Error and System Messages
Appendix B
B-13
Message Description
ENCODER QUADRATURE FAULT An error has been detected in the encoder feedback signals. Likely causes are excessive noise,
inadequate shielding, poor grounding, or encoder hardware failure.
END OF FILE When transferring a file over the serial port, the control has reached the last block in the
program.
END OF PROGRAM When displaying a part program on the CRT, the control has reached the last block in the
program.
END OF PROGRAM REACHED When performing one of the program search features, the control has reached the last block in
the program.
ENTER ALL REQUIRED PROMPT DATA An attempt was made to create a transfer line part program from the quick view screen without
entering all the required quick view screen prompt data. Optional data is shown in reverse
video.
ENTRY OUT OF RANGE A parameter value was entered that is larger or smaller than the usable range determined in
AMP or allowed on the system.
ERASE PROMPT The operator has data on the input line (line 2 of the CRT) that must be cleared or entered so
that a new prompt can be displayed on the input line.
ERROR ACCESSING PROGRAM A major software error was generated by the control’s internal software when editing the
program; the program should be deleted. If the error persists, contact Allen-Bradley customer
service support.
ERROR FOUND A QuickCheck syntax check operation has found an error in the currently displayed program
block. This is the block after the block containing the block-completed symbol “@”. Press
<CYCLE START> to continue the program check.
ERROR IN CIRCLE DATA This error can occur when digitizing a circular block, typically the result of entering positions that
cannot be correctly connected with an arc.
ERROR LOOKING FOR (END) COMMAND The control has found a paramacro END command that does not match one of the active
paramacro DO loop ranges.
ERROR TRANSFERRING PAL TO CPU #2 An error occurred while PAL was being transferred to the I/O CPU at power-up. PAL is
transferred to the I/O CPU at power-up on a 9/290. Consult Allen-Bradley customer support
services.
EXACTLY 2 DIGITS MUST FOLLOW DECIMAL PT You have used incorrect search string syntax in the PAL search monitor utility.
EXCESS FOLLOWING ERROR The following error for an axis exceeds the allowable value as defined in AMP. Most likely
cause is AMP servo related parameters are set too stringently for the hardware. Also caused by
axis runaway.
EXCESS SKEW ON The calculated skew is larger than the AMPed maximum allowable skew.
EXEC BOOTSTRAP FAILED The bootstraper failed to respond within the specified time for any code segment. Consult
Allen-Bradley customer support services.
EXPRESSION INCOMPLETE A syntax problem has been found in a paramacro expression. The control is unable to correctly
evaluate the expression as entered.
EXTRA DATA IN INTERRUPT MACRO BLK An attempt was made to program extra data (such as a G-code) in the M-code block that
activates or deactivates an interrupt program. No extra commands can be programmed in this
block.
EXTRA DATA IN QPP BLOCK The QuickPath Plus block has been programmed with too many parameters. For example, you
cannot program a G13 block with both axis data and an angle word or with an L or A word in the
block.
EXTRA I/O RING DEVICE An I/O device that has not been defined in the I/O assignment file is physically present on the
I/O ring.
