A winch controller for a hoisting apparatus for a wireline operation operates as a closed loop controller. The winch controller is adapted to control a winch or, if included, a winch and a capstan in a coordinated manner. The winch controller may utilize process variables including the tension of the cable between the winch and the capstan. The controller is coupled to a power pack adapted to power the winch and capstan. The power pack and controller are configured such that the capstan may be selectively removed from the system when it is not needed.
