be executed on the hypothetical coordinate.
V
v1
v2
When the circular feed in manual mode (circular interpolation) is valid:
- Jog/handle feed of H axis results in the movement along the arc whose radius is the distance from the arc center to
the current position.
- Jog/handle feed of V axis results in the movement on the line connecting the current position and the arc center.
h1, v1: Reference point coordinate
h2, v2: Arc center coordinate
±h': H' travel range
±v': V' travel range
These are set in the R registers.
