Message
Description
INVALID FB COUNTS
At power up the control checks the AMP configured position and velocity feedback counts per
revolution. If either of these parameters are invalid (for this hardware type) this error appears
and the control is held in E--Stop.
INVALID FDBK/MTR TYPE COMBO
When changing between an executive from system 9.xx to 10.xx some major changes occurred
to how a servo is configurated in AMP. When copying this AMP project from 9.xx to 10.xx you
must open and reconfigure some of the AMP servo group parameters before saving and
downloading to the control.
INVALID FILE TYPE
An error has occurred in a file that has been sent from the ODS workstation to the control.
Typically it is the result of ODS sending the wrong file type to the control (for example, an AMP
file is sent when a PAL download is taking place, etc.). Attempt to download the file again,
making sure that the correct file type is selected when downloaded.
INVALID FIXED DRILLING AXIS
The axis selected as the drilling axis is an invalid axis for a drilling application.
INVALID FORMAT SPECIFIED IN B/DPRNT CMD
Improper format was used in the paramacro command (BPRNT or DPRNT) that outputs data to
a peripheral device.
INVALID FUNCTION ARGUMENT
An invalid paramacro argument was used in a paramacro function. The argument contains
either bad syntax or an illegal value.
INVALID G10 CODE
The format for a G10 block is not correct. Refer to your user manual for the correct format for
the G10 block that is currently being programmed.
INVALID IN ANGLED WHEEL MODE
A feature that is not available in G16.3 mode, or G16.4 mode or both has been programmed.
Refer to your grinder users manual angled-wheel grinder section for a description of features not
available on an angled-wheel grinder.
INVALID INFEED (P WORD)
Infeed value (P-word) is not in valid range. The valid range for a P-word during a threading
cycle is whole numbers 1 though 4.
INVALID INPUT VALUE
The data entered is invalid for the current operation being performed.
INVALID INTERFERENCE AREA
A G10 block has programmed a zone where the plus value is less than the minus value.
INVALID INTERFERENCE CHECK AXIS
An axis from the wrong process was AMPed. Unless a shared axis is used in the zone, the axis
defined to make up an interference area must be in the process the zone is defined for.
INVALID LATHE AXIS
An illegal code was encountered during cylindrical interpolation programming.
INVALID LIFE TYPE
The current program is attempting to enter an invalid tool life type for a tool group in the tool
management tables. Valid tool life types are type 0, 1, or 2. Tool life type is programmed in a
G10 block following a I-word.
INVALID M99 IN MAIN PROGRAM
An M99 part program rewind and auto start was programmed in the middle of the main program.
An M99 can be programmed only at the end of a part program.
INVALID MACRO COMMAND
The IS and IM commands are reserved for use by the control only for program interrupts. They
cannot be entered in a part program or MDI program.
INVALID MACRO FROM TAPE
You have programmed a paramacro command that cannot be executed from tape.
INVALID NUMBER OF POCKETS
This error occurs when using G10 L20 to enter random tool data and the number of pockets
needed for the tool is invalid.
INVALID OFFSET NUMBER
An offset number out of the range of allowable offset numbers (either too large or too small) was
programmed.
INVALID OPERATOR IN EXPRESSION
Check expressions to make sure they are correct.
INVALID OPERATOR IN PARAMACRO EXPRESSION
The control has encountered a non-mathematical operator (character) in a paramacro
expression or calculate operation.
INVALID OUTPUT FORMAT
An error occurred in G05 DH+ communications block.
INVALID PARAMACRO ARGUMENT ASSIGNMENT
An argument assignment in a block that calls a paramacro program contains either an invalid
argument specification or a syntax error was made in the argument.
INVALID PARAMETER NUMBER
An attempt was made to assign or read the value of a paramacro parameter that does not exist.
