摘要：
A method according to the invention of controlling a rotation speed of a motor of a speed-controllable hoist drive comprises receiving a lift speed instruction (ώ'm )\ forming a final speed instruction (ώm ) by using initial information con- taining the lift speed instruction (ώ'm ); and using the final speed instruction (ώm ) as a speed instruction for the rotation speed of the motor of the speed- controllable hoist drive. The method further comprises monitoring a position derivative of an actual value of a cable force (dF/dz). The initial information for forming the final speed instruction (ώm ) comprises the position derivative of the actual value of the cable force (dF/dz).
