LGM APPLICATION
A process performs five different procedures to a piece of raw stock at five different locations. The Legend series LGM with six presets
and six solid state outputs is used for this application.
The raw stock comes in ten foot sections and requires five various operations to be performed at 9.00", 23.00", 72.00", 83.00", & 111.00".
A rotary pulse generator (RPGB) with a 600 pulse per revolution (PPR) quadrature output is coupled to a 1 foot circumference wheel. A
quadrature sensor is specified because the stock must be reversed after stations #1 and #4. This allows the Legend to keep track of true position.
The Legend is set to the quadrature X2 mode
which increases the pulses to 1200 PPR. This gives a
measurement resolution of 1/100 of an inch. The five
Presets are programmed with the proper values and
the solid state outputs control pilot relays that control
the actuators. As the material passes each station, a
signal is sent to the proper equipment and the process
is performed. Also, the outputs are programmed so
that if a power outage occurs they will save the state
that they were in at power down.
The sixth output is assigned to rate so that if the
rate drops below a predetermined value the output
will activate a warning indicator.
