13.7.4 Detailed explanation of linear encoder error 1 (2A. )
If the cause of Linear encoder error 1 (2A. ) occurrence is not identified, confirm the details shown on the
following table according to the alarm detailed information for the alarm history display of MR Configurator, and
then contact with the linear encoder manufacturer.

As an example, the following describes the detailed information when Linear encoder error 1(2A. ) occurs in
the linear encoder AT343A manufactured by Mitutoyo Corporation.
The value is displayed in
hexadecimal. Convert it
to decimal to read.
3
In this case, the alarm detail of the linear encoder error (2A. ) is "3".
An alarm detail is displayed in hexadecimal (h) in MR Configurator, but it is displayed in decimal in MR-J3W-B.
In this example, confirm items with number "3" in the Detail column. The occurrence of the Photoelectric error is
identified.
