Fanuc SPOT Alarm Codes

SPOT-000 WARN Unknown error (SWG0)
Cause: An internal error has occured.
Remedy: Cold start the controller
________________________________________________________________
SPOT-001 PAUSE Backup not closed %s
Cause: The backup state spot welding instruction BU=* was used before a weld, but the backup state
was in the open (BU=O) position at the time the instruction was executed. Note: BU=* indicates that
the backup state remains unchanged from the last position. To use this command before a weld, the
previous backup state must be BU=C (closed position).
Remedy: Make sure that the backup state is closed when using the BU=* command. Either change
BU=* to BU=C, or insert a BACKUP=CLOSE statement before this statement.
________________________________________________________________
SPOT-002 PAUSE Iso contactor fault %s
Cause: The isolation contactor on the specified weld controller is in a fault condition. If no program
is running, then this message is posted if either the Iso contactor output is high or the Iso contactor
input is high. If a program is running or a manual weld is being executed then the output, if defined,
must be high and the input, if defined, must be high too.
Remedy: Verify the contactor state. Make sure that the correct contactor instruction has been
programmed in the teach pendant program. Verify the input status and configuration in the Weld
Interface I/O screen. Using the teach pendant:
1. Press I/O.
2. Press F1, [TYPE].
3. Select Weld Interface.

controller Weld Enable status. These must be the same. The Soft Panel can be accessed using the
teach pendant.
1. Press MENUS.
2. Select Soft Panel.
3. Press F2, Applic.

2. Press F1,[TYPE].
3. Select Weld Interface.
Verify that the correct configuration is being used within the Spot Config menu. This menu can be
accessed at Controlled start.
________________________________________________________________
SPOT-012 PAUSE Bad schedule (S=*) %s
Cause: An inavlid weld schedule was programmed in the teach pendant program.
Remedy: Check the S= value of the current line of the teach pendant program. The smallest schedule
number allowed is 0. For digital weld controllers, the the largest schedule number allowed depends on
the width of the Weld Schedule group output. If this GOUT is 4 I/O points wide, then the maximum
schedule is 15. If the GOUT is 5 I/O points wide, then the maximum scheudule is 31. For serial weld
controllers, the maximum schedule is 32. Re-program the S= value in the teach pendant program.
________________________________________________________________
SPOT-013 PAUSE Undefined pressure (P=*)
Cause: The valve pressure spot welding instruction P=* was encountered in a teach pendant program,
but no previous pressure value had been assigned. Note: P=* indicates that the valve pressure
remains unchanged from the last value.
Remedy: Be sure to include a direct pressure value instead of using &qout;*&qout;.

changes are done with TPE macros. Make sure that a call to the correct macro is made before
attempting the SPOT or BACKUP operation.
________________________________________________________________
SPOT-042 WARN Stud Welder Time Out Fault
Cause: The robot detected a Stud Welder Time Out Fault from the current controller during a weld.
This fault occurrs when the controller does not detect a completed weld or a bad weld after the timer

of the gun at the weld spot. Also check the schedule settings.
________________________________________________________________
SPOT-044 WARN Stud Welder Arc Voltage Fault
Cause: This fault is signaled by the Stud Weld controller if the voltage sensor reports too little arc
voltage during the weld process. May result in a poor quality weld.
Remedy: The stud checker will automaticly verify the quality of the weld. If bad, check the position
of the gun at the weld spot to insure that the tip is the correct distance.
________________________________________________________________
SPOT-045 WARN No Current detected: %s
Cause: The robot did not see the current sensor input go high throughout the weld, indicating no
current
Remedy: Check the weld controler to verify that the schedule does include a heat setting. If so,
verify operation of sensor
________________________________________________________________
SPOT-046 WARN Weld auto retried %s time(s)
Cause: The Auto Retry Weld feature encountered a weld fault and retried the weld the indicated
number of times. This warning is posted for every. SPOT instruction encountered in which the
weld was retried at least once.
Remedy: This is just a warning to let the operator know that a weld was retried, and to alert the
operator that weld controller maintenance may be required.
________________________________________________________________
SPOT-047 WARN Collision Detection Alarm
Cause: A Collision Detection Alarm has been detected. The robot might have collided with an object,

Cause: The data contained in the Collision Guard macro register is not an integer or is not in the
range of 1 to 200.
Remedy: Enter the correct data into the Collision Guard macro register.
________________________________________________________________
SPOT-050 PAUSE Bad Pressure (EP=*) %s
Cause: An inavlid binary equalization pressure was programmed in the teach pendant program.
Remedy: In the teach pendant program, check the equalization pressure spot welding instruction
EP= value. Note: The smallest valve pressure allowed is 0. For digital weld controllers, the largest
pressure number allowed depends on the width of the Equalization Pressure group output. If this
GOUT is 4 I/O points wide, then the maximum pressure is 15. If the GOUT is 5 I/O points wide, then
the maximum pressure is 31. For serial weld controllers, the maximum pressure is 15. Re-program
the EP= value in the teach pendant program.
________________________________________________________________
SPOT-051 PAUSE Undefined Pressure (EP=*) %s
Cause: The equalization pressure spot welding instruction EP=* was encountered in a teach
pendant program, but no previous pressure value had been assigned. Note: EP=* indicates that the
equalization pressure remains unchanged from the last value.
Remedy: Be sure to include a direct equalization pressure value instead of using &qout;*&qout;.

Cause: This is a warning to inform you that weld simulation has been enabled. This message is
posted one time when weld simulate enable has changed from FALSE to TRUE. Note: weld simulate
is a test mode function.
Remedy: Disable weld simulation, if weld mode simulation is not desired.
________________________________________________________________

simulate mode is active. Weld simulate is only available when weld mode is disabled. Therefore,
weld simulate will also be disabled.
Remedy: Set weld mode to disable, and re-enable weld simulate if you still want to use weld
simulate; otherwise no action is needed.
________________________________________________________________
SPOT-302 WARN Weld sim Disabled
Cause: This warning informs you that weld simulation has been disabled. This message is posted
one time, when $spotcofig.$sim_enb changes from TRUE to FALSE. Note: Weld simulate is a test
mode function.
Remedy: Set weld mode to disable, and re-enable weld simulate if you still want to use weld
simulate; otherwise, no action is needed.
________________________________________________________________
SPOT-303 WARN %s
Cause: This message is posted to identify a spot that executed while weld simulation was active. The
message will look like: SPOT-303: SimWld (Progname,Line#). Note that this message is only posted
if $spotcofig.$weld_sim = TRUE, and $spotcofig.$sim_warn = TRUE
