting the power.
0B8
Cold start
Excitement detection
error
Cause : In this controller, the excitation detection starts
when the servo is turned ON for the first time
after the power is supplied. The detection is not
finished after a certain time (set to Parameter
No.29) being passed.
1) Connection error or wire breakage of
motor/encoder cables.
2) Brake is not released (when equipped with a
brake).
3) Load to the motor is high due to external
force.
4) Power was turned on while touching to the
mechanical end.
5) The resistance in the actuator sliding
operation is large.
6) Parameter No.22 Home Return Offset was set
smaller than the initial value.
Treatment : 1) Check for the motor/encoder cable wiring
condition.
2) Supply 24V DC 150mA to the BKRLS terminal
on the power supply connector and if you can
see an improvement, it is considered the
controller failure. Please contact IAI.
3) Confirm that there is no error in the
mechanical part assembly condition.
4) Move the slider or the rod to a point where it
would not hit the mechanical end and reboot
the system.
5) 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.
6) For Simple Absolute Type, the excitation
detection is performed at the end of home
return operation. If the Parameter No.22
Home Return Offset is set smaller than the
initial setting, the actuator interferes with the
mechanical end and excitation detection
cannot be performed properly.
0BA Home sensor
non-detection
Cause : This indicates that the home-return operation of
the actuator equipped with origin sensor (option
except rotary actuator) is not completed in
normal condition.
1) Work is interfering with peripheral equipment
in the middle of home return.
2) Large slide resistance of the actuator itself
3) Installation failure, breakdown or
disconnection of the home sensor
Treatment : In the case that the work does not interfere with
anything, the cause 2) or 3) is supposed. In such
case, please contact IAI.
0BE
Operation
release
Home return timeout Cause : Home return does not complete after elapse of a
certain period after the start of home return.
Treatment : This error does not occur in normal operation.
The combination of the controller and actuator
may be incorrect. Please contact IAI.
