Abstract
A power machine having an engine that generates a torque output and a power conversion system configured to receive the torque output and provide a drive power signal in response to actuation signals for propelling the machine is disclosed. An engine controller provides an engine torque data signal indicative of a torque load on the engine. A user input device generates an input signal indicative of intention to propel the machine. An electronic controller is in communication with the user input device, the power conversion system, and the engine controller. The electronics controller receives the input signal and provides actuation signals to the power conversion system. The electronic controller further provides the actuation signals as a function of the engine torque data signal to limit the engine torque load.
