APPENDIX 2 Error Codes Stored Using The Motion CPU

The following errors are detected in the Motion CPU.
• Servo program setting error
• Positioning error
• Control mode switching error
• Motion SFC error
• Motion SFC parameter error
• Multiple CPU related error
(1) Servo program setting errors
These are positioning data errors set in the servo program, and it checks at the
start of the each servo program.
They are errors that occur when the positioning data is set indirectly.
The operations at the error occurrence are shown below.
• The servo program setting error flag (M9079) turns on.
• The erroneous servo program is stored in the error program No. storage
register (D9189).
• The error code is stored in the error item information register (D9190).
(2) Positioning error
(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
2) Major errors...... These errors occur in the external input signals or
3) Servo errors ......These errors detected in the servo amplifier or servo

SFC)" for details.
program, and the error codes (drive module : 1 to 999,
output module : 4000 to 9990) are used.
Check the error code, and remove the error cause by
correcting the Motion SFC program or servo program.
control commands from the Motion SFC program, and
the error codes (drive module : 1 to 1999, output
module : 10000 to 11990) are used.
Check the error code, and remove the error cause of
the external input signal state or Motion SFC program.
amplifier power supply, and the error codes 2000 to
2999 are used.
Check the error code, and remove the error cause of
the servo amplifier side.
