Abstract: A method for controlling at least one servomotor in a braking manner with a frequency converter includes disconnecting a direct-voltage intermediate circuit from an electric alternating-voltage network, braking the servomotor by controlling semiconductor switches of an inverter circuit in a regenerative braking mode in order to reduce the speed of the servomotor, and controlling a brake chopper such that a brake resistor is switched on at a maximum intermediate-circuit voltage, which forms a switch-on threshold for the brake chopper, and is disconnected at a minimum intermediate-circuit voltage, which forms a switch-off threshold for the brake chopper. The switch-on threshold and/or the switch-off threshold are dynamically changed during regenerative braking of the servomotor as a function of the current speed of the servomotor.

Abstract: In a circuit and a method of clock interpolation, an input signal at a first frequency is processed and at least one output signal having a second frequency being a multiple of the first frequency of the input signal is output. The circuit is defined by the fact that the input signal is measured with respect to frequency and phase in a PLL frequency measuring circuit, and by the fact that the measured input signal is multiplied by at least one frequency multiplier and an oscillator that follows the frequency multiplier.

Abstract: In an industrial robot and a method for operating an industrial robot, a robot arm is pivotable with respect to multiple axes. At least one of the axes has an drive associated therewith for controlling movement of the robot arm with respect to that axis. The electrical drive includes a three-phase synchronous motor that is operated with associated electrical currents and electrical voltages. A signal representing at least one of said electrical currents and electrical voltages is supplied to a computerized control unit that determines, from the signal, the position of the axis associated with the electrical drive. The computerized control unit controls operation of the electrical drive dependent on this determined position.
