LGB APPLICATION
An order requires that sheets of material be cut in two different lengths. The operator would like to change the settings for the second length
to be cut with no down time. A Legend series LGB (Four Preset Batch Counter/Rate Indicator) is used to satisfy the requirement.
A Lenght Sensor (LSQ) with a 100 pulse per revolution (PPR) quadrature output is coupled with an LSAHC hinge clamp assemby and a
one foot circumference wheel. The LEGEND series LGB is set to the Quadrature X1 mode. With a one foot wheel, the information becomes
100pulses/foot and allows the material to be cut to the nearest 1/100 of a foot. The counter display is programmed for two decimal places to
provide a readout in 1/100 of a foot increments.
Preset value P
1
(Process count) is
programmed for the first length to
be cut for the order and Preset value
P
2
(Process count) for the second
length.
The outputs are used to control
power to the cutting knife and the
counter is programmed to reset
when Preset 1 or Preset 2 is reached.
Preset value P
3
(Batch count) is
programmed to activate User Input 1
(skip P
1
) when the total number of
pieces is reached for the first order.
Preset value P
4
(Batch count) is
programmed to stop the process
after the second order is complete.
The totalizer will keep track of the
total amount of feet used.
