Abstract:
A method for controlling the motor of a tool magazine (120) that rotates around a horizontal rotation axis (120a) is configured so that: at least two indexing positions for the tool magazine (120) are determined; the load torque acting on the tool magazine (120) when stopped at said indexing positions is measured; an unbalance torque, which is the load torque when stopped at the indexing position at which the load torque when stopped is maximal, is calculated from multiple load torques when stopped; and the servo motor (18) for the tool magazine (120) is controlled on the basis of the unbalance torque.
