Error and System Messages
Appendix B
B-40
Message Description
SERVO PROCESSOR OVERLAP The analog version of the servo sub-system provides fine iteration overlap detection. This
message is displayed if the fine iteration software on the DSP does not execute to completion in
one fine iteration.
SERVO PROM CHECKSUM ERROR The checksum test on the servo processor software stored in PROM memory has failed. This
test is performed on power-up and periodically while the system is running. Contact
Allen-Bradley customer support services.
SERVO PTO DIAGNOSTICS FAIL The servo card has failed its power-up diagnostics. Consult Allen-Bradley customer support
services.
SERVO PTO SEQUENCE ERROR The servo card has failed its power-up diagnostics. Consult Allen-Bradley customer support
services.
SERVO TIME-OUT READING ABSOLUTE ENCODER During power-up initialization of the position registers or during a homing operation, the servo
processor has failed to return a read within the required time after the absolute position has
been requested by the main processor. Consult Allen-Bradley customer support services.
SERVO TIME-OUT READING FEEDBACK During a homing operation, if there is an error reading feedback from the servo module, this
message appears. This usually occurs when the system scan time is close to the threshold at
which PAL execution can just complete and when homing more than 3 axes at a time. This
error can be avoided by homing axes individually or increasing the system scan time in AMP.
SET ZERO NOT ALLOWED ON: A set zero operation on the specified axis is not permitted. Typically this is because either the
control is not in manual mode, or the selected axis is in the process of being jogged.
SHAFT VALUE > NUMBER OF POCKETS An attempt was made to assign a shaft pocket that is greater than the number of pockets
assigned for that custom tool. The shaft pocket number must be a value between 1 and the
number of pockets assigned to that tool.
SHARED AXIS CONFIGURATION ERROR Either there are too many shared axes configured, a shared axis has the same name as some
other axis in the system, the diameter axes on a lathe are shared axes, or some other
miscellaneous configuration error occurred.
SHARED AXIS NOT IN PROCESS You have attempted to position a shared axis (or recouple a shared dual axis) not currently
available to the requesting process. A shared axis can only be positioned by the process
currently controlling the shared axis.
SHARED SPINDLE CONTENTION This is a run-time decode error. A process attempted to activate an exclusive-use spindle mode
or change the spindle speed when another process was using it. The process goes into cycle
stop.
SHIFT AWAY FROM ENDPOINT When a cylindrical grinder cycle (G84 or G85) is programmed with a shift and plunge, and the
shift increment does not move towards the cycle endpoint, this message is generated. The shift
increment must move towards the cycle endpoint.
SHIFT VALUE HAS TOO MANY DIGITS You have used incorrect search string syntax in the PAL search monitor utility.
SKIPPING SOURCE NOT INCLUDED MODULE(S) When you downloaded your PAL program the source code for some modules was not included.
The ODS software can decide to not include the source on selected modules when it determines
their is not sufficient memory on the control to hold both the PAL image and the source code.
The PAL search monitor utility will not monitor any PAL modules that do not have their source
code downloaded.
SLASH NOT ALLOWED An error occurred in G05 DH+ communications block.
SLAVE AXIS LETTER CANNOT BE PROGRAMMED An attempt was made, when using dual axes, to program the slave’s axis letter.
SPINDLE CONFIGURATION ERROR An attempt was made to configure a spindle that did not have a servo board identified in AMP to
indicate to which board the spindle is connected. The spindle must be included in the
number--of--motors AMP parameter for the board the spindle is on.
SPINDLE ERROR, AMP FIRST SPINDLE 1ST AMP order of spindles must be spindle 1, spindle 2, spindle 3.
SPINDLE ERROR, AMP SECOND SPINDLE 2ND AMP order of spindles must be spindle 1, spindle 2, spindle 3.
SPINDLE ERROR, AMP THIRD SPINDLE 3RD AMP order of spindles must be spindle 1, spindle 2, spindle 3.
