In the rmc150，Sine Start (72) can Achieve sina profile control for one axis.
How to implement two axes sina trajectory control？curves or other？

What exactly do you mean by two-axis sine trajectory control?

Two axes move, forming a sine profile。
Unlike Sine Start (72) Achieve sina profile control only using one axis。

Do you mean 2 axes in a cartesian coordinate system? I think curves is the best way to do that.

Yes。
I want to know that, In order to ensure control Accuracy, the 2 axes need to be in different task。
Is is ok? in different task are better than in the same task,because one task can only run one program in the same time.

It is important to know that user programs are not necessarily connected to axes. User programs are basically a list of commands to send to the axes. You only need one user program. That user program can send commands to both axes. To do a curve on a 2-dimensional Cartesian coordinate system, use two curves and run then at the same time. The user program only needs to send the two Curve Start commands simultaneously, then the user program is done.
