Annotation: The paper considers the influence of output voltage harmonic components of a frequency converter on the coordinate precision of an oscillatory machine with double-way feed. The frequency converter circuit is based on self-switching valves and thyristor reverse in the power circuit. Certain recommendations for reduction of the maximum system instability coefficient due to the optimal choice of the control functions and load parameters are presented.

Keywords: frequency converter, oscillating motion drive, variable state method, coordinate accuracy, maximum instability coefficient
