In a method and device for controlling a hydraulic drive system, in particular in a crane or construction machine, a closed hydraulic circuit has a hydraulic pump and motor in which depending upon a desired value (n<SUB>des</SUB>) of an output parameter of the hydraulic circuit, an actuating signal (I) is generated for adjusting the hydraulic pump and/or motor. The actuating signal (I) is limited and/or reduced by a superordinate control module ( 6 ) depending on matching of a specified power value (P<SUB>+</SUB>; P<SUB>-</SUB>) with a current power value (P<SUB>Pu</SUB>; P<SUB>M</SUB>) of the hydraulic pump and/or motor.
