Message Description
PLUNGE MOTION NOT PROGRAMMED In your pocket cycle you have either not programmed a final depth, or the final depth you have
programmed is equal to the depth of the cutting tool at the starting point of the cycle. The
location of the cutting tool when the pocket cycle is programmed must be at a different depth
than the final programmed depth of the cycle.
PLUNGE NOT ALLOWED A plunge that will cut into the pocket wall was requested in a G89 irregular pocket cycle.
PLUNGE STEPS MIS--PROGRAMMED The rough, medium, and fine-feed depths in the cycle block are not programmed correctly. This
is possible if the data in the block is incorrect or if the data in the modal values of the parameter
not programmed in the block are incorrect.
POCKET END NOT SAME AS START A pocket end-point that is not the same as the pocket start-point was programmed in a G89
irregular pocket cycle.
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.
POWER DOWN ERROR, POSSIBLE PAL DATA LOSS This message can be displayed on power up of the contol. When it occurs, it indicates that the
control was shut doen abnormally , possible from a control “watch--dog time out”. You must take
appropriate steps to insure that the PAL program can still function properly with loss of
temporary data.
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.
