    • In a method for monitoring a stationary condition of a drive device, a monitoring device provides the drive device with a temporally varying monitoring signal which, when a sensor device connected to the drive device functions properly, modulates a sensor output signal of the sensor device in accordance with the monitoring input signal. The monitoring device receives the sensor signal and monitors it for the presence of a corresponding signal component. In the absence of such a signal component, the monitoring device controls a safety device which converts the drive device into a safe state. When the drive device is controlled by means of at least two phase-shifted current regulators, it is possible for the monitoring device to monitor an output signal of at least one of the current regulators for constancy and to control the safety device when the output signal of the at least one current regulator changes.

    • A method for safely limiting the torque of a frequency-converter-fed three-phase motor operated under field-oriented control (controlled torque) is disclosed. Actual phase current values of the three-phase motor are used to calculate a sum current signal on two channels which is checked for a sum current value of zero. A rotor position angle is determined on the two channels, and torque-forming current components of the two orthogonal field-oriented current components of a stator current space vector are calculated on the two channels as a function of the measured phase currents and the rotor position angle. The three-phase motor is switched on the two channels without applying a torque if the sum value is not equal to zero and/or if the torque-forming current components calculated on the two channels are not equal. This produces a safety function “safe torque limiting” which can be integrated in commercially available frequency converters.
    • 公开了一种用于安全地限制在场定向控制(受控转矩)下操作的变频器供电的三相电动机的转矩的方法。 使用三相电机的实际相电流值来计算两个通道上的和电流信号,该信号检查和电流值为零。 在两个通道上确定转子位置角,并且在两个通道上计算定子电流空间矢量的两个正交磁场定向电流分量的转矩形成电流分量作为测量的相电流和转子位置的函数 角度。 如果和值不等于零,并且/或如果在两个通道上计算的转矩形成电流分量不相等,则三相电动机在两个通道上接通而不施加转矩。 这产生了可以集成在市售变频器中的安全功能“安全转矩限制”。

    • A machine having two machine parts, of which one is able to be rotated relative to the other, in which light signals are transferred from the one part to the other part. The light signals are transmitted radially to the axis of rotation of the rotatable machine part. In a first embodiment a plurality of light sources couple light into an optical waveguide ring which is coupled out over the entire outer circle of the optical waveguide ring so that it is guaranteed that light signals reach a receiver arranged radially outside in each case. In another embodiment light sources couple light into optical waveguide structures, with branches of the optical waveguides guaranteeing that on the outer circle of the one component the exit points for light are sufficiently dense that for any given angular position of the rotatable component at least one of two receivers receives a light signal.

    • There is described a method for monitoring a drive device for a defective sensor signal from a first sensor of the drive device and to a monitoring device which is suitable for this purpose. Although sensors operate reliably, sensor errors which may give rise to significant damage if they are not detected may arise. Monitoring the sensor makes it possible to increase the reliability of the drive device. The sensor signal from the first sensor is compared with a sensor signal from a second sensor in such a manner that the first sensor is monitored. In this case, the monitoring device is intended, in particular, for a sensor having a sensor disc.

    • A drive controller for a self-commutated converter having two half-bridges with converter valves, includes two control circuits, with each control circuit associated with a corresponding half-bridge and operatively connected with the converter valves of that half-bridge, and at least two switches, wherein an input of each switch is directly or indirectly connected to an external voltage, and an output of each switch is directly or indirectly connected to a pulse-inhibiting path. Further provided are at least two pulse-inhibiting controllers, wherein each switch receives control signals from a corresponding one of the pulse-inhibiting controllers. Arranged in the pulse-inhibiting path is a buffer unit for briefly maintaining a supply voltage of the control circuits if a pulse-inhibiting path electrically disconnects at least one of the control circuits from the external voltage. Thus, the drive controller, and more particularly its pulse-inhibiting paths, can be tested cyclically without interrupting the operation of the drive controller.
