Description
6 L.C. Rated Output 0.000 to 2.500 mV
Inputs the rated output shown on the certificate of
analysis of the purchased load cell.
(Not changed by initialization.)
7 LS Input Validity
Valid(0)
Invalid(1)
Sets whether to use the force-detecting signal input.
Valid(0): Use
Moves to the Before Weld Work after the LS signal is
input.
Invalid(1): Do not use
Moves to Squeeze-Time after the ST-DISP signal is
input.

Force Measure
Mode
SQNC(0)
SH1(1)
SH2(2)
TANG(3)
OFF(4)
Selects the measurement mode of the load cell.
SQNC(0): Sequence mode
Mode for connecting the load cell only. The
ST-FORCE signal is input and the Before Weld Force
is measured after Squeeze-Time. When it is within
the upper/lower limit range, the sequence moves to
Weld-Time and the WELD START signal is output.
The sequence moves to Hold-Time after Weld-Time
and the After Weld Force is measured after
Hold-Time. When it is within the upper/lower limit
range, the GOOD signal is output. When outside the
range, the NG signal is output.
SH1(1): Sample hold 1 mode
Mode for connecting the load cell only. Only when the
ST-FORCE signal is input, the Before Weld Force is
measured. When it is within the upper/lower limit
range, the GOOD signal is output. When outside the
range, the NG signal is output.
SH2(2): Sample hold 2 mode
Mode for connecting the load cell only. The sequence
moves to Weld-Time and the WELD START signal is
output when the value reached the Tangential Force
setting. The weld force peak is measured during the
Weld-Time. When it is within the upper/lower limit
range set in the After Weld Force, the GOOD signal
is output. When outside the range, the NG signal is
output. When the Weld-Time setting is shorter than
settings of Force Sampling and Force Average, the
measurement is not done and “-” is displayed.
Note) The ST-FORCE signal is not used. The weld
force is accepted at all times except during
sequence.
TANG(3):
Tangential mode
Mode for connecting the load cell only. After the
ST-FORCE signal is input, the sequence moves to
Weld-Time when the value reached the Tangential
Force setting, the WELD START signal is output, and
then the sequence moves to Hold-Time after
Weld-Time. The After Weld Force is measured at the
point set in Tang Measure Point. When it is within the
upper/lower limit range, the GOOD signal is output.
When outside the range, the NG signal is output.
OFF(4): Load cell off mode
Mode that the measurement of the load cell is not
done.
(Ignored when the Disp Measure Mode is set to SYNC.)
When using the load cell alone without using the
displacement sensor, use SQNC, SH1, SH2 or TANG.
Also, set the Disp Measure Mode to an item other than
SYNC(0).
