N10:
Interpolation with rapid traverse
There is an interpolation between the X and Y-axes. The Z-axis follows the X-axis.
The resulting axis velocities are determined in such a way that all axes traverse at
their maximum velocity along a straight line.
N20:
Interpolation with path velocity
There is an interpolation between the X and Y-axes. The partial velocities are
determined for the X and Y-axes. The Z-axis traverses at the velocity of the X-axis.
If the partial velocity calculated for the X-axis is higher than the admissible maximum
velocity (MD31) for the Z-axis, all partical velocities are reduced so far that,
nevertheless, an interpolation straight line can be traversed without violating any axis
velocities.
N30:
Chaining with rapid traverse
The Y-axis traverses with its maximum velocity (MD31). At the same time, the X and
Z-axis traverse with the velocity of the MD31 of the slower axis.
N40:
Chaining with axis velocity
The synchronous axes traverse with the axis velocity FX1000.00 and at the same
time, the Y-axis moves to its position with FY2000.00.
Make sure that in synchronism the axis programmed first determines at the
same time which axis speed is used.
