Message Description
FLASH SIMMSCONTAIN INVALID DATA Flash SIMMshave becomecorrupted probablyfrom acommunication error duringa system
update. Retry the systemexecutive update utility. If the situationpersists, contact
Allen--Bradley support.
FLASH SIMMSU10 ANDU14 AREEMPTY OR
MISSING
Make sure your flashSIMMs areinstalled inthe correct tracks. Refer tothe 9/Seriesintegration
and maintenance manual sectioncovering yourprocessor for detailson flashinstallation.
Remove and reseat flash SIMMs.
FLASH SIMMU10 ISEMPTY ORMISSING Makesure your flashSIMMs areinstalled inthe correct tracks. If they appear tobe installed
correctly, remove and reseat SIMMs. If problem persists, contact Allen--Bradley support service.
FLASH SIMMU14 ISEMPTY ORMISSING Makesure your flashSIMMs areinstalled inthe correct tracks. If theyappear to be installed
correctly, remove and reseat SIMMs. If problem persists, contact Allen--Bradley support service.
FLASH WRITEERROR A problem occurredwhile writingto flash, forexample bad flash, no flash, or no voltage.
FOREGROUND OVERLAP Theforeground tasksdid not completeexecution withinthe 20-millisecond period allocated.
Foreground tasks include PAL foreground, axis interpolation, servo interface, andI/O ring
scanning. Correct by reducing PAL foreground program sizeor removing somedevices from
the I/O ring.
G
G10 NOT ALLOWEDDURING CYCLE G10 codeis not allowed to beused duringthe cycle. Cancel thefixed cycle.
G24 NOT ALLOWED G24is not allowed when anyautomatic G coded cycle is active (such as G81).
G24 PLANE INCOMPATIBILITY The hardstop axismay not bein theactive part rotationplane.
G25 NOT ALLOWED G25is not allowed when anyautomatic G coded cycle is active (such as G81).
G25 PLANE INCOMPATIBILITY The adaptivefeed axismay not bein theactive part rotationplane.
G26 NOT ALLOWED G26(adaptive depthprobe) can not beprogrammed whenanother modal groupis active(such
as aG81 fixedcycle).
G26 PLANE INCOMPATIBILITY A conflict betweena planedependent feature anda G26(depth probe). For example if part
rotation is active anda G26is programmedon anaxis inthe part rotationplane thiserror is
generated. Refer to the9/Series usersmanual section on G26 for details onincompatible
planar features.
G28 BLOCK DOES NOT PRECEDE G29 BLOCK A G29block wasprogrammed beforea G28block. During 7300tape compatibilitymode, the
first automatic threadingblock must containa G28code; the next blockmust contain aG29
code.
G29 BLOCK DOES NOT FOLLOW G28 BLOCK A G28 blockwas programmedwithout a followingG29 block. During 7300tape compatibility
mode, the first automatic threading blockmust contain aG28 code; the next block must contain
a G29 code.
G40 NOT ALLOWEDIN CIRCULAR An exit movefrom cutter compensation orTTRC wasattempted ina circular block(G02 or G03).
An exit move (programmed with aG40) must generate alinear move.
G53 NOT ALLOWEDIN G91 MODE An attempt was made tomake an incremental movein themachine (absolute) coordinate
system. Only absolute moves(G90) arepermitted inthe machinecoordinate system.
G53 NOT ALLOWEDIN INCREMENTAL MODE A G53 moveto absoluteposition wasrequested while in incremental mode.
G53 ON AN UNHOMEDAXES An attempt toprogram a movein the machine (absolute) coordinate system wasmade before
the axis was homed. It is necessaryto homethe axesto establishthe locationof the machine
coordinate system.
G91 MODE NOT ALLOWEDIN QPP Since QuickPathPlus isgenerally usedto program blockswithout knowing theintersection of
the blocks, it is impossible tocalculate alocation for the end-point of theblock whenthe moveis
incremental. QuickPath Plus must beprogrammed in absolute mode (G90).
