Error and System Messages
Appendix B
B-32
Message Description
OVER SPEED IN POCKET CYCLE The programmed feedrate for an irregular pocket cycle (G89) was too high for the cycle to keep
up. The part program stops at the endpoint of the block in which the error occurred. The cycle
must be executed with a lower feedrate.
OVERTRAVEL (+) The indicated axis has reached the positive software overtravel limit during an axis jog. This
message can appear prior to reaching the overtravel limit in certain instances. For example, if a
single pulse from the handwheel will result in a large incremental move beyond the overtravel
limit, this error message will appear before the axis moves up to the limit.
OVERTRAVEL (-) The indicated axis has reached the negative software overtravel limit during an axis jog. See
OVERTRAVEL (+) for details.
P
P VALUE OUT OF RANGE An attempt was made to call a macro or sub-program using a program number, following the
P-word, that is out of the valid range. Valid range for a P-word is 1 to 99999.
PAL & 9/SERIES REVISIONS DIFFER Either the overall revision number of PAL does not match the software revision on the control, or
the revision number of system symbols in PAL and the revision number of those on the control
do not match.
PAL ANALOG PORT ILLEGAL CONFIGURATION This is a power turn-on error that occurs when an AMP configuration error exists in the PAL
analog port configuration.
PAL ANALOG PORT/SERVO F-W INCOMPATIBLE PAL-controlled analog output port feature requires the servo firmware (f-w) revisions:
Analog servo f-w rev 0.06 or greater
Digital servo f-w re. 2.03 or greater
Consult Allen-Bradley customer support services about servo firmware updates.
PAL AXIS STATUS CANNOT CHANGE You attempted to change the status of a PAL axis (either to PAL axis or to a system axis) when it
is not allowed. Examples of when the transition is not allowed are when the axis is jogging,
performing jog retract, performing block retrace, etc...
PAL BACKGROUND TOOK TOO LONG Background PAL was not completed in the time allocated to it in AMP. Background PAL will
continue on to completion before restarting. If and when background PAL does complete in the
allocated time, this message will disappear. If this message appears continuously, the PAL
program should be rewritten, or else the AMP defined background PAL execution time should be
increased. Refer to the AMP and PAL reference manuals for more details.
PAL DIVIDE BY ZERO ERROR The PAL program tried to divide a value by zero. Check the PAL program for errors.
PAL DOES NOT EXIST There is no PAL program in the system, either on EPROM or in RAM memory. EPROMs must
be installed, or else PAL must be downloaded to RAM from ODS.
PAL INITIATED MOTION POSSIBLE While in QuickCheck mode it is possible for PAL to physically move axes. This includes any
motion generated by PAL including the PAL axis mover, or jogs that can occur in automatic
mode such as jog on the fly or manual gap elimination. This message is cleared after the first
block is executed in QuickCheck mode.
PAL OVERWRITING G54 ® G59.3 PAL is overwriting the current G54 - G59.3 offset through PAL offsets.
PAL PAGE WAITING - EXIT DISPLAY SELECT A PAL display page is being overwritten by the current screen. Pressing the {DISPLY SELECT}
softkey will display the display page.
PAL PAGE WAITING - EXIT MONITOR A PAL display page is being overwritten by the current screen. Exit the search monitor utility to
see the screen PAL is attempting to display.
PAL PAGE WAITING - SCREEN HAS PROMPT A PAL display page is being overwritten by the current screen.
PAL PROM CHECKSUM ERROR Checksum error in the PAL PROM memory. This indicates PAL has been loaded successfully
however it has failed to pass verification. Check if your flash sticks are installed properly and
are not damaged. Attempt to download a copy of the same PAL image from another project.
PAL SOURCE NOT DOWNLOADED TO CNC The PAL search monitor utility can not be accessed. The PAL search monitor utility requires the
PAL source code be downloaded with the built PAL program.
PAL SOURCE NOT LOADED The copy of PAL in flash does not contain source programs.
