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.
Alarm details : 44h
In this case, the alarm detailed information of Linear encoder error 1(2A) is "44". This numeral is indicated in
hexadecimal number. Convert "44" of hexadecimal number to a binary-coded form as shown below.
