Code
Alarm
Level
Alarm Name Cause/Treatment
0E6 Encoder count error Cause : This error code appears when the encoder cannot
detect the position information properly.
1) The encoder relay cable or supplied actuator
cable is disconnected or its connector is not
plugged in correctly.
2) Foreign matter is deposited on the code wheel.
3) The position relationship between the code
wheel and photo sensor changed due to shaft
center shift caused by application of excessive
external force, etc.
4) Faulty encoder board component
Treatment : 1) Check if any wire breakage on a connector and
the condition of wire connections.
For the case of 2), 3) or 4), it is necessary either to
clean the code wheel, adjust the installation
position, replace the motor unit or replace the
actuator. In any case, please contact IAI.
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
Cold start
Driver logic error Cause : Exceeded load, parameter (motor type)
mismatched, noise, malfunction of controller, etc.
Treatment : Please contact IAI.
0F1
Operation
release
Field bus link error Cause : This error occurs when the link of the fieldbus is
disconnected in a fieldbus type controller.
Treatment : It can be considered that there is a setting error in a
fieldbus related parameter, setting error in the
master, connection error in fieldbus cable or
interruption by noise.
0F2
Cold start
Field bus module error Cause : A Field bus Module error was detected.
Treatment : Check the Field bus related parameters.
