A method for operating an electromagnetic lift that includes a generator-driven electromagnet comprises adjusting a position of the electromagnet, in response to a first position command. Upon receiving a lift command, an output power level of a generator is established at a predetermined level above a predefined normal power level. In response to an excess release command, the output power level is set to a first predetermined level below the normal power level. In response to a transport command, the output power level is established as approximately the normal power level. Upon receiving a release command, the output power level is established at a second predetermined level below the normal power level.
