Alarm
Level
Alarm Name Cause/Treatment
0E7
Only for
A
drivers
A-, B- and Z-phase wire
breaking
Cause : Encoder signals cannot be detected correctly.
1) Wire breakage or connector connection error on
an actuator cable or cable enclosed in an
actuator.
2) Malfunction of encoder itself.
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
If the cables are in the normal condition, the
malfunction of the encoder can be considered.
Please contact IAI.
0E8 A- and B-phase wire
breaking
Cause : Encoder signals cannot be detected correctly.
1) Wire breakage or connector connection error on
an actuator cable or cable enclosed in an
actuator.
2) Malfunction of encoder itself.
3) Parameter No. 158 “Valid Axis / Invalid Axis
Select” of unconnected axis is set to 0: Enabled.
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
2) If the cables are in the normal condition, the
malfunction of the encoder can be considered.
Please contact IAI.
3) Set Parameter No. 158 “Valid Axis / Invalid Axis
Select” to 1: Disabled.
* If there is no actuator connected, this alarm will
occur even with a check mark on the reserved
axis in the setting described in 2.5.3 Number of
Mounted Axes, or with the drive unit set to “No
Setting”.
0EB
Only for
P and A
drivers
Battery-less absolute
encoder error detection
Cause : It is a condition that the battery-less absolute
encoder cannot detect the position information
correctly.
Treatment : Check if any wire breakage on a connector and the
condition of wire connections.
If the cables are normal, faulty encoder is
suspected. Please contact IAI.
0EC
Only for
D
drivers
Cold start
PS-phase wire breaking Cause : Encoder signals cannot be detected correctly.
1) Wire breakage or connector connection error on
an actuator cable or cable enclosed in an
actuator.
2) Malfunction of encoder itself.
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
If the cables are in the normal condition, the
malfunction of the encoder can be considered.
Please contact IAI.
