➌ Cen_X item: Center's x-coordinate. API function's argument variable
“arc3_cen_x”.
Cen_Y
item: Center's y-coordinate. API function's argument variable
“arc3_cen_y”.
End_X item: Endpoint's x-coordinate. API function's argument variable
“arc3_end_x”.
End_Y item: Endpoint's Y-coordinate. API function's argument variable
“arc3_end_y”.
Dir item: Direction. API function's argument variable “arc3_dir”.
When this value is 0, the servo motor will rotate clockwise (CW).
When this value is 1, the servo motor will counterclockwise (CCW).
5) Set Servo Motor Power ON/OFF(servo on/servo off)

Click on the “SVON” button to execute the following procedure:
rt = _DMC_01_ipo_set_svon(gDMCCardNo, NodeID, SlotID , ON_OFF);
// ON_OFF: 0 – Servo Power OFF; 1 – Servo Power ON
6) Start 2-axis arc interpolation motion control
Click on the “” or ““ button to execute the following procedure:
2-axis arc interpolation using interpolation method 1 (Arc1):
rt = _DMC_01_start_sa_arc_xy(gDMCCardNo, gArcNode, gSlot2, arc1_cen_x,
arc1_cen_y, arc1_angle, StrVel, MaxVel, acc, dec);
// Arc interpolation motion using absolute coordinates under the S-curve velocity
cross-section
rt = _DMC_01_start_ta_arc_xy(gDMCCardNo, gArcNode, gSlot2, arc1_cen_x,
arc1_cen_y, arc1_angle, StrVel, MaxVel, acc, dec);
// Arc interpolation motion using absolute coordinates under the T-curve velocity
cross-section
rt = _DMC_01_start_sr_arc_xy(gDMCCardNo, gArcNode, gSlot2, arc1_cen_x,
arc1_cen_y,
arc1_angle, StrVel, MaxVel, acc, dec);
// Arc interpolation motion using relative coordinates under the S-curve velocity
cross-section
rt = _DMC_01_start_tr_arc_xy(gDMCCardNo, gArcNode, gSlot2, arc1_cen_x,
arc1_cen_y, arc1_angle, StrVel, MaxVel, acc, dec);
// Arc interpolation motion using relative coordinates under the T-curve velocity
