/i
Type Axis command
Syntax CAMBOX(start_point, end_point, table_multiplier, link_distance,
link_axis [ , link_option [ , link_position ]])
Description The CAMBOX command is used to generate movement of an axis following a
position profile in the TABLE variable array. The motion is linked to the meas-
ured motion of another axis to form a continuously variable software gearbox.
The TABLE values are absolute position relative to the starting point and are
specified in encoder edges.
The TABLE array is specified with the TABLE command. The movement can
be defined with any number of points from 3 to the maximum table size avail-
able (500000). Being able to specify the start point allows the TABLE array to
be used to hold more than one profile and/or other information. The TJ2-
MC64 moves continuously between the values in the TABLE to allow a
number of points to define a smooth profile. Two or more CAMBOX com-
mands can be executed simultaneously using the same or overlapping values
in the TABLE array.
Note that CAMBOX command allows traversing the TABLE backwards as
well as forwards depending on the Master axis direction.
The link_option argument can be used to specify different options to start the
command and to specify a continuous CAM. For example, if the link_option
is set to 4 then the CAMBOX operates like a "physical" CAM.
CAMBOX works on the default basis axis (set with BASE) unless AXIS is
used to specify a temporary base axis.
Note: While CAMBOX is being executed, the ENDMOVE parameter will be
set to the end of the previous move. The REMAIN axis parameter will hold the
remainder of the distance on the link axis.
