APPENDIX 1.3 Major errors

These errors occur by control command from the external input signal or Motion SFC program, and the error codes 1000 to 1999 are used.

Major errors include the positioning control start errors, positioning control errors, absolute position system errors and system errors.

(1) Positioning control start errors (1000 to 1099)

These errors are detected at the positioning control start.

The error codes, causes, processing and corrective actions are shown in Table

1.8.
