3.10 Arc Interpolation Motion Control
3.10.1 Overview
PCI-DMC-A01 supports 2-axis arc interpolation in absolute or relative coordinate
motion modes under the S-curve or T-curve velocity cross-section. Fig. 3.44 illustrates
arc interpolation on any 2 axes.
The start point is P0 (X0, Y0) and end point is P1(X1, Y1). The path from P0 to P1
forms an arc. The maximum velocity is the tangential velocity.
