Message
Description
L VALUE OUT OF RANGE
An L-word repeat count was programmed larger than the system is capable of performing
(typically a maximum L of 9999 is permitted). A second block will need to be programmed to
duplicate the commands again. Enter a smaller L-word for both blocks.
L-WORD CANNOT BE GREATER THAN TOOL RADIUS
The programmed L-word value in a G88.5 or G88.6 hemispherical pocket cycle is greater than
the programmed tool radius. The incremental plunge depth of a hemispherical pocket cycle
cannot be greater than the tool radius.
L- WORD OUT OF RANGE
More than 1000 spark-out passes were specified by the L-word in a grinder fixed cycle.
LARGER MEMORY - REFORMAT
This message typically occurs after a new AMP or PAL has just been downloaded to the control.
There is now more memory available for the RAM disk, but you need to reformat to use it. If
desired, you do not have to reformat RAM and can continue to run the control with the RAM disk
at its current size.
LEAD WORD FORMAT FINER THAN
The word format programmed is requesting a finer resolution than the axis word format for the
corresponding axis allows. These word formats are set in AMP.
LENGTH OFFSET AXIS MISSING IN PROCESS
You have configured the tool length axis as a shared axis and it is currently not being controlled
by the process requesting to activate a tool length offset. The shared length axis must be
returned to the process attempting to activate the tool offset. Or tool offsets were programmed
for an axis that is configured in AMP as unfitted.
LESS MEMORY - REFORMAT
This message typically occurs after a new AMP or PAL has just been downloaded to the control.
There is now less memory available for the RAM disk, and you must reformat to use the RAM
disk.
LETTER OR DIGIT MUST FOLLOW $, %, !, &, OR #
You have used incorrect search string syntax in the PAL search monitor utility.
LETTER OR DIGIT MUST FOLLOW $, %, ! OR #
You have used incorrect search string syntax in the PAL search monitor utility.
LETTER OR DIGIT MUST FOLLOW $, % OR !
You have used incorrect search string syntax in the PAL search monitor utility.
LETTER OR DIGIT MUST FOLLOW $, % OR !
You have used incorrect search string syntax in the PAL search monitor utility.
LETTER OR DIGIT MUST FOLLOW #
You have used incorrect search string syntax in the PAL search monitor utility.
LIMIT EXTRN DECEL SPEED ON
Dual axes have limited the external decel speed AMP value. An axis in the dual-axis group was
AMPed with a lower value.
LIMIT MANUAL DLY CONSTNT ON
Dual axes have limited the manual delay constant AMP value. An axis in the dual-axis group
was AMPed with a lower value.
LIMIT MAX CUTTING FEED ON
Dual axes have limited the maximum cutting feedrate AMP value. An axis in the dual-axis group
was AMPed with a lower value.
LIMITED ACC/DEC RAMP ON
Dual axes have limited the acc/dec ramp AMP value. An axis in the dual-axis group was
AMPed with a lower value.
LIMITED RAPID FEEDRATE ON
Dual axes have limited the rapid feedrate AMP value. An axis in the dual-axis group was
AMPed with a lower value.
LIMITED VELOCITY STEP ON
If the velocity step AMP value is not the same for all axes of a dual group, the control will adjust
them to the limiting axis.
LOW VOLTAGE ON FLASH STICKS
Call Allen-Bradley Support Services.
LOWER > UPPER
A value entered in the programmable zone table for zone 2 or 3 results in a lower limit value
being greater than the upper limit. The upper limit must always be greater than the lower limit.
M
M02 OR M30 FOUND - REQUEST TERMINATED
This error occurs if an M02 or M30 is found before the requested block while searching during a
mid-program start. The search will be terminated at the M02/M30 block.
MACHINE HOME REQUIRED OR G28
An attempt was made to program an axis move before the axes were homed. Axes can be
homed manually or by programming a G28 block.
MASTER HAS TO BE AMPED FIRST
The dual master axis has to be configured first in the AMP data base.
