I'm having trouble programming a PID loop in 505 workshop. Are there any examples out there of how to program this, or how it even works? I got a document that was made by Siemens explaining everything, but it doesn't really show examples.
My application is a conveyor belt feeding material into a crusher. The belt is run by a VFD (reading frequency) and the crusher is run by a 40A soft starter (reading current). We want to be able to set a setpoint current and have the belt speed up/slow down to maintain this current. The higher the current, the lower the frequency, and vice-versa.
