Example A pair of rollers feeds plastic film into a machine. The feed is synchro-
nised to a master encoder and is activated when the master reaches a
position held in the variable start. This example uses the table points
0...30 generated in the example above:
start=1000
FORWARD AXIS(1)
WHILE IN(2)=OFF
CAMBOX(0,30,800,80,15,2,start)
WA(10)
WAIT UNTIL MTYPE=0 OR IN(2)=ON
WEND
CANCEL
CANCEL AXIS(1)
WAIT IDLE
The arguments of the CAMBOX command are:
• 0 is the start of the profile shape in the TABLE
• 30 is the end of the profile shape in the TABLE
• 800 scales the TABLE values. Each CAMBOX motion therefore
totals 800*2000 encoder edges steps.
• 80 is the distance on the product conveyor to link the motion to. The
units for this parameter are the programmed distance units on the
link axis.
• 15 specifies the axis to link to.
• 2 is the link option setting. It means: Start at absolute position on the
link axis.
• The variable start holds a position. The motion will execute when
this position is reached on axis 15.
