General Codes (F, N, Q, X, Y, Z, A, B, C)

F

F<v>

Set velocity to v. Applies to the current block and all succeeding blocks until a new velocity is programmed. The unit for velocity selected currently is used. (See section unitVelocitySet for details.) The default velocity is 0.

The velocity must be set to a nonzero value before a movement is programmed. Otherwise, an error is issued.

Example:

The first two segments N10 and N20 are processed with a velocity of 6000 mm/min, and the last segment N30 is processed with a velocity of 3000 mm/min.

N10 G01 X100 F6000
N20 G01 X200
N30 G01 X300 F3000
M02

N

N<v>

Set the block number to v. Typically, the block number is used to monitor the progress of the NC-program.

Q

Q<i>=<v>

Set the value of axis Q<i> to v where i must lie in the range 1 to 5. The Q-axes use linear interpolation.

The address letters Q and R are handled in a special way for historical reasons.

The address Q<i> has to be followed by a G-expression or by an ST-expression. The G-word Q1100 is invalid. Use Q1=100, instead.

Example:

The path of the following example is shown in Figure “ExampleQ”. The Q-axes are interpolated linear with the interpolation of a movement. The last block (N40) results in a linear interpolation of a Q-axis without a concurrent movement.

N10 G01 X30 Y0 Q1=100 F6000
N20 G02 X50 Y20 I20 Q2=200
N30 G01 X60 Q1=300 Q2=300
N40 Q1=0
M02

X

X<v>

Sets the X-coordinate of the next point to v. The current length unit is used for v.

Y

Y<v>

Sets the Y-coordinate of the next point to v. The current length unit is used for v.

Z

Z<v>

Sets the Z-coordinate of the next point to v. The current length unit is used for v.

A

A<v>

Sets the A-angle of the next orientation to v. The current angle unit is used for v.

B

B<v>

Sets the B-angle of the next orientation to v. For v the current angle unit is used.

C

C<v>

Sets the C-angle of the next orientation to v. For v the current angle unit is used.
