50 Operations
The pulses output from X or Y axis remains 1/2 pulse difference
according to a perfect linear line. The precision of linear interpola-
tion is shown as below:
If users want to stop an interpolation group, just call a stop func-
tion on first axis of the group.
As in the diagram below, 2-axis linear interpolation means to move
the XY position from P0 to P1. The 2 axes start and stop simulta-
neously, and the path is a straight line.
The speed ratio along X-axis and Y-axis is (
Δ
X:
Δ
Y), respectively,
and the vector speed is:
When calling 2-axis linear interpolation functions, the vector speed
needs to define the start velocity, StrVel, and maximum velocity,
MaxVel.
4.2.8 Two Axes Circular Interpolation Mode
Circular interpolation means XY axes simultaneously start from ini-
tial point, (0,0) and stop at end point,(1800,600). The path
