4.2.7 Two Axes Linear Interpolation Position Mode
“Interpolation between multi-axes” means these axes start simul-
taneously, and reach their ending points at the same time. Linear
means the ratio of speed of every axis is a constant value.
Assume that we run a motion from (0,0) to (10,4). The linear inter-
polation results are shown as below.
The pulses output from X or Y axis remains 1/2 pulse difference
according to a perfect linear line. The precision of linear interpo-
laition is shown as below:
If users want to stop an interpolation group, just call a stop func-
tion on first axis of the group.
