Error and System Messages

Message
Description
POCKET IS PART OF CUSTOM TOOL
An attempt was made to assign a tool to a tool pocket that is already used by a custom tool.
Custom tools are assigned to tool pockets that are shown with an XXXX next to the pocket
number on the random tool table.
POCKET MILLING SHAPE IS INVALID
A parameter is missing in the G88 programming block.
POINT ALREADY EXISTS
The point that you are trying to enter is already in the axis calibration table.
PORT B IS BUSY
This message appears when you press {SYSTEM SUPORT}, {MONITOR}, or {SERIAL I/O} and
port B is busy.
PORT IS BUSY - REQUEST DENIED
An attempt was made to output or input information to or from a serial communications port that
is already being used by some other device or is selected as the port that an active program is
coming from.
PREVIOUS ABORT COMMAND NOT COMPLETE
This message is displayed when the communications “abort”key is entered before the last abort
requested has completed.
PROBE/CONTROLLING AXIS CARD DIFFERENT
Both the adaptive depth probe and the adaptive depth probe controlling axis (typically the axis
that positions the probe) must be attached to the same servo card. You must re-AMP your
system and re-arrange your servo wiring so that the adaptive depth probe and it’s corresponding
servo are on the same servo card.
PROBE CYCLES CALCULATION ERROR
The servo module was unable to compute the probe position when the probe is fired. Make
sure that all measurement points are within the programmed range entered for the probe cycle.
Lower the feedrate during the probing operation and try again.
PROBE CYCLES PROGRAMMING ERROR
Either not enough or too many axes are programmed in a probing cycle block.
PROBE ERROR
A probing cycle has reached the outer limits of the tolerance band without firing the probe, or the
probe has fired before entering the tolerance band.
PROBE IN USE BY OTHER PROCESS
On a dual processing control only one probing function is allowed at any one time. Probing can
not be performed by both processes simultaneously. You must wait for probing to complete in
one process before probing in the other process.
PROBE IS ARMED, CAN’T ADJUST SERVOS
With the probe armed through a probing operation, until the probe fires or the probe is disarmed,
other online AMP servo parameters like torque, feedforward percentage, gain, etc., are not
allowed to be changed.
PROBE TRIP DURING DECEL
An adaptive depth probe trip occurred after the program block reached endpoint. The trip was
made while the control was waiting for the following error to collapse after interpolation is
complete. Avoid this error by reducing axis speed (thus reducing following error) or by moving
the adaptive depth block endpoint further into the part.
PROCESS SWITCH NOT CURRENTLY ALLOWED
On a dual-processing system, you cannot switch processes while in graphics or in digitize.
PROGRAM ACTIVE
An attempt has been made to delete or perform some other operation to a program that was
activated for automatic execution. The program must be deactivated using the {CANCEL
PRGRAM} softkey.
PROGRAM ACTIVE IN ANOTHER PROCESS
This dual lathe error appears when one process attempts to open a file for edit, deletion, etc.,
while that file is active in another process.
PROGRAM BEING EDITED
An attempt has been made to copy, verify, or perform some other operation on a program that is
still in the edit mode. It is necessary to press the {EXIT EDITOR} softkey from the edit menu to
properly end an editing operation.
PROGRAM BLOCK TOO LONG
More than 128 characters were entered into a single block.
PROGRAM CURRENTLY IN USE
A subprogram or paramacro program was called that is currently being used to perform some
other operation (such as editing or copying). Typically, this message is the result of attempting
to edit a program that was not properly closed. A program remains in the edit mode until the
{EXIT EDITOR} softkey is pressed from the program edit menu.
PROGRAM NAME TOO LONG
An attempt was made to create a program with a program name longer than 8 alphanumeric
characters. If a large, descriptive program name is desired, a comment may be added to the
right of the program name using the {PRGRAM COMENT} feature.
