4. Motion Control Instructions Note: 1. The function of the instruction DNC_CW(R) (G2) and DNC_CCW(R) (G3) is same as that of G2 and G3 in G codes and the input parameters X_Pos~Deceleration in the instruction and the parameters of X_, Y_, Z_, A_, B_, C_, P_, Q_, R_,T_, F_,E_,E_ in G2 and G3 have same explanation. For more details on G2 and G3, please refer to section 4.8.3.5. 2. The state of axes related to the instruction is Standstill. After “DNC_Group” is executed, the instruction just can be executed and its GroupID must be same as that of DNC_Group. 3. The instruction can be switched to absolute mode via DNC_Absolute (90).
In absolute mode, the terminal position of each axis is based on 0 unit. 4. The instruction can be switched to relative mode via DNC_Relative (91). In relative mode, the terminal position of each axis is calculated as incremental value beginning from current position. 5. It is absolute mode for the instruction by default. Therefore, it is absolute mode for DNC_CW (R) (G2) and DNC_CCW(R) (G3) if DNC_Absolute (90) and DNC_Relative (91) have not been executed.

Positive number is REAL Constant, D R Value _ minor arc and negative number is major arc.
T Value _ The quantity of the full circle UINT Constant, D Velocity The feed speed of the circular arc REAL Constant, D Acceleration Acceleration REAL Constant, D Deceleration Deceleration REAL Constant, D The number of the coordinate motion instruction UINT Constant, D group, range: 0~7. GroupID When the instruction is executed, the group ID should be consistent with that of DNC Group. _ When the execution of the instruction is finished, BOOL M,Q Done “Done” is on; when “Execute” turns off, “Done” is reset. If any error is detected, "Error" turns on; when BOOL M,Q Error "Execute" turns off, "Error" is reset. ErrorID Error code. Please refer to section 5.3. UINT D
