Error and System Messages

Message Description
OPTIONAL RAM SIMM BAD/MISSING The control has discovered the RAM SIMMs for the extended storage option are either
damaged or missing. The RAM SIMMs must be installed or replaced. Contact your Allen
Bradley sales representative for assistance.
OTHER PROCESS G CODE CONFLICT On a dual processing system, one process has a conflicting G code active when you attempted
to activate a G26 depth probe cycle. For example, process one executes a G26 while process
two has an axis in feed to hard stop which is on the same servo card as the depth probe.
OVER SPEED A servo motor is turning at an RPM that is greater than the maximum RPM allowed for that
servo as defined in AMP by the system installer. For digital spindles this error can result from
maximum RPM gear range 1 being set higher than your AMPed allowed Maximum Motor
Speed.
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.
