Code Error name Cause/Action

0EF Absolute encoder

error (3)

Cause:

The current value changed at a speed equal to or greater than the

specified rotational speed due to an external factor or for other reason

while the power was cut off.

Action:

Change the speed setting in the simple absolute unit and also implement

measures to prevent the actuator from moving at a speed equal to or

above the specified setting while the power is cut off.

If the battery backup time is more than sufficient, try setting a higher motor

speed.

See also: 5.1.1, “Piano Switch Settings” in the operation manual for the

simple absolute unit.

If this error occurred, perform an absolute reset by following the specified

procedure (5.2, “Absolute Reset Method”).

0F5 Nonvolatile memory

write verification error

When data has been written to the nonvolatile memory, the written data is

read again to check (verify) if it matches the original data.

This error indicates that the two data do not match.

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.

0F6 Nonvolatile memory

write timeout

This error indicates that response is not received within the specified time

after data was written to the nonvolatile memory.
