Message
Description
ILLEGAL DUAL CONFIGURATION
Both dual master axes names have the same letter OR when assigning dual groups in AMP,
dual groups must be assigned in contiguous order, starting with group 1, 2, 3, 4, and 5. You can
not assign axes to dual group 3 without axes having been assigned to dual groups 1 and 2.
ILLEGAL DUAL LINEAR/ROTARY CONFIGURATION
The dual group cannot contain a mixture of linear and rotary axes.
ILLEGAL FILENAME
An attempt was made to create a program using a program name that contains illegal
characters. A different program name must be used.
ILLEGAL G40 EXIT BLOCK
An illegal sequence of exit moves was programmed in a G40 exit block.
ILLEGAL G88.5 OR G88.6 PARAMETERS
Illegal parameters were entered in a G88.5 or a G88.6 programming block.
ILLEGAL G99
An illegal G99 was entered in a programming block.
ILLEGAL G-CODE IN INTERRUPT MACRO
An illegal G-code has been programmed in a program called by a program interrupt. G24, G25,
G26, G40, G41, G42, G52, G92, and G92.1 cannot be programmed in an interrupt program.
ILLEGAL G-CODE IN POCKET
An illegal G-code was entered in a G88 or G89 pocket-programming block.
ILLEGAL I/O RING DEVICE CODE
There is a device on the I/O ring that cannot be identified.
ILLEGAL I/O RING RACK SLOT CODE
There is a card in the 1771 I/O rack that the I/O ring cannot use.
ILLEGAL INPUT
A number was input from the keyboard instead of a character, or a character was input instead
of a number.
ILLEGAL MACRO CMD VIA MDI
A paramacro command that cannot be used in MDI mode was programmed. This also can
include an illegal sub-program return M99 code.
ILLEGAL MASTER AXIS NAME
Slave axes that do not have a master have been configured for a dual group OR you have
assigned a $ axis name as a group master. Axis names beginning with a $ can not be assigned
as the master axis for a dual group (first logical axis assigned to the group).
ILLEGAL PAL PRIORITY MESSAGE
This error message displays each time your PAL logic program attempts to save a machine
error message that contains dynamic data in the error log. Contact your system installer for
assistance with this problem.
ILLEGAL PASSWORD
A password was entered that was not assigned to one of the 8 different password levels. Make
sure that no one has changed the passwords by using {ACCESS CONTRL}.
ILLEGAL PLANE -- USING SLAVE AXIS
This is a power turn-on message. When using dual axes, one of the slave axes was AMPed as
part of the plane configuration. Only master can be used in the plane configuration.
ILLEGAL PLANE DEFINITION
The axis plane assignment made in AMP is incorrect. It can also occur if the two axes assigned
to a plane have the same axis name.
ILLEGAL PROGRAMMED RETURN GROUP
The tool group programmed in an M06 block must be the currently active tool group that is being
replaced (not the tool group you are changing to). This requirement is configured in AMP by the
system installer.
ILLEGAL PROGRAMMED RETURN TOOL
The tool number programmed in an M06 block must be the currently active tool number that is
being replaced (not the tool number you are changing to). This requirement is configured in
AMP by the system installer.
ILLEGAL RANDOM TOOL TABLE ASSIGNMENT
An attempt was made to program a G10.1L20 block that would assign a tool to a tool pocket that
already has a tool assigned to it.
ILLEGAL RECIPROCATION INTERVAL
The programmed reciprocating interval is greater than the total rollover distance.
ILLEGAL ROTATION PLANE SELECTED
When using the external part rotation feature, the external part rotation plane selected on the
rotation parameter screen is not the currently active plane in the program block being executed.
ILLEGAL SPINDLE PROCESS NUMBER
An illegal process number was used to indicate a process that uses one of the spindles.
INCOMPATIBLE PAL SOURCE
The PAL search monitor utility can not be accessed. The PAL search monitor utility requires
PAL program built with a newer version of ODS.
