CR
FUNCTION: Circle
DESCRIPTION:
The CR command specifies a 2-dimensional arc segment of radius, r, starting at angle,
, and
traversing over angle
. A positive denotes counterclockwise traverse, negative
denotes clockwise. The VE command must be used to denote the end of the motion sequence
after all CR and VP segments are specified. The BG (Begin Sequence) command is used to
start the motion sequence. All parameters, r,
, , must be specified. Radius units are in
quadrature counts.
and have units of degrees. The parameter n is optional and
describes the vector speed that is attached to the motion segment.
ARGUMENTS: CR r,
, < n > o
where
r is an unsigned real number in the range 10 to 6000000 decimal (radius)
a signed number in the range 0 to +/-32000 decimal (starting angle in degrees)
is a signed real number in the range 0.0001 to +/-32000 decimal (angle in degrees)
n specifies a vector speed to be taken into effect at the execution of the vector segment. n is an
unsigned even integer between 0 and 22,000,000 for servo motor operation and between 0 and
6,000,000 for stepper motors.
o specifies a vector speed to be achieved at the end of the vector segment. o is an unsigned even
integer between 0 and 8,000,000.
Note: The product r *
must be limited to +/-4.5 108
