Hi to all. I want to write code to position control of a single axis in the PLC. The drive is velocity-controller axes with position feedback in quadrature encoder.

What I need is (I think) the softmotion library and a pid FB.

My question is: since all the softmotion and pid code is in application level, what appen when the application stop or my application code have a breakpoint? Does the axis begin uncontrolled? and can run over softlimits. ?

Is there the possibility to run softmotion and pid in special task that run Always?

thanks
Giuliano
