Petro-Canada, one of Canada's largest oil and gas companies, chose Eaton to retrofit a competitor's existing motor control centers (MCCs) with new "wrappers" for $150,000, a substantial dollar savings over replacing existing MCC's with new ones. When Petro-Canada began transforming its Rebecca Street facility from a refinery into a distribution center, it asked Eaton and its current MCC supplier for a solution that would enable it to use its existing MCCs and replace FVNR NEMA starters with reduced voltage starters, which could communicate on Modbus TCP/IP to a PLC. The project, at Petro-Canada in Oakville, Ontario: Had minimal available space to replace FVNR (full voltage non-reversing) NEMA starters with reduced voltage starters in the competitor's motor control centers (MCCs); Retrofit existing MCC's (including FVNRs, "tri-paks," and limiters) with Eaton S811 Soft Starters and new wrappers manufactured by Eaton's Mississauga, Ontario, satellite plant; and Saved time and money, avoided full replacement; gained Modbus TCP/IP communications. The small size of Eaton's S811 device was said to be a key factor to the success of the retrofit. An integrated "run bypass" contactor also reduced space needed for the retrofit; the D77D-EMA enabled the customer to obtain critical motor data from the S811 (communication capability). Noteworthy was the unusual challenge of trying to retrofit a competitor's MCC with a SSRV in a "wrapper" sized for a NEMA starter, according to those involved. —Edited by Mark T.

There are some applications in which the standard tuning procedure using the PID filter of the controller cannot completely eliminate the resonance in a system. Resonance occurs when the natural frequency of a system is excited in a way that increases the amplitude of oscillation. This is usually due to system compliance, such as a mechanical coupling or inherent motor characteristics.
Since motion control systems are designed to force the motor to follow the commanded position, any deviation between the commanded and actual positions is considered a position error. With that in mind, designers should focus their efforts on reducing the position error.
