Abstract
To obtain an improved possibility of establishing the causes of failure in linear drive devices with an electric drive, operational data logging means shall be provided for logging data in connection with operational loads and/or an operating state of the electric drive, which occur over a certain period of time, wherein the operational data logging means can be connected to the power connection means for data logging. Means for storing data, which are based on a plurality of measurements of the same measured variable, which measurements are performed one after another, make it possible to log and evaluate data over a long period of time, preferably during the entire service life of the linear drive device. The measurements are carried out during the use of the linear drive device (14) during which it is in a loaded state.
