Cost Effective Approach to Variable Speed Drive Retrofits, 1996 Process Control, Electrical & Info. Conference Proceedings
Economic and competitive pressures are forcing the pulp and paper industry to improve production efficiency and flexibility. A family of modem microprocessor based modules can be used to retrofit any type of existing drive technology hardware to provide reliable, maintainable, system operation with modem human interface and plant wide communication capability. Creative approaches are available that provide cost effective retrofit upgrades during planned maintenance outages with essentially no down time.
