When the time comes where the drive system that has been operating on a paper machine or winder becomes old and difficult to maintain, the user is forced to look for an alternative that will solve the immediate problems and minimize the capital outlay. Rebuilds are typically selected when cost is the major concern because of the lower initial cost. Regardless of whether the system is completely new or a rebuild, the overall equipment package needs to provide the use with a better source for parts, enhanced diagnostics and increased reliability. This "new" drive system does not always mean that everything is new. Budgetary constraints may prevent a complete full scale replacement. It may involve replacing the old drive power structure and controller, while maintaining as many of the motor and power circuit wiring as possible.
