4349 LINEAR SERVO
FLOAT TOOL
POSE CONTROL
SPECIFICATION
ERROR
--- A logical error occurred in the des-
ignation for tool orientation control
of the linear servo float.
• Reset the alarm, and then try again.
• Turn the power OFF then back ON.
If the error occurs again, contact your
Yaskawa representative.
4350 LINEAR SERVO
FLOAT EXECU-
TION ERROR
--- While the servo float was in execu-
tion, the linear servo float can not
be executed.
Check the job.
4351 BELT DISCON-
NECTION
DETECTION
--- The driving belt may be discon-
nected because the torque
decreased below the normal value.
Check the belt, and replace it if necessary.
4352 TWIN DRIVE
OVER
DEVIATION
--- The deviation of the position error
pulse from the twin drive axis
exceeded the allowable limit with
twin drive function.
Check the load.
4353 DEFECTIVE
TAUGHT POINT
(ENDLESS)
--- Endless motion impossible
• The feedback pulse value
exceeded the maximum value
(maximum number of pulses ±
536870912)
Reset the alarm.
4354 FILE NO.
ERROR
(SHOCK LEVEL)
--- The collision detection file for exclu-
sive use for the SVSPOT is used
with the SHCKSET instruction.
Do not use the collision detection file for
exclusive use for the SVSPOT with the
SHCKSET instruction.
4355 EXTERNAL
PRES DETECT
(SERVOFLOAT)
--- An external force above the thresh-
old was detected on the servo-float
executing axis.
Check the job.
4356 ARM CTRL
PARAMETER
ERR
(OBSERVER)
--- The search of motor-gun equalizing
function cannot be executed
because no observer (including col-
lision detection) is specified.
If the error occurs again, contact your
Yaskawa representative.
4357 IMPOSSIBLE
SRCH
(EQUALIZE
TEACH)
--- The manipulator orientation at the
execution of search of the motor-
gun equalizing function is the orien-
tation for the singular point.
Check the job.
4358 DUPLICATE
PRESS ERROR
--- The pressuring instruction was exe-
cuted with manual pressurization
during pressuring.
Do not execute the pressuring instruction
with manual pressurization during pressuring.
4359 CONVERTER
ERROR
--- An error occurred in the converter. • Turn the power OFF then back ON.
If the error occurs again, replace the servo
control circuit board or the converter.
4360 WAFER ALIGN-
MENT ERROR
(SERVO)
Deci-
mal
data
An error occurred in communica-
tions with the prealigner.
Check the connection of prealigner.
4364 GUN SOFT LIMIT --- The gun axis exceeded the soft-
ware limit during pressuring opera-
tion.
• The error could occur due to the tip
removed or the tip mis-installation. Verify
the pressuring status.
• Set the pulse software limit again consider-
ing the wearing of chip and the deflection of
gun arm.
If the error occurs again, contact your
Yaskawa representative.
4365 EXCESSIVE
DETECTION
RAN
GE
(GUN ELEC-
TRODE HIT
POINT)
Physi-
cal
axis
bit
In comparison to the position,
where the gun electrode hits the
welded target, at the previous wear
detection, the position during pres-
suring exceeded the allowable limit
which had been set in the motion
limit for which the fixed (movable)
gun electrode hits the welded tar-
get.
• The error could occur due to the tip
removed or the tip mis-installation. Verify
the pressuring status.
• Adjust the set value of the gun condition file.
