I am working on a converting machine that is direct driven thru magnetic clutch to regulate tension on the final shaft. The new machines use a servo drive to control this shaft I am considering changing our older machines to this type of system. What it needs to do is keep a constant tension between this shaft and the rest of the machine. i am looking for the easiest cheapest way to do this. The simpler the controls the better. It is being done with a simple pot controlling the voltage to the clutch. i would like it to be a close to this from the operator standpoint as possible. The machines are being controlled by a step-7 200 plc ranging from a 214 to a 226 cpu. Any ideas on a simple system for this??
