Description
HARDWARE ERROR #15
The servo communications data echo diagnostic test between the main processor and the servo
processor has failed. Consult Allen-Bradley customer support services.
HARDWARE OVERTRAVEL (+)
The indicated axis has reached a travel limit in the positive direction.
HARDWARE OVERTRAVEL (-)
The indicated axis has reached a travel limit in the negative direction.
HIPERFACE COMMUNICATION ERROR
A serial communications error (e.g., CHECKSUM, TIMEOUT) was detected within the SINCOS
device during power--up. If this error occurs at PTO, check your feedback device to make sure it
is not disconnected.
HIPERFACE PASSWORD FAILURE
During the SINCOS device’s alignment procedure, the logic used to set the passwords detects
an incorrect password. A section of the code will repeatedly attempt various combinations of
each of the passwords to correct the error condition.
HOME TOLERANCE EXCEEDED
This error condition occurs when the homing operation of the indicated axis is aborted due to
the condition of the axis stopping off of the home switch in excess of 3/8 of an electrical cycle of
the feedback device away from a null marker. If this problem persists you may need to adjust
either the home switch position, or the home switch trip dog, or the feedback position. This may
also require you to adjust the AMP Home Calibration parameter for this axis.
HOME REQUEST ON A PARKED AXIS
An attempt was made, while using dual axes, to do a homing operation on a parked axis.
HOMING NOT COMPLETED
An attempt was made to execute a programmed axis move before the axes have been homed.
Axes must be homed before they can be moved through part program or MDI commands.
I
I/O RING COMMUNICATIONS ERROR
A communication error has occurred in the fiber optic I/O ring. This is usually caused by a
broken or disconnected fiber optic cable.
I/O RING NOISE WHILE IDLE
An illegal character was detected by an optical receiver while the I/O ring should have been idle.
The system will try to reset itself. If it cannot reset itself, the system enters E-Stop.
I/O RING NOT CONFIGURED
The control cannot run the I/O ring if it was not configured and downloaded from ODS or
resident in the PAL PROMs.
I/O RING TIME-OUT
A very large foreground PAL program, combined with a large number of I/O ring devices, has
created timing problems for I/O ring communications. Reduce PAL program size by deleting
unnecessary rungs and optimize the execution of others.
ILLEGAL (/) VALUE
A block delete slash value greater than /9 was programmed. There are only 9 block deletes
available.
ILLEGAL (G) CODE
An illegal G-code value has been programmed.
ILLEGAL (M) CODE
An illegal M-code value has been programmed.
ILLEGAL ANGLE VALUE
A QuickPath Plus block has defined the angle of the next block incorrectly. There is no possible
path that connects the two tool paths to the programmed end-point using the entered angle.
ILLEGAL APPLICATION COMMAND FROM TEACH
A non-recognized SD1-type packet was received in a CMD=61 DF1 packet from the teach
pendant interface. Allowable SD1s are 1 -- 5.
ILLEGAL AXIS DATA FORMAT
Digitized axis data does not fit within the allowable AMPed axis format. For example, if an axis
inch format is set at 2.3 and a digitized position is recorded as 121.0, an error will be generated.
The axis display will also show “__.___”.
ILLEGAL CHARACTER
An undefined character was entered in a program block and could not be executed. Certain
characters cannot be recognized while in certain modes. Also verify that you are using the
correct axis and integrand names as assigned in AMP.
ILLEGAL CODE DURING G41/G42
An illegal code was encountered during G41/G42 programming.
ILLEGAL CODE DURING VIRTUAL C
An illegal code was encountered during Virtual C programming.
ILLEGAL CODES IN RANDOM TOOL BLOCK
An invalid parameter was entered in a G10.1L20 block that loads data into the Random Tool
table. P, Q, R, and O are the allowable parameters.
ILLEGAL COMMAND FROM ODS
A command was received from ODS that was not recognized by the control.
