1 Spot Welding Application Using a Motor Gun
1.4 System Setting (Motor Gun)
15. WELD COMPLETE OFF WAIT TIME
When "14. WELD COMPLETE DETECT METHOD" is "STATUS", set-
ting becomes valid.
The controller waits for the setting time until the weld complete signal is
turned OFF if it is already turned ON at beginning of the welding instruc-
tion. If the weld complete signal is not turned OFF after passing the set-
ting time, an alarm occurs.
16. WEAR WARNING VALUE (UPPER)
17. WEAR WARNING VALUE (LOWER)
Outputs the pulse (pulse time length for 500msec) of the wear detection
error signal (specified output #51535) when the wear value is more than
the setting value.
Becomes invalid when "0" is set.
18. WEAR MINUS THRESHOLD (UPPER)
19. WEAR MINUS THERSHOLD (LOWER)
Outputs the pulse (pulse time length for 500msec) of the wear detection
error signal (specified output #51534) when the wear value is less than
the setting value.
Becomes invalid when "0" is set.
20. WEAR DIFFERENT THRESHOLD (UPPER)
21. WEAR DIFFERENT THRESHOLD (LOWER)
Outputs the pulse (pulse time length for 500msec) of the wear detection
error signal (specified output #51534) when the difference between the
wear value from the last time and the current value is more than the set-
ting value.
22. WEAR POS. THRSHLD AFTER CHG (UP)
23. WEAR POS. THRSHLD AFTER CHG (LOW)
24. WEAR NEG. THRSHLD AFTER CHG (UP)
25. WEAR NEG. THRSHLD AFTER CHG (LOW)
If performing the wear detection while the tip change signal (specified
input #41135) is turned ON, the wear value is compared with the set
threshold value. Outputs the pulse (pulse time length for 500msec) of
the wear detection error signal (specified output #51534) when the wear
value is out of the threshold range.
26. ERROR DISP TYPE
Set the indication type to show an alarm when the alarm occurs by the
NADEX welder side.
Select from the two types below.
DISP ALARM: Displays the alarm.
DISP MESSAGE: Displays the message.
27. ALARM SIGNAL SELECT BIT (WELD1)
The items are shown according to the set numbers in the "2.MAX NUM-
BER OF WELDER CONNECT".
Specify the signal by a bit (up to 16-bit) which is used as alarm signals
among the signals from the NADEX welder when NADEX welder gener-
ates an alarm.
