Message Description
UNABLE TO SYNCHIN CURRENTMODE The control can not performthe request tosynchronize spindles. Possible causesare:
synchronization is already active; virtual/cylindricalprogramming ora threadingoperation is
active on the primary or follower spindlewhen thesynchronization request ismade; or on a
dual--process system, oneof the requestingprocesses cannot gaincontrol over bothspindles.
UNABLE TO WRITETOFLASH MEMORY If flash SIMMsappear to beinstalled correctly, removeand reseat SIMMs. If problem persists,
contact Allen--Bradley support service.
UNDEFINED INTERRUPTMACRO/SUBPROG An interrupt program request was received by the control, but it cannot find the paramacro or
sub-program withthe correspondingprogram name inthe programdirectory. The program
name is defined inthe enableblock (M96)with aP-word.
UNEXPECTED DEPTHPROBE TRIP G26 adaptivedepth probehas firedunexpectedly. Either it has firedin anon-G26 blockor it has
fired before the programmed G26contact range.
UNSPECIFIED NETWORKERROR An erroris beingsent from another devicethat the modulecannot interpret.
UNUSABLE WORDSIN ZONE BLOCK Anaxis wordor other data was programmed ina programmable zone block (G22, G22.1 G23,
G23.1). These G-codes must beprogrammed in blocks containingno other data except ablock
delete /, N word, or comments.
UNRECOVERABLE ERROR Can occur whenupdating flash SIMMs withnew 9/Seriesfirmware. Retry theupdate utility. If
problem persists, callAllen-Bradley Support Services.

VEL LOOP INVALID WITHDAC OUT An attempt wasmade toselect the position/velocityservo looptype ona 9/440HRsystem.
VIRTUALAXIS NOTALLOWED Thevirtual axiscan onlybe programmedwhen thecontrol isin avirtual axismode. You must
place the control inG16.3 modeto programa virtual axis.
VIRTUALC NEEDSSPINDLE WITHFDBK Whenthe spindleis thevirtual C axisin avirtual Capplication, it must be configuredto provide
feedback tothe servomodule.
VIRTUAL/REALAXIS NAMECONFLICT Theaxis configuredin AMPas theVirtualC axis waspreviously configuredas alinear machine
axis.

WARNING- G10OFFSETS ALTERED This messagewarns that theoffsetswere changedby aG10 blockduring executionfrom a
mid-program start.
WARNING- PROGRAM STARTINGAT BEGINNING An activeprogram was editedand thenthe editor exited. This causesthe activeprogram to
restart at the beginning of the program.
WARNING- VERIFY MODALCODES The MIDSTARTPROGRAM featurethat activates modal codesfor mid-program executionis
requesting that these generated modal codes bechecked beforeprogram execution is started.
These modal codes canbe checkedon theG- and M-code status screens.
WARNING -- WATCHDOG JUMPER ISINSTALLED Thiserror indicates that thewatchdog hasbeen bypassedon the9/Series hardwareand your
system willnot report watchdog errors. Call Allen-Bradleyfield service.
WHEEL AXIS MOTION INVALID IN G16.3/G16.4 While inthe angledwheel grindingmode youhave attemptedto program thewheel axisdirectly.
Only thevirtual axisand theaxial axiscan beprogrammed inangled wheelmode.
WILDCARD MUSTBE AT START/ENDOF SYMBOL You haveused incorrect searchstring syntaxin thePAL searchmonitor utility.
WORK CO-ORDCHANGES NOT ALLOWED You have attempted tomake achange tothe workcoordinate system at aninvalid time.
Changes tothe workcoordinate systemcan not be performed when somefeatures are active.
Disable the offending featurebefore attemptingto changecoordinate systems.
