Error and System Messages
Appendix B
B-15
Message Description
FLASH SIMMS CONTAIN INVALID DATA Flash SIMMs have become corrupted probably from a communication error during a system
update. Retry the system executive update utility. If the situation persists, contact
Allen--Bradley support.
FLASH SIMMS U10 AND U14 ARE EMPTY OR
MISSING Make sure your flash SIMMs are installed in the correct tracks. Refer to the 9/Series integration
and maintenance manual section covering your processor for details on flash installation.
Remove and reseat flash SIMMs.
FLASH SIMM U10 IS EMPTY OR MISSING Make sure your flash SIMMs are installed in the correct tracks. If they appear to be installed
correctly, remove and reseat SIMMs. If problem persists, contact Allen--Bradley support service.
FLASH SIMM U14 IS EMPTY OR MISSING Make sure your flash SIMMs are installed in the correct tracks. If they appear to be installed
correctly, remove and reseat SIMMs. If problem persists, contact Allen--Bradley support service.
FLASH WRITE ERROR A problem occurred while writing to flash, for example bad flash, no flash, or no voltage.
FOREGROUND OVERLAP The foreground tasks did not complete execution within the 20-millisecond period allocated.
Foreground tasks include PAL foreground, axis interpolation, servo interface, and I/O ring
scanning. Correct by reducing PAL foreground program size or removing some devices from
the I/O ring.
G
G10 NOT ALLOWED DURING CYCLE G10 code is not allowed to be used during the cycle. Cancel the fixed cycle.
G24 NOT ALLOWED G24 is not allowed when any automatic G coded cycle is active (such as G81).
G24 PLANE INCOMPATIBILITY The hard stop axis may not be in the active part rotation plane.
G25 NOT ALLOWED G25 is not allowed when any automatic G coded cycle is active (such as G81).
G25 PLANE INCOMPATIBILITY The adaptive feed axis may not be in the active part rotation plane.
G26 NOT ALLOWED G26 (adaptive depth probe) can not be programmed when another modal group is active (such
as a G81 fixed cycle).
G26 PLANE INCOMPATIBILITY A conflict between a plane dependent feature and a G26 (depth probe). For example if part
rotation is active and a G26 is programmed on an axis in the part rotation plane this error is
generated. Refer to the 9/Series users manual section on G26 for details on incompatible
planar features.
G28 BLOCK DOES NOT PRECEDE G29 BLOCK A G29 block was programmed before a G28 block. During 7300 tape compatibility mode, the
first automatic threading block must contain a G28 code; the next block must contain a G29
code.
G29 BLOCK DOES NOT FOLLOW G28 BLOCK A G28 block was programmed without a following G29 block. During 7300 tape compatibility
mode, the first automatic threading block must contain a G28 code; the next block must contain
a G29 code.
G40 NOT ALLOWED IN CIRCULAR An exit move from cutter compensation or TTRC was attempted in a circular block (G02 or G03).
An exit move (programmed with a G40) must generate a linear move.
G53 NOT ALLOWED IN G91 MODE An attempt was made to make an incremental move in the machine (absolute) coordinate
system. Only absolute moves (G90) are permitted in the machine coordinate system.
G53 NOT ALLOWED IN INCREMENTAL MODE A G53 move to absolute position was requested while in incremental mode.
G53 ON AN UNHOMED AXES An attempt to program a move in the machine (absolute) coordinate system was made before
the axis was homed. It is necessary to home the axes to establish the location of the machine
coordinate system.
G91 MODE NOT ALLOWED IN QPP Since QuickPath Plus is generally used to program blocks without knowing the intersection of
the blocks, it is impossible to calculate a location for the end-point of the block when the move is
incremental. QuickPath Plus must be programmed in absolute mode (G90).
(G-CODE) TABLE ERROR There has been an internal software fault relative to the G-code table. Consult Allen-Bradley
Customer Support Services.
(GOTO) SEQ. NUMBER NOT FOUND The sequence number (N word) called by a GOTO command does not exist in the currently
executing program.
