Level
Alarm Name Cause/Treatment
0A8 Unsupported
motor/encoder types
Cause : A motor or encoder not applicable for this controller
is connected, and the motor or encoder cannot be
classified.
Treatment : Contact us in case this alarm is issued with the
applicable actuator or occurs again even after the
power is rebooted.
0B4
Only for
A
drivers
Cold start
Electric angling
mismatching
Cause : 1) The position deviation counter is over-flown.
2) An error occurred in Z-axis detection. (When
detail code in error list of teaching tool is 0001
H
)
Treatment : 1) This error occurs when an actuator cannot
operate.
Confirm about the load conditions, that the work
does not interfere with any object nearby or the
brake has been released, etc.
If the error occurs even when the servo is ON,
the cable breakage or disconnection is
considered. Check the cable connection. Please
contact IAI if there is no failure in the cable and
connector connections.
2) Turn the power OFF and reboot. If the same
error occurs again, please contact IAI.
0B5
Only for
A
drivers
Z-phase position error Cause : The point where Z-phase was detected in
home-return operation was out of the specified
area. Encoder error
Treatment : Please contact IAI.
0B6
Only for
A
drivers
Operation
release
Z-phase detection time
out
Cause : This indicates the Z-phase could not be detected at
the first servo-on or home-return operation after the
power is turned ON in Simple Absolute type.
1) Connector connection error or wire breakage on
an actuator cable.
2) Brake cannot be released on a controller
equipped with a brake.
3) Detection of the motor is not performed properly
because an external force is applied.
4) The slide resistance of the actuator itself is large.
Treatment : 1) Check for the actuator cable wiring condition.
2) Check the wiring condition of the brake cable,
and also turn on/off the brake release switch to
see if the brake makes a “clicking” sound. If the
brake is not making any noise, check if the
power is supplied to the brake properly.
3) Check if there is any abnormality in the parts
assembly condition.
4) It the transportation weight is in the acceptable
range, cut off the power to check the slide
resistance manually by moving with hand.
If the actuator itself is suspected to be the cause,
please contact IAI.
