Error and System Messages
Appendix B
B-5
Message Description
BAD RAM DISC SECTOR CHECKSUM ERROR A RAM disk sector error was detected during the RAM checksum test at power-up. Attempt to
power-up again. If the error remains, contact Allen-Bradley customer support services.
BAD RECORD IN PROGRAM This indicates a serious problem with the program. Attempt to open the program a second time.
If retry doesn’t work, you may have to delete the program. Typically this error is not caused by a
programmer or operator action. It is typically caused by an internal software error in the
program.
BAD STATE/TOKEN COMBINATION (PROGRAM
ERROR) While attempting to decode the current block, a combination of characters caused a decode
error to occur. Check the characters in the current block for an illegal combination.
BATTERY FAILURE The battery that provides backup of the RAM memory is not functioning; the voltage may be low.
The battery may be dead, removed, or poorly connected.
BLK DELETE CHG IGNORED ON PREPARED BLKS A block-delete was activated while a program was executing. This change is ignored by the
control for blocks that have already been read into the control’s set-up buffer (see block
look-ahead in user’s manual).
BLOCK LENGTH ERROR A block that exceeds the allowable maximum block length was programmed.
BLOCK RETRACE ABORTED The block retrace operation being performed has been canceled. When <CYCLE START> is
pressed, the control will return the tool along a linear path back to the start-point of the block
retrace operation.
BOOT DIRECTORY IS MISSING The update utility failed to properly create the system boot directory. Retry the update. If the
error occurs again, contact your local Allen Bradley service.
BOOTSTRAP FAILED TO START The bootstrap code did not send the “ok”signal to the main processor within the specified time.
BOTH AXES IN QPP PLANE NOT PRGMD The second block of a currently executing QuickPath Plus two-block set does not contain both
required axis words in the current plane. Both axis words are required to correctly identify the
end-point of the second move.
BOTH LINES ARE PARALLEL Both blocks of a two-block QPP sequence are parallel, and no mathematical intersection can be
computed.
BOTH PORTS ARE BUSY An attempt was made to use or monitor communication ports A or B when neither were
available.
BUSY, REQUEST IGNORED You have requested an operation while the control is currently executing some other higher
priority function. The control must first complete the higher priority task before your new task
can be performed.
C
CALLED 7300 PATTERN NAME IS BAD The 7300 pattern name that is called by a part program does not exist .
CANCEL/REMOVE OFFSET BEFORE AXIS CHANGE You have attempted to change the active tool length axis while an length offset is currently
active on that axis. You must cancel tool length offsets before you are allowed to change the
active tool length axis.
CANNOT (GOTO) TO INSIDE A (DO) A (GOTO) command cannot transfer execution to a block which is located within a (DO) loop.
CANNOT ACCESS REMOTE VARIABLE Variable name is invalid. Check the fields for CNC name and remote name, and make sure they
are in the correct format.
CANNOT ACTIVATE - OPEN PROGRAM An attempt was made to activate a program for execution when it was still open for an editing
operation. Before it can be activated for automatic execution, it is necessary to press the {EXIT
EDITOR} softkey from the edit menu to close a program being edited.
CANNOT ACTIVATE RAM PARTITION The RAM disk has been corrupted. Attempt to perform a “REFORMAT”operation. If this is
unsuccessful, consult Allen-Bradley customer support services.
CANNOT ASSIGN IN CURRENT MODE An attempt was made to modify a paramacro parameter that cannot be modified when the cutter
compensation or TTRC feature is active.
CANNOT CALCULATE - PROMPT PRESENT An attempt to perform a calculate operation was made when some other prompt was present on
line 2 of the CRT. Before the control will allow a calculation to be made, it is necessary to
remove any prompts from line 2 .
