CR (Circle)

[Motion]

DESCRIPTION:

The CR command specifies a 2-dimensional arc segment of radius, r, starting at angle,

θ, and traversing

over angle

∆θ. A positive ∆θ denotes counter clockwise traverse, negative ∆θ denotes clockwise. The

VE

(Vector Sequence End)

command must be used to denote the end of the motion sequence after all CR and

VP (Vector Position)

segments are specified. The

BG (Begin)

command is used to start the motion

sequence. All parameters, r,

θ, ∆θ, must be specified. Radius units are in quadrature counts. θ and ∆θ have

units of degrees. The parameter n is optional and describes the vector speed that is attached to the motion
segment.

ARGUMENTS: CR r,

θ,∆θ<n>o

where

r is an unsigned real number in the range 10 to 6000000 decimal (radius)

θ a signed number in the range 0 to +/-32000 decimal (starting angle in degrees)
∆θ 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 12,000,000 for servo motor operation and between 0 and 3,000,000 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 *

∆θ must be limited to +/-4.5 * 10
