ABSTRACT:
A conveyance (10) is provided with automatic limiting (223) of the rate of change in power supplied to first (26a or 232a) and second (26b) motors, whether the motors are electrical or hydraulic; and dynamic braking of electric motors (26a and 26b) is achieved by shorting a motor winding (150a) during a portion (233a) of an interval (217a) between power pulses (207a) of a pulse-width-modulated driving voltage (209a).
