Abstract

See full text

A system for controlling operation of a winch assembly having an electric motor, a drum, and a cable. A controller is configured to access a winch load threshold, with the winch load threshold defining a hold zone and a reel zone, and one of the hold zone and the reel zone including loads greater than the winch load threshold and another of the hold zone and the reel zone including loads less than the winch load threshold. The controller is further configured to determine whether the drum is rotating, determine whether the winch assembly is operating within the hold zone or the reel zone, generate a hold current while the winch assembly is operating within the hold zone preventing rotation of the electric motor, and generate a reel current while the drum is operating within the reel zone permitting rotation of the electric motor.
