Abstract: The invention relates to a method for protecting against over voltage that is simple to produce, economical, compact and is simultaneously effective against over voltage for a converter (8) provided for supplying an electric motor (1) comprising at least one motor phase (L1, L2, L3). Said converter comprises an electric intermediate circuit (10) and several half-bridges (13a, 13b, 13c) that are connected in parallel in the intermediate circuit and respectively comprise a circuit breaker (15a, 15b, 15c) on the high potential side and a circuit breaker (17a, 17b, 17c) on the low potential side, in addition to an intermediately connected phase connection (14a, 14b, 14c).

Abstract: An actuator (10) includes sensors (12) which are used to detect variables representing the operating state of the actuator (10) and are connected to an evaluation unit (16) associated with the actuator (10). The evaluation unit (16) is connected to sensors (12) and/or control actuating elements (13) by means of a first data bus (15). The sensors (12) are used to detect measurable variables representing the operating state of the actuator (10), and to transmit the same to the evaluation unit (16).

Abstract: The invention relates to a method for adapting the parameters (32) of a control and/or regulating device (1,4). The control and/or regulating device (1,4) is provided in particular for a machine tool or production machine. A parameter (32) has one or several attributes (34), wherein the attributes (18,34) of several parameters (32) are determined by means of at least one set of data (14,16,17) for attribute description. The invention also relates to a control and/or regulating device for carrying out said method.

Abstract: The invention relates to an open drive regulator and a method for software generation which offers the capability for customer-specific selection of function objects which are compiled separately. The compiled function objects can be preprocessed in the form of a library routines. Based on the instantiated and compiled function objects, the software for the drive regulator is generated or is loaded online for an existing program sequence. It is particularly advantageous that the function objects can be changed by a customer, for example in order to implement a customer-specific functionality.

Abstract: By distributing the intelligence of a drive between a control unit and one or more intelligent power sections by using a high-power standardized serial interface for connecting these components, it is possible as a result to identify different power components with their performance data, and also to diagnose them. Furthermore, independent innovations of the components are possible without having corresponding effects on the other components.
