Error Reporting
GFK-1742A Appendix A Error Reporting A-9
A
95
Status Only Local Logic Add/Subtract Overflow Warning Module The Local Logic program added or subtracted numbers that
caused an overflow condition to occur. The allowable range is
–2,147,483,648 to +2,147,483,647. Change the local logic
program to prevent overflow or set the Overflow variable to 0
at the end of each local logic cycle.
96
Status Only Local Logic Absolute(ABS) Overflow warning Module The Local Logic program attempted to perform an ABS
operation on –2,147,483,648 resulting in an overflow.
97
Status Only Local Logic Timeout Warning Module The Local Logic program execution time is close (greater than
275 Microseconds) to the maximum allowable execution time
(300 Microseconds). Decrease the Local Logic execution time
by reducing the number of Local Logic statements or by
modifying the program structure. Consult Appendix E for
more information on local logic execution time.
98
Status Only Local Logic Execute on First Sweep Error Module The user attempted to execute Local Logic on the first PLC
sweep (e.g. if the Local Logic enable Q bit is on when the
PLC is switched from Stop to Run Mode).
99
Status Only Local Logic Invalid Program Name or Not Enabled
in Configuration
Module The Local Logic Program Name specified in Hardware
Configuration is not valid (or empty) or Local Logic is not
enabled in Hardware Configuration.
9A
Stop Fast Local Logic Stop Error (Per-Axis) Axis A Local Logic Stop Fast Error occurred (error codes 91-94).
Hardware Limit Switch Errors
A0
Stop Fast Limit Switch (+) error Axis The Positive Overtravel Limit Switch input is off. If
Overtravel Limit switches are not used, set the Overtravel
Limit Switch configuration to Disabled.
A1
Stop Fast Limit Switch (–) error Axis The Negative Overtravel Limit Switch input is off. If
Overtravel Limit switches are not used, set the Overtravel
Limit Switch configuration to Disabled.
Hardware Errors
A8
Stop Fast Out of Sync error Axis Position Error has exceeded the Position error limit. Possible
sources for this error are:
1. Position error limit being set too low for the application.
2. Feedback device being disconnected or slipping on
controlled device
3. Incorrect Feedback device wiring. (i.e. positive rotation
indicated as negative by feedback device)
A9
Status Only Loss of Position Feedback Axis A Quadrature Error has been detected on an incremental
quadrature encoder. Check the encoder wiring and ensure that
the encoder is not operated beyond its rated speed.
