MD-A series
・
1-step welding
(When SCHEDULE MODE on the STATUS screen is set to SINGLE)
Remarks
SQ: Squeeze time
RC: Precheck weld time
CP: Precheck judgment time (2 ms) UP: Upslope time
WE: Weld time
DS: Downslope time
HD: Hold time
*1: For the timing of schedule select signal and start signal, refer to
3
External input signal
.
*2: When a fault or caution occurs in precheck welding, welding is not
performed in WE and the fault signal or the caution signal is output.
The selection of fault signal or caution signal can be changed on the
ERROR SETTING screen. At this time, the end signal and the normal
signal are not output.
*3: Monitor calculation time (10 ms)
*4: For the output time of end signal and normal signal, refer to
4
External output signal
. For the processing time of screen display
time, communication output time, etc., refer to
5
Screen display and
communication time
.
*5: When the monitor value is within the setting range, the normal signal is
output. When the monitor value is outside the range or a fault occurs,
a fault signal or caution signal is output. The selection of fault signal or
caution signal can be changed on the ERROR SETTING screen.
*6: The weld force signal cannot be controlled with this device. Control it
by PLC or the like. For the timing of weld force, refer to
6
Weld force
