Message Description
ENCODERQUADRATUREFAULT Anerrorhas been detected in the encoder feedbacksignals. Likelycausesare excessivenoise,
inadequateshielding, poorgrounding,or encoderhardwarefailure.
END OF FILE When transferri ng a file overtheserial port,thecontrolhasreached thelastblockinthe
program.
END OF PROGRAM Whendisplaying a partprogram on theCRT,the control hasreached thelastblock in the
program.
END OF PROGRAM REACHED Whenperformingone of theprogramsearchfeatures,thecontrol has reached thelast blocki n
theprogram.
ENTER ALL REQUIRED PROMPT DATA Anattemptwas madetocreatea transferline partprogramfromthe quickview screenwithout
enteringall the requiredquickview screenpromptdata. Optionaldatais shown in reverse
video.
ENTRYOUT OF RANGE A parametervalue wasenteredthatis larger orsmallerthantheusable range determined in
AMP or allowed on the system.
ERASE PROMPT The operator hasdataon the inputline (line 2 of theCRT ) thatmustbe cleared or enteredso
thata new promptcan be displayedontheinput line.
ERROR ACCESSING PROGRAM Amajor software errorwasgenerated by thecontrol’s internal software when editing the
program;theprogram shouldbedeleted. Iftheerrorpersists, contactAllen-Bradleycustomer
service support.
ERROR FOUND AQuickChecksyntaxcheck operationhas foundanerrorin the currently displayed program
block. This istheblock after the blockcontaining theblock-completed symbol“@”. Press
<CYCLESTART> tocontinue theprogram check.
ERROR INCIRCLE DATA T his errorcanoccur when digitizinga circularblock,typicallythe resultof enteringpositionsthat
cannotbe correctly connectedwith an arc.
ERROR LOOKING FOR (END) COMMAND T he control hasfounda paramacroEND commandthatdoes not match one ofthe active
paramacro DO loop ranges.
ERROR TRANSFERRINGPAL TO CPU #2 An erroroccurredwhile PAL was being transferred tothe I/OCPUat power-up. PALis
transferred tothe I/OCPU at power-upon a9/290. ConsultAllen-Bradleycustomersupport
services.

EXCESS FOLLOWING ERROR Thefollowingerrorforan axis exceedstheallowablevalueas defined in AMP. Mostlikely
causeis AMPservo related parameters are settoo stringently for thehardware. Alsocaused by
axisrunaway.
EXCESS SKEW ON Thecalculated skew islargerthan theAMPedmaxi mum allowable skew.
