POS SENSOR
FAIL COMMUNICATION
173
Communication error with the position
sensor.
Check that the position
sensors are properly wired.
Contact service center.
POSITION FAIL
STRUCTURE MODIFIED
174
Position sensor error on measuring
the coordinate, the electrode is very
worn out or the geometry of the spot
welder structure changed.
Check for the absence of
anomalous movements in
the structure of the spot
welder.
Delete the error and repeat
the zero procedure for the
coordinate.
THICKNESS
UNDER LOW LIMIT
175
The initial thickness of the sheets
between the electrodes is less than
that set in the limit.
Reset the error and check
the material present
between the electrodes.
THICKNESS
OVER HIGH LIMIT
176
The initial thickness of the sheets
between the electrodes is more than
that set in the limit.
Reset the error and check
the material present
between the electrodes.
DYNAMIC MODE
FAIL COMPENSATION
177
The DYNAMIC WORKING MODE was
not capable of completing the weld
within the max time set by the user.
Reset the error and check
the welding that was just
carried out. Repeat the
learning procedure if
needed.
MISSING R
COMPENSATION
178
The QUALITY-R parameter was
activated without correcting the
resistance of the arms on turning the
machine on.
Reset the error, set the
QUALITY-R parameter to
zero and carry out the
correction spot and reset
the original value of the
QUALITY-R parameter.
MATERIAL RES
UNDER MIN VALUE
179
The initial resistance of the material is
less than the minimum set value.
Reset the error and check
the material present
between the electrodes.
MATERIAL RES
OVER MAX VALUE
180
The initial resistance of the material is
more than the maximum set value.
Reset the error and check
the material present
between the electrodes.
