ANO*20 Posts: 2 Rating: (0)	Hi Is there a function block for positioning control with analog output, pulse encoder input, and ability to control Jerk and maximum speed (s-curve, s-ramp etc). The output controls speed of DC motor positioning a trolley, but the controller of the DC motor have no intelligence for creating ramps. Any help is appreciated. Regards Johannes
