4. Motion Control Instructions
DVP-MC operating manual 4-207
A_Pos
The coordinate position of terminal point of the
added axis
REAL Constant, D
B_Pos
The coordinate position of terminal point of the
added axis
REAL Constant, D
C_Pos
The coordinate position of terminal point of the
added axis
REAL Constant, D
P_Pos
The coordinate position of terminal point of the
added axis
REAL Constant, D
Q_Pos
The coordinate position of terminal point of the
added axis
REAL Constant, D
R_Value
The radius of the circular arc. Positive number is
minor arc and negative number is major arc.
REAL Constant, D
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
GroupID
The number of the coordinate motion instruction
group, range: 0~7.
When the instruction is executed, the group ID
should be consistent with that of DNC_Group.
UINT Constant, D
Done
When the execution of the instruction is finished,
“Done” is on; when “Execute”
turns off, “Done” is reset.
BOOL M,Q
Error
If any error is detected, "Error" turns on; when
"Execute" turns off, "Error" is reset.
BOOL M,Q
ErrorID Error code. Please refer to section 5.3. UINT D
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 axis related with 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.
