Claim 12:
13. A method of controlling run-time operation of a drive system of a power machine, the method comprising:
receiving, at a control device, one or more signals indicating one or more of a commanded travel speed for the power machine or an output torque associated with an infinitely variable displacement hydraulic pump and an infinitely variable displacement hydraulic drive motor of a hydraulic drive circuit of the power machine;
determining, using the control device, a control value for the hydraulic drive motor, based on the one or more signals; and
selectively operating the hydraulic drive motor within either of a first displacement range or a second displacement range that overlaps with but is different from the first displacement range, including: adjusting a run-time displacement for the hydraulic drive motor, using the control device, based on the control value and, respectively, the first or second displacement range, such that a maximum run-time displacement and a minimum run-time displacement are limited by the first or second displacement range, respectively.
