Alarm Name Cause/Treatment
0B6
Servo
motor
(*)
Only
when
connected
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.
0B7
Servo
motor
(*)
Only
when
connected
Cold start
Magnetic pole
indeterminacy
Cause : It shows the magnetic pole phase could not be
detected after a certain time being passed even
though the process for the magnetic pole phase
detection was executed at the first servo-on after
the power is turned ON.
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.
