(3) End, Normal End and Weld End Signals Timing Chart
The output time for End, Normal and Weld End signals depends on the setting for
the End signal output time (HET).
End
signal
Outputs upon completion of the welding sequence.
The output time is the time set for HET (See 9. (2)
).
Normal
signal
Outputs upon completion of the welding sequence when the result of
the upper-lower limit judgment of the monitor function is normal, or no
judgment is made. The output time is the same as that of End signal.
Weld End
signal
Outputs when the stepper-up function is not used.
Output until the End circuit is opened after completion of welding.
Note: When only WELD1 is performed, this is output after completion
of WELD1.
End Signal Output Time (HET) is set to 00
Output for 10 ms or until start signal is turned off, depending on whether the
start signal circuit is opened or closed. It continues to be output as long as the
start signal circuit is closed.
End Signal Output Time (HET) is set to 01
Output for 10 ms whether or not the start signal circuit is open.
