Cx : X-axis (first axis of target axes) absolute position of center of

arc

Cy: Y-axis (second axis of target axes) absolute position of center

of arc

Ex: X-axis (first axis of target axes) absolute position of end of arc

Ey: Y-axis (second axis of target axes) absolute position of end of

arc

CW_CCW: Specified direction of arc

StrVel: Starting velocity of a velocity profile in units of pulse per

second.

MaxVel: Maximum velocity in units of pulse per second.

Tacc: Specified acceleration time in units of seconds.

Tdec: Specified deceleration time in units of seconds.

SVacc: Specified velocity interval in which S-curve acceleration is

performed.

Note: SVacc = 0, for pure S-Curve. For more details, see sec-

tion 4.2.4

SVdec: specified velocity interval in which S-curve deceleration is

performed.

Note: SVdec = 0, for pure S-Curve. For more details, see sec-

tion 4.2.4

*AxisArray: Array of axis number to perform interpolation.

Example: I16 AxisArray[2] = {0, 3}; //axis 0, & axis 3 (correct)

I16 AxisArray[2] = {1, 6}; //axis 1, & axis 6 (incorrect)

*OffsetCenter: Array of the offset to center (relative to the start

position)

Example: F64 OffsetCenter[2] = {2000.0, 0.0}; //offset from

start position(initial point) for 1st & 2nd axes
