Code Error Cause/action
0E7 Phase A/B/Z open Encoder signal cannot be detected properly.
Cause: [1] Open encoder extension cable or supplied actuator cable,
or poor connector contact
[2] Faulty encoder
Action: [1] Check the connector for possibility of open circuit, and
examine the connection condition.
(Perform a continuity check by referring to 2-5, “Supplied
Cables.”)
If the cable is normal, the encoder may be faulty. Please
contact IAI.
0F8 Corrupt nonvolatile memory Abnormal data was detected during the nonvolatile memory check at the
startup.
Cause: [1] Faulty nonvolatile memory
[2] The memory was written more than 100,000 times.
(As a rough guide, the nominal life of nonvolatile memory is
around 100,000 rewrites.)
Action: If the alarm occurs again after the power has been
reconnected, please contact IAI.
0F9 Abnormal expansion RAM Abnormal data was detected during the expansion RAM check at the
startup.
Cause: [1] Malfunction due to noise, etc.
[2] Faulty RAM
[3] Faulty circuit component around RAM
Action: Reconnect the power.
If the alarm occurs again, check for effect of noise.
If you have a spare controller, change to the spare controller. If
the alarm still occurs, noise is suspected.
If the cause cannot be specified, please contact IAI.
0FA Abnormal CPU The CPU is not operating properly.
Cause: [1] Malfunction due to noise, etc.
[2] Faulty CPU
[3] Faulty circuit component around CPU
Action: Reconnect the power.
If the alarm occurs again, check for effect of noise.
If you have a spare controller, change to the spare controller. If
the alarm still occurs, noise is suspected.
If the cause cannot be specified, please contact IAI.
0FB Abnormal FPGA The FPGA (gate array) is not operating properly in the absolute
controller.
Cause: [1] Malfunction due to noise, etc.
[2] Faulty FPGA
[3] Faulty circuit component around FPGA
[4] The board in the controller is not installed properly.
Action: Reconnect the power.
If the alarm occurs again, check for effect of noise.
If you have a spare controller, change to the spare controller. If
the alarm still occurs, noise is suspected.
If the cause cannot be specified, please contact IAI.
