Message Description
ENCODER QUADRATURE FAULT Anerror has beendetected inthe encoderfeedback signals. Likely causesare excessivenoise,
inadequate shielding, poor grounding, or encoder hardware failure.
END OFFILE When transferringa fileover the serialport, the controlhas reachedthe last blockin the
program.
END OFPROGRAM When displayinga part programon theCRT, the control hasreached thelast block inthe
program.
END OFPROGRAM REACHED Whenperforming oneof the program searchfeatures, the controlhas reachedthe last blockin
the program.
ENTER ALLREQUIRED PROMPTDATA Anattempt was madeto createa transferline part programfrom thequick view screenwithout
entering all the requiredquick viewscreen prompt data. Optional datais shownin reverse
video.
ENTRYOUT OF RANGE A parameter value was entered that is larger or smaller thanthe usablerange determinedin
AMP or allowedon thesystem.
ERASE PROMPT Theoperator has dataon theinput line (line2 of theCRT)that must be clearedor enteredso
that a new prompt can bedisplayed onthe input line.
ERROR ACCESSINGPROGRAM A major softwareerror was generatedby thecontrol’sinternal softwarewhen editingthe
program; the program should bedeleted. If the error persists, contact Allen-Bradleycustomer
service support.
ERROR FOUND A QuickChecksyntax checkoperation hasfound anerror in thecurrently displayedprogram
block. This is theblock after theblock containingthe block-completedsymbol “@”. Press
<CYCLE START>to continuethe program check.
ERROR INCIRCLE DATA This error canoccur when digitizinga circularblock, typically theresult of entering positionsthat
cannot be correctly connected withan arc.
ERROR LOOKINGFOR (END) COMMAND The controlhas founda paramacroEND commandthat does not matchone of theactive
paramacro DO loop ranges.
ERROR TRANSFERRINGPAL TO CPU #2 Anerror occurred whilePAL wasbeing transferredto theI/O CPUat power-up. PAL is
transferred to the I/O CPU at power-upon a9/290. Consult Allen-Bradley customer support
services.
EXACTLY 2 DIGITSMUST FOLLOWDECIMAL PT You have used incorrect search stringsyntax in the PAL searchmonitor utility.
EXCESS FOLLOWINGERROR The followingerror for anaxis exceeds theallowable valueas definedin AMP. Most likely
cause is AMP servorelated parametersare set toostringently for thehardware. Also causedby
axis runaway.
EXCESS SKEWON The calculatedskew islarger than theAMPed maximum allowable skew.
EXEC BOOTSTRAPFAILED The bootstraper failed torespond withinthe specifiedtime for anycode segment. Consult
Allen-Bradley customersupport services.
EXPRESSION INCOMPLETE A syntax problemhas beenfound ina paramacroexpression. The control isunable tocorrectly
evaluate the expression as entered.
EXTRA DATA ININTERRUPT MACROBLK Anattempt was madeto program extradata (suchas aG-code) in the M-code block that
activates ordeactivates aninterrupt program. No extracommands canbe programmedin this
block.
EXTRA DATA INQPP BLOCK TheQuickPath Plusblock hasbeen programmedwith toomany parameters. For example, you
cannot program aG13 blockwith bothaxis dataand anangle wordor with anL orA wordin the
block.
EXTRA I/ORING DEVICE An I/Odevice that has not been defined inthe I/Oassignment file isphysically present onthe
I/O ring.
