20150214873 | METHOD FOR DIAGNOSING A FREQUENCY CONVERTER - A method for diagnosing a frequency converter is used for a frequency converter having a positive and negative DC link voltage which is applied via bridges of switching elements in an alternating sequence to phases of a motor. Pulse width modulation (PWM) signals drive the switching elements for a respective one of the phases and current sensors capture phase currents. In a step a), PWM signals are applied as test patterns to the switching elements. In a step b), sensor signals of the current current sensors are picked up. In a step c), the sensor signals are evaluated by ascertaining a presence of the DC link voltage upon a displacement current being recognized in the sensor signals. | 07-30-2015 |

20090055561 | Bus Module for Connection to a Bus System and Use of Such a Bus Module in an AS-I Bus System - Disclosed is a bus module that can be connected to a bus system and comprises means for outputting safety-relevant signals in the form of repeated unambiguous code sequences. The bus module further comprises a first and second arithmetic unit with means for executing software programs. A code generator program of the first arithmetic unit generates a first partial code sequence of the code sequence while a code generator program of the second arithmetic unit generates the remaining portion of the code sequence as a second partial code sequence. Advantageously, a proper code sequence is output at the output of the bus module only when both arithmetic units function properly. A deviation in the code sequence that is output can then be detected by a monitor or actuator. | 02-26-2009 |

20120182095 | INSTALLATION SWITCHING DEVICE - An installation switching device which rapidly disconnects short-circuit currents is provided. A contact lever is arranged at least partially in an air gap in a magnetic circuit such that, in case of a short circuit, the interaction between current flow and magnetic flux within the air gap can result in an electrodynamic force effect, which leads to rapid opening of at least one contact point. A switching mechanism acts via a first operating connecting line on the contact lever to open the contact point and/or to keep it open. In case of overcurrent tripping, an overcurrent release acts, by a switching mechanism and via a second operating connecting line, on the switching mechanism to open the contact point and keep it open. In case of short-circuit tripping, the contact lever acts via a third operating connecting line on the switching mechanism to keep the contact point open. | 07-19-2012 |
20120182096 | INSTALLATION SWITCHING DEVICE - A current path in an installation switching device includes first and second contact points, which respectively include first and second levers. The second lever is arranged in an air gap in a magnetic circuit. In case of a short circuit, an electrodynamic force, which leads to rapid opening of the second contact point, can act on the second lever due to interaction of current flow with magnetic flux within the air gap. A switching mechanism acts via a first connecting line on the first lever to open and/or keep open the first contact point. In case of overcurrent tripping, an overcurrent release acts through the switching mechanism and a second connecting line on the switching mechanism to open and keep open the first contact point. In case of short-circuit tripping, the second lever acts via a third connecting line on the switching mechanism to keep the first contact point open. | 07-19-2012 |
