Abstract
A frequency converter control unit has: a serial control unit interface, a control unit clock pulse generator for generating a control unit clock pulse, and a control unit processor which is designed to define a control parameter depending on an actual value. A power unit has a data connection to the control unit and has several power semiconductors, a power unit clock pulse generator for generating an adjustable power unit clock pulse, a serial power unit interface, a clock pulse generator adjustment unit which has a signal connection to the power unit interface and which adjusts the power unit clock pulse depending on signals received by the power unit on the power unit interface, a power unit processor which controls the power semiconductors depending on the control parameter and the power unit clock pulse, and a sensor unit that determines the actual value. The control unit transmits the control parameter via the control unit interface to the power unit. The power unit transmits the actual value via the power unit interface to the control unit.
