14.32 Circular Feed in Manual Mode

14.32.1 Outline

By specifying a hypothetical coordinate on the machine coordinate system from the user PLC, oblique linear interpolation or
circular interpolation is executed with jog feed, handle feed, manual rapid traverse or incremental feed of the two axes
designated by plane selection. When a rotary axis is specified, the operation is ignored.
In this chapter, the horizontal axis is described as "H axis" and the vertical axis is as "V axis".
H axis and V axis are determined by setting values of the following parameters and R registers.
 "#1026 base_I" (Base axis I)
 "#1027 base_J" (Base axis J)
 "#1028 base_K" (Base axis K)
 R2636 bitE, bitF (plane selection mode)

When the circular feed in manual mode (oblique linear interpolation) is valid:
- Jog/handle feed of H axis results in the movement in parallel with H' axis (see above).
- Jog/handle feed of V axis results in the movement in parallel with V' axis (see above).
a: Gradient angle
h, v: Reference point coordinate
±h': H' travel range
±v': V' travel range
These are set in the R registers.
