4. Motion Control Instructions
4-174 DVP-MC operating manual
¾ Parameter explanation:
N_: The row number of G code in NC program
X_: Specify the terminal position of axis X, Unit: unit, data type: REAL.
Y_: Specify the terminal position of axis Y, Unit: unit, data type: REAL.
Z_: Specify the terminal position of axis Z, Unit: unit, data type: REAL.
A_: Specify the terminal position of axis A, Unit: unit, data type: REAL.
B_: Specify the terminal position of axis B, Unit: unit, data type: REAL.
C_: Specify the terminal position of axis C, Unit: unit, data type: REAL.
P_: Specify the terminal position of axis P, Unit: unit, data type: REAL.
Q_: Specify the terminal position of axis Q, Unit: unit, data type: REAL.
E_: Specify the acceleration and deceleration of the cutter. The positive number refers to the
acceleration; the negative number refers to the deceleration, unit: unit/second2, data type: REAL.If
only the acceleration is specified, the deceleration is decided by the maximum deceleration in
axis X parameter; If only the deceleration is specified, the acceleration is decided by the
maximum acceleration in axis X parameter.
F: Specify the feed speed of the cutter, unit: unit/second, data type: REAL.When the cutter moves at a
constant speed, the combined speed of all axes in G code is equal to F value. The method of
calculation is shown below.
When two axes exist,
22
12
FVV=+.
When three axes exist,
222
123
F
VVV=++
.
For more axes, F value could be calculated in the same way as above.
¾ Instruction explanation:
G1 can control one or more axes and other axis can be omitted.
Both of E and F can be omitted. If there is only one row of code in the CNC programming area and
E, F are omitted, the velocity, acceleration, deceleration are decided by the parameters of X axis,
i.e. maximum velocity, maximum acceleration, maximum deceleration in the
parameters of X axis.
If there are multiple rows of codes and E and F in G1 code are omitted, the velocity, acceleration,
deceleration of the cutter are based on E and F in the previous rows of codes before the row where
G2 is. If the previous rows of G codes have not specified E and F, maximum velocity,
maximum acceleration, maximum deceleration in the parameters of X axis will be taken
as reference.
Absolute mode decided by G90: The terminal position of G1 is based on 0 unit.
Relative mode decided by G91: The terminal position of G1 is an incremental value beginning from
the current position.
y Absolute mode example:
The initial positions of axis X, Y, Z are all 20000 units and their axis parameters are all default
value. The G codes to be executed are:
N0 G90
N1 G1 X50000 Y60000 Z70000
After G codes are executed, the Y/X curve for the whole movement process is shown below:
