Error and System Messages
Appendix B
B-11
Message Description
DEPTH PROBE TRAVEL LIMIT The adaptive depth probe has moved to its AMPed travel limit. Note the value entered in AMP
is the adaptive depth probe deflection from the PAL determined probe zero point. It may not be
the actual total probe deflection.
DEPTH PROBE NOT SUPPORTED A depth probe axis has been AMPed on an axis located on a servo card or a 9/230 that does
not support the adaptive depth feature. (analog servo rev < rev 0.10 or 3 axis 9/260 9/290
digital servo cards)
DESKEW OPTION NOT INSTALLED If the AMPed name specifying the deskew slave servo is not zero, or the AMPed name
specifying the deskew master servo is not zero, and the option flag for deskew is zero, then the
system is held in E-Stop.
DEVICE ALREADY OPENED An attempt was made to open a device for download or upload from ports A or B when the
device was already opened.
DEVICE NOT OPENED YET The ready signal was not received when attempting to send data to or communicate with a
peripheral device connected to communication ports A or B.
DIAMETER AXIS MISCONFIGURED An invalid axis has been configured as the diameter axis.
DIRECTORY CHANGED TO MAIN DIRECTORY When a password is entered that does not have access to the protectable part program
directory and the protectable part program directory is currently selected, the control changes
the selected directory to the main directory.
DISP SELECT NOT ALLOWED You can not use the display select functions while the online PAL search monitor utility is active.
Leave the search monitor utility before you try to select a display.
DIVIDE BY ZERO ERROR A system software error has occurred. Consult Allen-Bradley customer support services.
(DO) NUMBER ALREADY USED When executing a program, an attempt was made to activate a DO loop that has the same loop
identifier (DO 1, 2, or 3) as an already active loop in the program. Provided they are not nested
loops, the same loop identifier can be used more than once in a program .
(DO) RANGES INTERSECT DO loops are improperly nested. A DO loop that is nested within another DO loop does not
have an END command before the original DO loop END occurs.
DRESS CANCEL DEFERRED TO G40 The in--process dresser cannot be canceled (made inactive) while dresser/wheel radius
compensation is active. If an attempt to cancel the in--process dresser is made, the control will
postpone the request until dresser/wheel radius compensation is canceled with a G40 (note that
M02, M30, and M99 can also cancel compensation).
DRESSER AXIS NOT ALLOWED An attempt was made to program the dresser axis when the over the wheel dresser feature has
been activated through PAL. You cannot program the dresser axis when the over the wheel
dresser feature is active.
DRESSER FLANGE LIMIT REACHED While dressing the grinding wheel the wheel size reached the entered flange limit. You should
stop dressing the wheel before damage to the wheel flange occurs.
DRESSER MINIMUM LIMIT REACHED The current dressing operation would dress the grinding wheel below the minimum wheel
diameter as specified on the dresser status screen. This dressing operation will not be
performed.
DRESSER MISCONFIGURED One of the AMP parameters for the dresser axis has not been configured properly. Either the
dresser axis, the vertical axis, or some other axis name is not a valid axis in the system. You
must re-configure your AMP. Refer to your AMP manual for details.
DRESSER MIS-POSITIONED Wheel re-enable was requested with IPD active and wheel is more than 4 inch-programming
counts (hard-code amount) away from its previously active absolute position. Wheel dressing
does not start.
DRESSER NOT INITIALIZED This error is generated if an attempt is made to activate the in--process dresser before the
dresser has been initialized through a wheel calibration operation.
DRESSER NOT/MIS CONFIGURED The grinder over-the-wheel dresser feature issues this message when a wheel is initialized and
the dresser parameters in AMP have been misconfigured. This message is issued when the
dresser axis, dresser vertical axis, or dresser other axis has not been selected, or has been
AMPed to have common axes, or has been AMPed to be a non-existent axis name.
