Alarm
Level
Alarm Name Cause/Treatment
0E7 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.
Treatment : 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.
0EE Absolute encoder error
detection 2
Cause : This is the condition where the position information
can not be detected in the absolute encoder.
1) Voltage drop of absolute battery.
2) The encoder relay cable or supplied actuator
cable is disconnected or its connector is not
plugged in correctly.
Treatment : 1) Check the PIO battery alarm output (*BALM) and
when it is turned OFF, replace the absolute
battery with new one.
2) Check if any wire breakage on a connector and
the condition of wire connections.
Whichever action is taken under 1) or 2), an
absolute reset must be performed.
If the cables are normal, faulty encoder is
suspected. Please contact IAI.
0EF Absolute encoder error
detection 3
Absolute encoder is not detecting the position information
properly. (ABS encoder overspeed error)
Cause : This error occurs in such cases as the speed
exceeded the tracing acceleration speed limit in the
drop by the brake release at the power cutoff of the
absolute type vertical axis. (This condition should
not occur in normal conditions of use. Take
sufficient note on forced brake release.)
Treatment : If the error is occurred, it is necessary to absolute
reset.
0F0 Driver logic error Cause : Exceeded load, parameter (motor type)
mismatched, noise, malfunction of controller, etc.
Treatment : Please contact IAI.
0F2 Field bus module error Cause : A Field bus Module error was detected.
Treatment : Check the Field bus related parameters.
0F3 Field bus module not
detected
Cause : Field bus module not detected.
Treatment : If the error cannot be resolved even after putting the
power on again, please contact us.
0F4 Mismatched PCB This controller uses a different print circuit board depending on
the motor capacity.
The PCB is not applicable for the connected motor in the startup
check.
Cause : The actuator may not match the controller. Check
the model.
Treatment : Should this error occur, please contact IAI.
0F5 Nonvolatile memory write
verify error
It is verified at the data writing process to the non-volatile
memory that the data inside the memory and the data to be
written are matched. There was a mismatch detected in this
process.
Cause : Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
0F6
Cold start
Nonvolatile memory write
timeout
There is no response in the specified time duration during the
data writing to the non-volatile memory.
Cause : Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
