2-31
Terminal name
Explanation
18.WEL2 UPPER
CURRENT
When the measured current waveform of the second welding exceeds the
upper limit of the judgment current value, this signal is output for the 02. NG
signal setting time.
19.WEL2 LOWER
VOLTAGE
When the measured voltage value of the second welding is lower than the
lower limit of the judgment voltage value, this signal is output for the 02. NG
signal setting time.
20.WEL2 UPPER
VOLTAGE
When the measured voltage value of the second welding exceeds the lower
limit of the judgment voltage value, this signal is output for the 02. NG signal
setting time.
21.WEL2 LOWER
TIME
When the second welding is lower than the lower limit of the judgment time, this
signal is output for the 02. NG signal setting time.
22.WEL2 UPPER
TIME
When the second welding exceeds the upper limit of the judgment time, this
signal is output for the 02. NG signal setting time.
23.WEL2 LOWER
ENVELOPE CUR
When the measured current waveform of the second welding is lower than the
lower limit of the judgment current waveform, this signal is output for the 02.
NG signal setting time.
24.WEL2 UPPER
ENVELOPE CUR
When the measured current waveform of the second welding exceeds the
upper limit of the judgment current waveform, this signal is output for the 02.
NG signal setting time.
25.WEL2 LOWER
ENVELOPE VLT
When the measured voltage waveform of the second welding is lower than the
lower limit of the judgment voltage waveform, this signal is output for the 02.
NG signal setting time.
26.WEL2 UPPER
ENVELOPE VLT
When the measured current waveform of the second welding exceeds the
upper limit of the judgment current waveform, this signal is output for the 02.
NG signal setting time.
27.SYNC. OUT
This signal is output in the period from the pre-flow output to the end of the
welding.
28.WIRE START
The brazing wire fed signal is output concurrently with a start of the main
welding.
29.H-READY
This signal is output synchronously with the READY signal of the optional head
controller. (*3)
30.H-ST1
This signal is output synchronously with the ST1 signal of the optional head
controller.
Turned on for the time set in “START signal input delay time.” (*3) (*5)
31.H-ST2
This signal is output synchronously with the ST2 signal of the optional head
controller. (*3)
32.H-ERROR
This signal is output synchronously with the ERROR signal of the optional head
controller. (*3)
33.H-HEAD UP
This signal is output synchronously with the H-HEAD UP signal of the optional
input/output. (*3)
34.H-MODE
This signal is output synchronously with the H-MODE signal of the optional
input/output. (*3)
35.MID POINT (*4)
This signal is output synchronously with the MID POINT signal of the optional
head controller. (*3)
*1: The conditions that the READY signal is not output are as follows.
- When an error occurs.
- During the welding sequence.
- When the START input (operation panel and external input) is closed.
- The WELD STOP of the external input is closed.
