WELD2 STOP/WELD COUNT is WELD COUNT
A count error signal is output if the number of welds deposited while the external weld count
signal is input is smaller than the value set for
PRESET COUNT
(weld count signal is turned off
before the number of welds set for
PRESET COUNT
is not deposited). See the following
diagram.
For example, if you set the number of welds to 5 from the programmable logic controller, select
“
5
” for
PRESET COUNT
as well.
This function can be turned on or off through
WELD2 STOP/WELD COUNT
on the
MODE
SELECT
screen. To clear the count error signal, you need to input the weld count signal again
or add required number of welds to make up for insufficiency. The count error signal is not
cleared if the error reset signal is input. Also, when required number of welds are added to make
up for insufficiency, the count error signal is output until the insufficient number of welds is
complete.
