Message Description
AXIS INVALID FORG24/G25 Theprogrammed axiswas not AMPedfor software velocityloop operation, andcan not beused
in a G24 or G25 block. To usethese featuresthe axisprogrammed must beconfigured for
tachless operation(or be a digital servo).
AXIS ISHARD STOPPED, CANT ADJUSTSERVO Thetorque limit of theservo cannot be adjustedbecause, either theaxis is ina hard--stopped
state, or someother axis onthe sameservo cardis ina hard--stopped state.
AXIS MODULEPOWER FAULT Thecurrent through thepower output transistors ismonitored. If the current exceedsa fixed
level (greater than300% of controller rating)this fault willappear. Typical causes area shorted
lead, motor malfunction, or malfunctioningpower IGBTs.
AXIS MODULEOVER CURRENT One of the axis modulesof your 1394drive hasbeen requestedto providetoo muchcurrent.
This istypically causedby Accel/Decelcommand from theCNC isrequiring peakcurrent for an
excessive amount of time, the machine friction or inertial/viscousload isexcessive, the motor
has beenimproperly sized, ashort circuit exists acrossthe driveoutput terminals, logic supply
circuits havemalfunctioned, or AC input isincorrectly wired.
AXIS MODULEBUSS VOLTAGE LOSS TheDC bussupply waslost to theaxis module. Check slider connections/terminationstrip or
there could be a blownlink fuse.
AXIS MODULEOVER TEMP The1394 containsa thermalsensor which senses the internalambient temperature. Causes
could be: that the cabinet ambient temperature is above rating. The machine duty cycle
requires anRMS current exceedingthe continuousrating of thecontroller. The airflowaccess to
the 1394 is limitedor blocked. This does not necessarilyindicate a motor over temperature.
Motor over temperturesensors shouldbe wireddirectly intothe E-Stopstring.
AXIS MOVERCONFLICT WITHG16.3/G16.4 You have requested aPAL axismover function onan angledwheel grinder. You cannot use the
PAL axis moverin one of the angled wheel modesunless thePAL axismover hascontrol of
both the axial andthe wheelaxes.
AXIS NAMEDUPLICATE Two or moreaxes havebeen assignedthe samename inAMP.
AXIS NOTIN PROCESS You attempted to read/write aparamacro parameter for anaxis that isnot currently inthe
process requestingthe data. To access paramacro parameterdata for an axis, that axismust
be in the process making therequest.
AXIS POSITIONINCORRECT Using themid-start program function, you havesearched to a block that does not createthe
programmed contour if started from your current axisposition. Be aware the mid-start operation
may havesearched thrua offset operation that is not readilyapparent to determine your axis
position. The mid-start operationis aborted. You must re-perform themid-start operation and
either positionthe axesto thecorrect axis position, or usethe {MOVE& EXIT} softkeyto findthe
correct axis position.
AXIS SELECTNOT ALLOWED The{AXIS SELECT} softkeywas pressedwhen noaxis select optionis available. Axis select is
only availableon largescreens andnormal character sizescreen forsystems that containmore
then 9 axes totalor dual processsystems withmore than8 axesin a process. It is not available
when the small screen(showing allsystem AMPedaxes) is beingviewed.
AXIS TYPE-POSITIONLOOP ERROR In patch AMP, an axiswas assigned a positionloop typethat is illegal forthe axistype assigned
to that axis.

BACKUP VERSIONOF AMPWASCOPIED TO RAM The AMPin RAMwas erased(battery backupfailed) or corrupted, sothe controlautomatically
copied the version of AMP in backupmemory intoRAM memory. (The control storesAMP in
backup, but works fromthe copyof AMP inRAM memory.)
BAD DACMONITORPATCH AMPENTRY An invalidvalue wasentered intopatch AMP parameter #86 or#87. Either parameter allows
the axes to bemonitored throughthe servo module (DAC) analog output. See documentation
provided by Allen-Bradley onpatch AMP, or contact Allen-Bradley customersupport service.
BAD FIRSTPOCKET BLOCK Whenperforming anirregular pocket cycle, the first pocket blockshould be away fromthe
pocket start/end corner, not towardit. The moveto thestart/end corner isgenerated basedon
the coordinates programmed inthe pocket definition block itself.
BAD PAL PROM Oneof the PAL PROM chips (pluggedinto themain processor board) hasfailed oris not
plugged in properly.
