WHEN MAINTAINED. If the
2ND STAGE
signal stops halfway through the welding
sequence (from the beginning of initial squeeze delay time through the end of hold time),
the welding sequence will halt at that point.
NOTE: The
END
signal depends on the
END SIG.MODE
setting.

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 200ms and in units of 10ms. Setting 0ms 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 SIG.TIME (see below). Also, this is not output
depending on the END SIGNAL MODE setting.
EXAMPLE:
END SIGNAL TIME is 0ms
1) OFF is 0ms (OFF time = 0ms)
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
10ms. Sequence time > start input time
→
END time = 10ms)
2)
OFF time is 10ms to 200ms (10ms ≤
OFF
time ≤ 200ms)
. End signal time is the set OFF
time ( END time = OFF time).
3) OFF time is 200ms or more ( OFF time > 200ms). End signal time is the 200ms. ( END
time = 200ms).
EXAMPLE:
END SIGNAL TIME is 10 to 200ms
1)
OFF
is 0ms (
OFF
time = 0ms). End signal time is the set
END SIG.TIME
time. (
END
time
= END SIG.TIME time).
(depends on the END SIG.MODE setting if the welding
sequence is halted)
