Alarm
Level
Alarm Name Cause/Treatment
0EB
For
P6PC
and
P6AC
only
Battery-less ABS error Cause : It is a condition that the battery-less absolute
encoder has not detected the position information
properly.
Treatment : Check if there is any breakage on the connectors
and the condition of connections.
Malfunction of the encoder can be considered if
the cables are in the normal condition. Please
contact IAI.
0EC
For
P6DC
only
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.
0ED
For
P6PC
and
P6AC
only
Absolute encoder error
detection 1
Cause : The current position has changed while the
controller is reading or saving the absolute data.
Treatment : Avoid a condition that gives vibration to the
actuator.
0EE
For
P6PC
and
P6AC
only
Absolute encoder error
detection 2
Cause : The position data cannot be detected properly in the
encoder.
1) Changed the parameters of controller
2) Position data loss in absolute reset
(If the detail code in the error list of the teaching
tool is 0006
H
or 0022
H
.)
3) Motor has replaced in battery-less absolute
type, and the pairing ID registered in the
controller has changed. (When the detail code is
000BH or 0020
H
in the error list on the teaching
tool)
Treatment : Conduct an absolute reset.
[Refer to Chapter 7 Absolute Reset]
0EF
For
P6PC
and
P6AC
only
Operation
release
Absolute encoder error
detection 3
Cause : The encoder for the Simple absolute type cannot
detect the position information properly. (Encoder
over speed error)
The current position changed with a speed more
than the rotation speed setting by an external cause
during the power shutoff.
Treatment : Set the rotation speed to a higher speed than what
currently is. If the same failure occurs again, it is
necessary to have an absolute reset.
[Refer to Chapter 7. Absolute Reset]
0F0
For
P6AC
and
P6DC
only
Driver logic error Cause : Exceeded load, parameter (motor type)
mismatched, noise, malfunction of controller, etc.
Treatment : Please contact IAI.
0F4
For
P6PC
and
P6AC
only
Cold start
Mismatched PCB The PCB is not applicable for the connected motor in the startup
check.
Cause : The parameter may not match. Check the model.
Treatment : Should this error occur, please contact IAI.
