I am new to programming. I have an application that I am working on that I would appreciate some help with. The idea is to speed up and slow down a VFD at a predetermined footage increment. For example, the operator would set the limits of this increment on the HMI, say 9'' to 10''. Now the motor would start to ramp up starting at 9'' and reach max at 10'' then ramp down to 9'' again. Then repeat. Also I would like to display the ramp progress on the HMI. Would there be a particular function block that I could use for this? Any help with this would be greatly appreciated.
