How to write a motion program use a different Acceleration and Deceleration’s Ts
#1
We want the load to move from A to B then to A like this picture.How to write a progam to realize it?
The area of trapezoid is equal too. And they have different Ts.

Your image did not come through. But it is easy to do what you want to do. You just need to specify the deceleration time AFTER the acceleration time (because specifying the acceleration time changes both accel and decal). For example:

F20
ta100
td200
x10

You can click the picture, then it will show all. They have different Ts. How to define them

Now I can see the picture -- I don't know why I could not before.

The idea is the same as I suggested before, but including different "S-curve" times (the velocity profile is S-shaped).

For example:

F20
ta100 ts50 // ta+ts = t1
td200 tsd25 // td+tsd = t2
X100

Remember that if you want separate deceleration times, you must specify them AFTER specifying the acceleration times.
