A.4 Pulse Output Commands
A.4.1 2-Axes Interpolation
The I-8092F 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 and the interpolation
command(s), as shows in Fig. A-22. 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. We define the longest distance movement in interpolation is the "long axis". And the other is
"short axis". The long axis outputs an average pulse train. The driving pulse of the short axis
depends on the long axis and the relationship of the two axes. The range for each axis is a 24-bit
signed counter, from -2
When performing the linear interpolation, the following parameters should be preset.
Range: R
Initial Speed: SV (PPS)
Driving Speed: V (PPS)
Acceleration: A (PPS/Sec)
Acceleration rate:K(PPS/Sec
