<p>An arrangement for controlling two drive units which interact with one another, one of which includes a hydraulically driven motor ( 2 ). The motor drives a varying load, and one or more valves ( 6, 7 ) control hydraulic fluid flow through the motor during operation and for starting and stopping of the motor. One of the valves is a flow control valve ( 7 ) for flow control of the hydraulic fluid flow through the motor. The second drive unit ( 37 ) performs a working movement which, under the action of hydraulic flow influences the loading of the motor. The flow of the hydraulic fluid to the second drive unit is controlled in a coordinated way with the control of the flow through the motor.</p> |
