Applying drive specifications to systems applications. III. Position regulation

In web/strip processing lines, position loops are used to regulate dancers, accumulators, cutting shears and for motion or positioning control in many other applications. Depending on the requirements of the application, a fast responsive torque regulator may or may not be required. This paper provides guidelines for the useful interpretation of AC/DC motor drive performance specifications as applied to positioning applications, from a drive system´s application perspective.
