Message Description
N
NEED SHADOW RAM FOR ONLINE SEARCH Your system contains the DH+ module and you have not installed the extra RAM SIMMS that
are required to run the PAL online search monitor with the DH+ module installed. You must buy
additional RAM for a system equipped with both of these features. Contact your Allen-Bradley
Sales representative to purchase these SIMMS. Refer to your 9/Series integration manual for
details on installing additional SIMMS.
NEED SPINDLE FEEDBACK You attempted to use the solid--tapping feature or synchronization feature with a spindle that
does not have feedback.
NEGATIVE DWELL VALUE An attempt was made to execute a dwell with a negative value. Dwell values must be positive
values.
NEGATIVE F-WORD PROGRAMMED A negative feedrate was programmed in a program block. Negative feedrates are illegal.
NEGATIVE TO UNSIGNED LONG ERROR Internal math error has occurred; contact Allen-Bradley customer support services.
NEGATIVE VALUE NOT ALLOWED The minus (-) sign was used for an address which cannot be programmed with a negative value.
NET CORRECTION IS NOT ZERO For a rotary axis, the net amount of correction for axis calibration should be zero for one
complete revolution.
NET PICK/PLUNGE AWAY FROM ENDPOINT The primary and secondary pick/plunge amounts, when added together, are in the direction
away from the programmed endpoint.
NETWORK COMMUNICATION DISABLED When editing or restoring communications configuration data, this message is displayed.
NETWORK PASSTHRU COMMUNICATIONS FAULT A communication error has occurred between the controls ethernet module and the ODS
passthrough device (typically a PLC).
NEVER OPENED THE PROGRAM An attempt was made to edit a program that was not currently open.
NEW TOOL OFFSET SETUP BUT NOT ACTIVATED The tool offsets for the active tool were changed, but not activated in the current block. These
new tool offsets will not be activated until the set-up blocks are cleared of the old tool offsets and
refilled with the new tool offsets.
NO ACTIVE PROCESS CONFIGURED The AMP has been loaded into a multi-processing system that has no processes configured as
active.
NO ACTIVE PROGRAM An attempt was made to do a search when no part program is active.
NO AXIS CONFIGURED The current active version of AMP does not have any axes configured as usable. All axes are
configured as unfitted.
NO CHARACTERS ENTERED FOR SYMBOL You have used incorrect search string syntax in the PAL search monitor utility.
NO DEPTH PROBE TRIP A G26 block reached its programmed endpoint without the adaptive depth probe being tripped.
The part surface was not detected by the adaptive depth probe before the G26 block completed.
NO FEEDRATE PROGRAMMED A command for axis motion was executed when there was no active feedrate. Applies to
non-rapid moves (G01, G02, or G03).
NO FURTHER RETRACE ALLOWED The control has reached a block during retrace from which no further retrace is permitted.
NO INTERSECTION EXISTS There is no mathematical intersection for the QPP blocks as programmed.
NO MARKER FOUND ON : The encoder marker was not detected when homing the indicated axis. Homing was
unsuccessful.
NO MORE MDI BLOCKS Cycle start was requested during MDI mode when there were no MDI blocks present to be
executed.
NO MORE MDI BLOCKS TO RESET A reset was requested during MDI mode when there were no incomplete or unexecuted MDI
blocks reset.
NO OFFSET ACTIVE An offset must be active before the control will allow the offset to be changed. This check is
used so that the control will no the method and direction of the offset will be the same as the
previous offset.
NO OPTIONAL FB PORT ON ANALOG SERVO The system was incorrectly AMPed with optional feedback module on an analog servo module.
