PCI1040 Motion Control Card
Fig.2.5 Symmetrical S-shaped Acceleration/Deceleration Driving
3.3 Interpolation
This 8-axis motion control card can perform any 2, 3, 4 axes linear interpolation. In the process of interpolation
driving, all the calculations will follow the main axis (ax1). So, the user has to set the parameters such as initial
speed and drive speed of the main axis before performing the interpolation. During the linear interpolation, it is
not necessary to set the main axis as “long axis”.
Axes #1 to #4 of the 8 axes can be set for linear interpolation. To execute the linear interpolation, the user can,
according to the present point coordinates, set the finish point coordinates. Fig.2.6 shows an example of axis
interpolation where linear interpolation is performed from the current coordinates to the finish point coordinates.
For individual axis control, the command pulse number is unsigned, and it is controlled by +direction command
or –direction command. For interpolation control, the command pulse number is signed. The resolution of linear
interpolation is within
±0.5 LSB, as shown in Fig.2.6.
