0EA Phase-B
disconnection
detection
Encoder signals cannot be detected correctly.
Cause:
[1] Loose or disconnected encoder-relay cable connector
[2] Piano switch 4 on the simple absolute unit is not set correctly.
[3] If a RA10C actuator is used together with an actuator or actuators of
other type, the encoder cables may not be connected in the correct
combination.
Action:
[1] Check for loose or disconnected connector.
[2] Check if the settings conform to 5.1.1, “Piano Switch Settings” in the
operation manual for the simple absolute unit.
[3] Check the model name of the encoder cable.
(Encoder cable connecting the simple absolute unit and actuator)
Note) This action is applicable only to RCP2 series controllers.
Cable for RA10C type: CB-RFA-*Other actuators: CB-RCP2-*
0F4 Unmatched PCB This controller uses a different motor drive circuit depending on the motor
capacity, and thus adopts a different printed circuit board (PCB)
appropriate for each motor capacity.
For this reason, whether the motor type set by the applicable
manufacturer’s parameter matches the board is checked in the initialization
process after startup.
This error indicates that the two do not match.
Cause: The parameter was not entered correctly or the correct board was
not assembled.
Action: Should this error occur, please contact IAI.
0F8 Damaged nonvolatile
memory
Abnormal data was detected during the nonvolatile memory check after
starting.
Cause: [1] Faulty nonvolatile memory
[2] The memory has been rewritten more than 100,000 times.
(The nominal rewrite limit of the nonvolatile memory is around
100,000 times.)
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
0FA CPU error The CPU is not operating properly.
Cause: [1] Faulty CPU
[2] Malfunction due to noise
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
0FB FPGA error Malfunction occurred in the controller.
Cause: Faulty internal part of the controller (FPGA)
Malfunction due to noise
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
0FC Logic error Malfunction occurred in the controller.
Cause: Faulty internal part of the controller
Malfunction due to noise
Action: If the alarm generates again after reconnecting the power, please
contact IAI.
