・
STEPPER (step-up (-down) operation)
When the 1ST STAGE signal is input, VALVE 1 is output, and then SOL2 is output after SQD.
After SQD and SQZ, the sequence waits for the 2ND STAGE signal input. Next, when the 2ND
STAGE signal is input, the welding sequence after WELD1 starts.

n. MONITOR DISP MODE
Sets the monitor display. This function is invalid when the Pendant is disconnected.
NORMAL
The monitor display is updated each time. It takes monitored
value computing time + display time (ms). Used when the part
cycle time is relatively slow.
* Communicated with the Pendant each time welding is complete.
LAST
The monitor display is not updated. When the MONITOR screen
is updated, the last measured value is displayed. Used when the
part cycle time is relatively fast.
Errors are also displayed only when updated (communicated with
the Pendant).
* Not communicated with the Pendant automatically.
o. RE-WELD
Select whether or not to supply welding current again
at the same location if the monitored current is lower
than the lower limit. The second welding current will
be 5% greater than the setting value.
Even when the welding current is supplied twice with RE-ELD, each count-up is done only once.
