The invention relates to a configurable diagnosis unit and to a system with an inverter and a configurable diagnosis unit, having the following - at least two signal inputs, each signal input containing at least one piece of state information as well as at least one piece of configuration information, - a diagnosis module which checks the state information of the signal inputs with respect to logical as well as temporal behavior and which has two or more independent function blocks, - a configuration module which evaluates the configuration information of the signal inputs and selects the function blocks of the diagnosis unit on the basis of the corresponding evaluation result, and - at least one output module which logically links the logical output state of the diagnosis module to the signal inputs and generates at least one output signal therefrom. A change in the state information in the input signal leads to a change in the logical output state of the output module, and a change in the configuration information in the input signal leads to an adapted change in the selection of the active function blocks.

The invention relates to a converter assembly, a method for producing a converter assembly and a method for operating a converter assembly, wherein a base module comprises the power electronics and the control electronics, said base module having a housing, in particular a housing that forms at least partially a housing part for the power and control electronics, said base module comprising an electrical and mechanical interface via which a signal electronics can be connected to the base module in a form- and/or force-fitting manner in order to form the converter assembly. According to the invention, the signal electronics comprises a housing so that, after connection, the housing of the signal electronics and the housing of the converter assembly together form a converter assembly housing, wherein a nominal value for rotational speed and/or torque can be electrically transmitted via the interface, the signal electronics comprising means for receiving, determining and/or inputting the nominal value.
