Abstract

Method of accumulating energy created by the brake resistor, based on the recovery device, connected to the power part of the frequency converter, detecting the excess electric energy, created in the generator mode of the drive, and converting this recovered energy to the power supply level of the control electronics unit and subsequently accumulating it to supply power to the control electronics when this excess energy is not available. Circuitry for implementing the method which has the mains voltage distribution (1) connected through a cable (8) to the drive control source circuit (2), from which it is connected through the mains supply line (9) to the control electronics source circuit (3) as well as connected through cable (11) to the converter power part (5), wherein the source circuits (3) are connected through cable (10) to the control electronics unit (4), while the drive power part (5) is connected to the drive (6) as well as connected through cable (13) to the recovery unit (7R), which is then further connected through cable (14) to the control electronics source circuit (3).
