The programmable controller is not used in this example.
Each time the sheet material
is
cut by the cutter, the table is lowered by the same amount as
the thickness
of
the cut material.
When the sheet material cut reaches the desired number
of
sheets, the operation is com-
pleted, and the material on the table is removed by other means.
In this case, the take-out confirmation switch
X4
is actuated.
It is possible to interlock the operation with the PGU-1 shown in application example
(1)
by
using the general-purpose outputs
Y3,
Y4,
and
Y6
(see the next page.).
