APPENDIX 1 Error Codes Stored Using the Motion CPU

The servo program setting errors and positioning errors are detected in the Motion
CPU side.
(1) Servo program setting errors
(2) Positioning error
These are positioning data errors set in the servo program, and it checks at the
start of each servo program.
They are errors that occur when the positioning data is specified indirectly.
The operations at the error occurrence are shown below.
• The servo program setting error flag (SM516) turns on.
• The erroneous servo program is stored in the error program No. storage register
(SD516).
• The error code is stored in the error item information register (SD517).
(a) Positioning errors occurs at the positioning start or during positioning control.
There are minor errors, major errors and servo errors.
1) Minor errors...... These errors occur in the Motion SFC program or servo
program, and the error codes 1 to 999 are used.
Check the error code, and remove the error cause by
correcting the Motion SFC program or servo program.
2) Major errors...... These errors occur in the external input signals or
control commands from the Motion SFC program, and
the error codes 1000 to 1999 are used.
Check the error code, and remove the error cause of
the external input signal state or Motion SFC program.
3) Servo errors ..... These errors detected in the servo amplifier, and the
error codes 2000 to 2999 are used.
Check the error code, and remove the error cause of
the servo amplifier side.
