The invention discloses a frequency conversion control method for an elevator. The method comprises the steps that the elevator is started, frequency conversion acceleration of the elevator is performed, the working frequency of the elevator is increased to ascending frequency, and an elevator bucket moves upwards at the ascending frequency; before the elevator bucket moves upwards to a track changing position, frequency conversion deceleration of the elevator is performed, the working frequency of the elevator is decreased to track changing frequency, and the elevator bucket performs constant speed track changing at the track changing frequency; the elevator bucket moves to an upper unoperated position after track changing is performed, and the elevator stops. According to the frequency conversion control method for the elevator, before the elevator bucket moves upwards to the track changing position, the working frequency of the elevator is decreased to enable the elevator bucket to be decelerated and perform constant speed track changing, on the premise that the running time of the elevator bucket is guaranteed, the stability of an elevator bucket track changing motion is improved, the torsion of the elevator in the process of track changing and turnover is decreased, and a motor is protected; meanwhile, the bucket falling or bucket slipping phenomenon can be avoided, the operational performance of the elevator is effectively improved, and the potential safety hazards of the elevator in the process of using are eliminated.
