Hi,
I use a 9039 cRIO and four NI-9503 modules. With them, I drive step-by-step motors. I use the property and method nodes (Straight-Line-Move) to pass the movement orders. The cRIO also controls the force sensors and the front panel.
My problem is that looping time is too slow. Even by parallelizing the controls, the loop lasts 40 ms.
Depending on how I place these orders on the diagram, the loop time can increase to more than 100 ms. Probably because I lose parallelism.
So, it's impossible to follow a trajectory in these conditions.
What is the problem?
- Is it a bad programming?
- Motors are not suitable?
- What else ?
Thanks to help me.
