 FORMAT
I16 PASCAL _DMC_01_start_sr_arc2_xy(U16 CardNo, U16* NodeID,U16* SlotID, I32 End_X,
I32 End_Y, F64 Angle, I32 StrVel, I32 MaxVel, F64 Tacc, F64 Tdec)
 Purpose
2-axis arc interpolation motion using relative coordinates with S-curve velocity cross-section
(Known conditions: endpoint coordinates, angle).
 Parameters
