code
Alarm name Causes/countermeasures
0E8
P, A, D
Driver
limited
A-, B-phase
disconnection
Cause: The encoder signal cannot be detected normally.
1) Disconnection of the actuator connection cable, actuator
side attached cable, or connector connection failure.
2) Failure of the encoder itself.
3) Disconnected axis parameter No. 158 "Enabled/Disabled
Axis Select" is 0: Enabled.
Countermeasure: 1) Check for any wire breakage on a connector and
inspect the condition of the wire connections.
2) If there is no cable malfunction, encoder failure
may be possible. Contact IAI.
3) Parameter No. 158 "Enabled/Disabled Axis
Select" 1: Disabled.
* When the actuator is not connected, this alarm is
generated just by setting the reserved axis in the
gateway parameter configuration tool or setting
the driver unit to "Not set".
0EB
P, A
Driver
limited
Battery-less Absolute
Encoder error detected
Cause: Battery-less absolute encoder cannot detect location
information normally.
Countermeasure: 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.
0EC
D
Driver
limited
PS-phase disconnection Cause: The encoder signal cannot be detected normally.
1) Disconnection of the actuator connection cable, actuator
side attached cable, or connector connection failure.
2) Failure of the encoder itself.
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.
0F0
A, D
Driver
limited
Driver logic error
Cause: Excessive load, parameter (motor type) mismatch, noise,
RCON system failure, etc.
Countermeasure: Contact IAI.
0F4
P, A
Driver
limited
PCB mismatch Cause: The circuit board is not supported by the connection motor at
startup check.
There may be a mismatch between the actuator and driver
unit. Check the model numbers.
Countermeasure: Contact IAI if this error occurs.
0F5
S
Driver
limited
Non-volatile memory write
verify error
Cause: When data is written to the non-volatile memory, comparison
(verification) is performed to confirm whether the data in the
memory matches the write data. At this time, a mismatch was
detected. (Failure of non-volatile memory)
Countermeasure: Contact IAI if this reoccurs even after turning ON the
power again.
0F6
Non-volatile memory write
timeout
Cause: There is no response within the specified time during the data
writing to the non-volatile memory. (Failure of non-volatile
memory)
Countermeasure: Contact IAI if this reoccurs even after turning ON the
power again.
