Encoder reception error
Cause: Data from the encoder was not normally received by the driver
unit.
1) Encoder cable line breakage or connector connection failure
(when the detail code in the teaching tool alarm list is
0002H)
2) Influence from noise (Detail code 0001H).
3) Actuator internal part malfunction (communication part).
4) Driver unit internal part malfunction (communication part).
[Only for P Driver]
5) Initialization of battery-less absolute encoder incomplete
(Detail code 000AH)
6) Communication error occurred to battery-less absolute
encoder
(Detail code 000CH)
Countermeasure: 1) Check for any wire breakage on a connector and
inspect the condition of the wire connections.
2)
Try turning OFF power to all peripheral devices and moving
only the driver unit and actuator. If no error is generated,
the culprit may be noise. Take measures against noise.
In case of 3), 4) or 5), replace the actuator (motor
part) and/or the driver unit.
6) Check the encoder cable line breakage and
connection at connectors. For the high-resolution
battery-less absolute encoder, check the capacity
of the 24V DC power source and connection at
the power supply cables.
Contact IAI if the cause cannot be determined.

Driver
limited
Encoder count error
Cause: The encoder cannot detect location information properly.
1) Disconnection of the encoder relay cable or actuator side
attached cable, or connector connection failure.
2) Failure of the encoder itself.
3) An error response status was received during initial
communication with battery-less absolute encoder.
Countermeasure: 1) Check for any wire breakage on a connector and
inspect the condition of the wire connections.
If there is no cable malfunction, encoder failure may
be possible. Contact IAI.
0E7

Driver
limited
A-, B- and Z-phase wire
breaking
Cause: Encoder signals cannot be detected correctly.
1) The encoder relay cable or supplied actuator cable is
disconnected or its connector is not plugged in correctly.
2) The encoder itself is faulty.
Countermeasure: 1) 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.
