Radius is the arc radius in counts (servo axes) or steps (stepper axes). The range is 2 to (2^31) ±1 counts (steps).
Start angle is the double precision floating point value in degrees of the starting angle of the arc. The range is 0 to 360° where angle 0 is along the positive X axis and values increase counter-clockwise from the positive X axis in the X-Y plane.
Travel angle is the double precision floating point value in degrees of the angle to be traversed. The range is -1,474,560 to +1,474,200° (-4,096 to +4,095 revolutions). A positive Travel Angle defines counter-clockwise rotation in the X-Y plane.
Components of a circular move.
