You have a condition where your code gets blocked due to the improper use of the event structure. You have a second event structure where the value of thespeed or current indicators change, then that case gets run. But since they are indicators, the only place where they get changed is inside that event case themselves.
Also, the value change event doesn't get fired if you write to a terminal, local variable, or Value property node of a control or indicator. It only gets fired if you write to the Value (signalling) property node or the user changes the value on the front screen. Generally, the event structure is used to handle user events such as changing a control, so it doesn't make much sense in most cases to have an event based on an indicator.
I'm not sure why you are using an event structure in either loop. The event structure in the first loop incorporates a bad programming practice. You have an event based on a control that has no name. By looking at the code, I can't tell what control would fire the value change event since the name of the control is empty.
