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 battery alarm output BALM and
replace the battery if it is ON (OFF for Remote
I/O Mode).
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.
0F4
Mismatched PCB
This controller uses a different print circuit board depending on
the motor capacity.
Mismatch of connected motor and the PCB is detected 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
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.
0F8
Nonvolatile memory
data destroyed
Abnormal data was detected during the nonvolatile memory
check after starting.
Cause
: Faulty nonvolatile memory.
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
0FA
Cold start
CPU error
The CPU operation is not normal.
Cause
: 1) Faulty CPU
2) Malfunction due to noise
Treatment : When the error is caused even when the power is
re-input, please contact IAI.
