It does indeed but my arms, hands and feet are tied. I am in the the real world where the things you would do because it makes sense are not allowed because of non-sense. So I trudged. and I have it working to some degree now ... but .. it could have been easier...

I really hate to fudge numbers as a guess of how much difference in RPM to trim. I know my payoff speed, my take-up speed, my ratio's for both torque and rpm - what they should be at tension SP and also what they are at process value. In a perfect world - where I follow at x speed , to vary...

1: Maintain a given tension in the material on the takeup reel? YES. 2: It is a web, imagine a long roll of paper threaded down a machine.. 3: Supply enough RPM's to the motor to maintain feed rate and also provide a constant tension on the take-up roll. The feed rate is what is being provided...

I am not trying to be insulting - my apologies - I have just read about 100 different documents (maybe that is an under estimate) in the last 5 days and each one once it comes to load cell tension control - they all stop and declare the controller then controls the tension - no formulas of how...

I have that document already and many more like it : See page 11 of 52 - you will note all of those WONDERFUL formulas for all of the methods Prior to ; and then on that page 11 ... a load cell provides feedback to a controlling module .. ..now what is the formula to provide that feedback in...

I had difficulty in replying , I don't know what happened .. feed forward is being used - this will be my tension RPM value. PIDE Loop in PLC will control the motor. It is a web not a rope - but basically the same.. So I know I can calculate Horsepower at x Diameter, n FPM, T tension and Build...

In a web tension control system, where feed forward is to be used. A tension set point is desired let's say 20lbs, and a load cell system provides feed back. There will be dead weight on the load cell as the material with no pull sits on top of the load cell system. [Obviously I will need to...
