3 Wire Paper machine, 500mpm(max) uses analogue sectional DC drives & PLC for draw control. It is required to do away with the PLC and speed regulator due to lack of spares. A new PLC will handle draw, HMI, AND speed regulation. Tacho is 300 ppr for 1500rpm motor. Is speed regulation of 0.3mpm achievable? comments,concerns
