FIELD: electric equipment for mining machines, possible use in low-voltage set devices of quarry excavators.
SUBSTANCE: method includes generating command signals for force, lifting and turning or driving motors by means of two command devices, measuring voltages and currents of anchor windings of motors and generating control signals for power amplifiers of appropriate motors in function of command signals and measured values of currents and voltages of appropriate motors by means of microcontroller adjusting devices. Memory of each microcontroller adjusting device stores identification numbers of all main movement drives, appropriate for their values, and command signals for drives are generated in form of serial codes, containing information about identification number of drive and value of setting effect.
EFFECT: increased quality of processes for controlling drives of excavator main movement in different modes of operation.
