Diagnostic error
code
• Error codes for errors found by diagnosis are stored as BIN data.
• Refer to "APPENDIX 3" for details of the error code.
• After confirm the error content, except the stop error, it is possible to clear by
ON to OFF of the Motion error detection flag (M2039).
• Clear SD0 to SD26 by ON to OFF of the Motion error detection flag (M2039)
for except the stop error after confirming the error content.
SD1
• The year (last two digits) and month that SD0 data was updated is stored as
BCD 2-digit code.
Example : January 2006
H0601 B15 B7 B0 B8 to to
Month(1 to 12) Year(0 to 99)
SD2
• The day and hour that SD0 data was updated is stored as BCD 2-digit code.
