4-22
OFF Normal mode not using the transformer selecting function.
1-5
First, welding is performed using the selected schedule No. (N), then
using the next schedule No. (N+1).
Next, welding is performed in sequence using successive schedule
numbers (N+2, N+3, N+4...).
At this time, welding is performed in sequence using transformer No.
(TRANS #) set on each SCHEDULE screen.
For example, when schedules 2, 3, 4, 5, and 6 are selecting
transformers 4, 2, 3, 5, and 1 respectively, and you start welding
using schedule 2, welding is performed using schedule 2 (TR#4) first,
then schedule 3 (TR#2), schedule 4 (TR#3), schedule 5 (TR#5), and
lastly schedule 6 (TR#1). (See drawing above.)
Also, when schedule 255 is selected, welding is performed in
sequence using schedule 255 first, then schedule 1, schedule 2...
Squeeze delay time (SQD) is inserted in the first welding (N) only.
SQD set in the second (N+1) or later is ignored. Valve outputs the
number set in the selected schedule No. Different valve No. set in
N+1 or later does not function.
The same can be said for 1-1 to 1-4 settings.
1-4
Like the 1-5 setting, welding is performed in sequence using 4
successive schedule numbers from the selected schedule No. When
the schedule 2 is selected, welding is performed using transformer 4
(TR#4) to TR#5.
1-3
Like the 1-5 setting, welding is performed in sequence using 3
successive schedule numbers from the selected schedule No. When
the schedule 2 is selected, welding is performed using transformer 4
(TR#4) to TR#3.
1-2
Like the 1-5 setting, welding is performed in sequence using 2
successive schedule numbers from the selected schedule No. When
the schedule 2 is selected, welding is performed using transformer 4
(TR#4) to TR#2.
1-1
Welding is performed using the transformer of the selected schedule
No. When the schedule 2 is selected, welding is performed using
transformer 4 (TR#4).
(Note 1) In case of 1-1 to 1-5 settings, the following functions cannot be used:
Repetition mode by OFF time setting
RE-WELD function
(Note 2) Error/caution during welding when the transformer selecting function
is used.
When the monitored value is outside the range of upper/lower limit of
current, voltage, power, or pulse width, the function changes
depending on the setting of END SIGNAL MODE.
When END SIGNAL MODE is 0 or 2, the caution signal and END
signal are output after all weldings are completed. Also, welding is
performed again at the next start.
When END SIGNAL MODE is 1, welding stops when the monitored
value is outside the range and error signal is output until the error
reset signal is input. The END signal is not output. Also, welding is
not performed again at the next start.
