Abstract: To detect amplitude deviations and/or offset deviations in two sinusoidal signals (S1, S2), electrically staggered from each other by 90.degree., both signals (S1, S2) are evaluated by way of threshold stages (K11, K12, K21, K22). The zero passages of the one signal (S1, S2) each indicate trigger time points (1.sub.up, 1.sub.down, 2.sub.up, 2.sub.down) for the amplitude of the other signal (S2, S1) in each instance. The output signals (X1, X2, A, A, B, B) of the threshold stages (K11, K12, K21, K22) are analyzed in the a regulating mechanism. Regulation can take place in accordance with the errors detected.

Abstract: A drive unit for a machine, in particular a machine-tool, robot and the like, is described. The drive unit has several components, and each component has at least one associated component-specific function, and a uniform communication module that forms an interface with the other components. The interfaces of the various components can be connected by logical point-to-point connections or via a bus. Each component is designated with a particular type, and the communication between the components uses a type-specific communication protocol. A least one of the components is a hierarchically superior component.

Abstract: An inverter includes a mains system side freewheeling pulse converter and a load-side freewheeling pulse converter, which are electrically connected on the DC side via a DC intermediate circuit. The mains system side and load-side freewheeling pulse converters each include switchable current valves in form of semiconductor switches that are made of silicon carbide with a high blocking voltage. The inverter can operate at higher voltages and frequencies, without affecting the load rating.

Abstract: A method and apparatus for generating a voltage (u.sub.DK) proportional to the rotational-speed uses a resolver (2), which outputs two path-dependent or angle-dependent, amplitude-modulated (AM) sinusoidal voltages (S.sub.1, S.sub.2) in phase quadrature. The sinusoidal voltages have amplitudes that can be modulated depending upon the rotor position or the angle of rotation (.alpha.), and can be tapped. According to the invention, a sinusoidal amplitude signal (R.sub.L1, R.sub.L2) dependent on the rotor position or the angle of rotation (.alpha.) is extracted from the two AM sinusoidal voltages (S.sub.1, S.sub.2). These sinusoidal amplitude signals (R.sub.1, R.sub.L2) are converted into an approximated, sinusoidal signal (R.sub.L1A, R.sub.L2A), which is linear around the zero crossing in a range of.+-.45.degree.. Each approximated, sinusoidal signal (R.sub.L1A, R.sub.L2A) is differentiated and subsequently inverted; and an analog rotational-speed-proportional voltage (u.sub.DK) is formed which depends upon a detected rotor position (.alpha.) from the two differentiated signals (R'.sub.L1A, R'.sub.L2A) and from the two inverted differentiated signals (R'.sub.L1A , R'.sub.L2A). This method and apparatus obtains a cost-effective method for detecting low rotational-speeds, which are measured by means of a resolver (2).

Abstract: A linear, path or angle dependent signal sequence (E) is formed from two path or angle dependent signals (A, B) of equal amplitude and period having an electrical phase offset to each other of 90.degree. and being generated by an incremental transmitter (GS), in that the transmitter signals (A,B) are rectified and an output signal is formed in a converter (U1), which [output signal] corresponds to the quotient of the respectively smaller absolute value (.vertline.A.vertline. or .vertline.B.vertline.) of the signals (A or B) to the sum (.vertline.A.vertline.+.vertline.B.vertline.) of the absolute values (.vertline.A.vertline., .vertline.B.vertline.) of both signals (A, B). The respective, precise position is detected from this signal sequence by means of a digital convervison.

Abstract: For the safe evaluation of sensor signals, singular further processing is permitted by producing a redundancy signal in accordance with a prescribed algorithm when the sensor signals are actually generated. The redundant single-channel nature is made possible by virtue of safety-conforming data processing and data transmission being carried out on a single channel by virtue of a downstream processing device deriving dual-channel signals therefrom, by reversing the algorithm, and testing them for plausibility by reciprocal result comparison.
