Error and System Messages
Appendix B
B-44
Message Description
TOO MANY NONMOTION CHAMFER/RADIUS BLOCKS Too many non-motion blocks separate the first tool path that determines the chamfer or radius
size (programmed with a ,R or ,C) from the second tool path. A maximum number of
non-motion blocks is set in AMP by the system installer. A non-motion block is defined as any
block that does not generate axis motion in the current plane.
TOO MANY POCKETS IN ROUGHING CYCLE A maximum of 2 pockets can exist in a roughing cycle.
TOO MANY QPP NONMOTION BLOCKS Too many non-motion blocks separate the first and second tool paths with unknown
intersections in QuickPath Plus. A maximum number of non-motion blocks is set in AMP by the
system installer. A non-motion block is defined as any block that does not generate axis motion
in the current plane.
TOO MANY SHARED SPINDLES Too many spindles were specified as being shared by two or more processes.
TOO MANY SPINDLES More than one spindle is configured on the control.
TOO MANY SUBPROGRAM CALLS The maximum number of nested sub-programs was reached. Only 4 sub-programs may be
active at any one time.
TOOL CONFIGURATION WILL NOT FIT When assigning a custom tool in the random tool table, the number of pockets assigned to the
tool relative to the position of the selected shaft pocket will conflict with a different tool already
assigned to a pocket. If the custom tool is to be assigned as entered, it must be assigned to a
different shaft pocket, or the tool that conflicts with the custom tools location must be moved.
TOOL ENTRY EXCEEDS LIMIT The selected tool number entered is greater than the AMP’ed maximum tool number entered by
the system installer.
TOOL GROUP DOES NOT EXIST An attempt was made to edit a tool group in the tool life management tables that does not yet
exist in the tool directory. A group must be created by using the {TOOL DIR} softkey options.
TOOL OFFSET CHANGES NOT ALLOWED During certain cycles, G10 tool change operations are not allowed.
TOOL OFFSET REQUIRES MOTION BLOCK A tool offset cannot be changed in a non-motion block. A non-motion block is any block that
does not generate axis motion in the current plane.
TOOL RADIUS TOO LARGE The programmed tool radius in a G88 or G89 pocket cycle is too large for the pocket contour. A
smaller radius tool must be used to machine out the current pocket contour.
TOOL RADIUS TOO SMALL FOR POCKET SIZE The programmed tool radius in a G88 or G89 pocket cycle is too small for the pocket contour.
Either select a larger tool for the pocket contour or reduce the amount of material to be removed
each rough cut of the cycle.
TOP OF PROGRAM REACHED When performing one of the program search operations, the first block in the program has been
reached.
TRAVERSE NOT ALLOWED ON : An attempt was made to move an axis at rapid traverse before it was been homed. This only
applies to axes that have software overtravel limits.
TYPE 1 INTERRUPT INCOMPATIBLE WITH G24 This message occurs when returning from a type 1 program interrupt that previously interrupted
a G24 block. The interrupt is allowed however the return move is invalid since the axis was
previously in the G24 mode. You must manually intervene to continue program execution. We
recommend switching to a type 2 program interrupt.
U
UART PORT IS ALREADY OPEN The requested serial communications port has already been opened. This message will appear
if an attempt is made to send data to a port that is currently being used.
UNABLE TO OPEN PROGRAM The control cannot find the program that is requested. Make sure the program name is entered
correctly or the peripheral device has the correct programs loaded in it.
UNABLE TO OPEN THE UART PORT A serial communication port error has occurred; retry. The conditions that can lead to this error
are unusual and generally will not exist when a second attempt is made to open the port. If this
error is generated continuously, it indicates that there may be a communications port hardware
failure.
