SD10 Self-diagnostic error
code
Self-diagnostic error code 1 The maximum of 16 types of error codes are stored into SD10 onwards
when the diagnostics detects an error.
(The same error code as one already stored in SD10 onwards is not
stored). The 17th error code onwards are not stored. Also error codes
are not stored when 16 types of error codes have already been stored
into SD10 to SD25.

SD53 AC/DC DOWN
detection
Number of times for AC/DC
DOWN detection
• Every time the input voltage fails to or below (85[%] AC power/65[%]
DC power) the rating during calculation of the Motion CPU module, the
value is incremented by 1 and stored in BIN code.
• The counter repeats a 0 to 65535 to 0 pattern.
SD61 I/O module verify
error module number
I/O module verify error
module number
The lowest I/O number of the module which has an error detected by the
I/O module verification is stored.
