Pulse

connected
Cold start
Excitement detection
error
Cause : The magnetic pole phase detection is not
completed after a certain time being passed even
though the detection process was executed at the
first servo-on after the power is turned ON.
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) Power was turned ON while touching to the
mechanical end.
5) The resistance in the actuator sliding operation
is large.
Treatment : 1) Check the wiring condition of the actuator cables.
2) If an improvement can be confirmed when 24V
DC, 150mA is supplied to BKRLS terminal in the
external brake input connector, a malfunction of
the controller can be considered. 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.
0BA Home sensor
non-detection
Cause : This indicates that the home-return operation of the
actuator equipped with origin sensor (option for
those except for rotary actuator) is not completed in
normal condition.
1) The work piece has interfered with the
peripherals during the home-return operation.
2) The resistance in the actuator sliding operation
is large.
3) Attachment error, malfunction or wire breakage
of origin sensor.
Treatment : If there is no interference of the work piece
confirmed with the peripherals, 2) or 3) can be
considered as a cause. Please contact IAI.
0BE 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.
0C0
Operation
release
Actual speed excessive Cause : This indicates the number of motor rotation
exceeded the number of allowable rotation.
1) The slide resistance of the actuator is locally high.
2) The load is increased too much due to a external
force.
With the reasons above, it can be considered a
sudden speed increase has occurred before
detecting the servo error.
Treatment : Even though this would not occur in normal
operation, check if there is any abnormality in the
parts assembly condition. Also check if there is a
possibility that an external force may be applied in
the direction of the actuator movement.
