In 4) and 5), up to 255 schedules can be used by combining schedule signals
SCH1/2/4/8/16/32/64/128 in binary. In Fig. B: Binary start, schedule No. 13 is
selected since signals SCH1/4/8 are determined.
In 6) and 7), a schedule of the smallest number among input schedule signals
SCH1/2/4/8/16/32/64/128 can be used. In Fig. C: 8 single signal start, the
smallest schedule No. 1 is selected since signals SCH1/4/8 are determined.
(c) END SIGNAL TIME
Set the length of time for output of the end signal. The output time can be set in
a range from 10 to 200 ms and in units of 10 ms. Setting 0 ms switches to
HOLD and maintains the end signal output during the start input.
When OFF is set, actually output END time changes depending on the OFF
setting even if a value is set for END SIGNAL TIME. (See below.) Also, this is
not output depending on the END SIGNAL MODE setting.
END SIGNAL TIME is 0
ms.
1) OFF time is 0
ms. (OFF time = 0
ms)
a) When the start input time is longer than the sequence time, the end
signal time is the start input time. (Sequence time ≤ start input time →
END time = start input time)
b) When the start input time is shorter than the sequence time, the end
signal time is the 10
ms. (Sequence time > start input time → END time
= 10
ms)
2) OFF time is 10
ms to 200
ms. (10
ms ≤ OFF time ≤ 200
ms)
End signal time is the set OFF time. (END time = OFF time)
3) OFF time is 200
ms or more. (OFF time > 200
ms)
End signal time is the 200
ms. (END time = 200
ms)
END SIGNAL TIME is 10 to 200
ms.
1) OFF time is 0
ms. (OFF time = 0ms)
End signal time is the set END SIGNAL TIME time. (END time = END
SIGNAL TIME time)
2) OFF time is set (10
ms ≤ OFF time)
a) END SIGNAL TIME time is shorter than OFF time. (END SIGNAL TIME
time < OFF time)
End signal time is the set END SIGNAL TIME time. (END time = END
SIGNAL TIME time)
b) END SIGNAL TIME time is equal to or longer than OFF time. (END
SIGNAL TIME time ≥ OFF time)
End signal time is the OFF time. (END time = OFF time)
(d) END SIGNAL MODE
Set the conditions for output of the end signal upon completion of the weld
sequence.
0: Outputs the end signal even when the monitored value is outside the upper
and lower tolerance limits. The end signal will not be output in the event of
an error or when the sequence is interrupted by START SIGNAL MODE
(MAINTAINED).
1: The end signal will not be output when the monitored value is outside the
upper and lower tolerance limits(*), in the event of an error, or when the
sequence is interrupted by START SIGNAL MODE (MAINTAINED).
2: The end signal will be output even when the monitored value is outside the
upper and lower tolerance limits(*), even in the event of an error, and even
when the sequence is interrupted by START SIGNAL MODE (MAINTAINED).
