b. WELD STOP INPUT
Select items for weld stop.
OFF : External Input, WE1 to WE3 Stop Input are effective.
DISPLC : Weld Stop works at the set displacement value.
CURR : Weld Stop works at the set current value.
VOLT : Weld Stop works at the set voltage value.
POWER : Weld Stop works at the set power value.
PULSE : Weld Stop works at the set pulse width.
c. WELD STOP CONDITION
Set values for items selected in WELD STOP INPUT .
OFF : Not displayed.
DISPLC : Set the value of displacement.
CURR : Set current value.
VOLT : Set voltage value.
POWER : Set power value.
PULSE : Set pulse width.
d. WORK DETECT LIMIT
e. WORK DETECT MONITOR
The presence or absence of work piece can be detected by measuring the head travel distance
from the beginning of SQD through the end of SQZ. The presence or absence and overlapping
of work piece can be detected.
In WORK DETECT LIMIT , set the upper limit (HIGH) and the lower limit (LOW) in
consideration of the difference between the head travel distance from the beginning of SQD
through the end of SQZ and the presence or absence of a work piece to detect.
In WORK DETECT MONITOR , the measured value of the head travel distance from the
beginning of SQD through the end of SQZ at welding is displayed.
In WORK DETECT LIMIT , you can set a value checking the measured value of work piece
detection when the head is actually operated.
To use the work piece detection function, the used displacement gauge should be ready at any
time to measure the displacement from force releasing to force applying (the measurement range
of the displacement gauge is larger than distance between electrodes at force releasing).
Otherwise, the work piece detection will not be done properly.
