Abstract

The present invention relates to a method and a device for calibration of joint means in a rock-drilling rig comprising at least one joint means, wherein a joint motion speed for the said joint means is controllable by means of control means, and wherein the influence of the said control means upon the motional speed of the said joint means is designed to be controlled by a control parameter. The method comprises the steps of setting a value for a control parameter, determining whether the deviation between the joint motion speed obtained by means of the control parameter value and a reference joint motion speed falls below a certain threshold value, increasing/reducing the value for the said control parameter if the said deviation exceeds the said threshold value, and automatically repeating the above steps until the said deviation falls below the said threshold value. The invention also relates to a device and rock-drilling rig.
