Abstract: Disclosed herein is a method for predicting a faulty behaviour of an electrical converter.

Abstract: An arrangement for monitoring an antifriction bearing of a rotating shaft of a rotating electric machine. The arrangement includes: one or more capacitor electrodes to measure a capacitive shaft displacement parameter; one or more of the following additional measurement sensors; a microphone to measure a bearing noise parameter, a voltage sensor to measure a bearing current parameter, and/or an optical pyrometer to measure a shaft heat parameter; and one or more processors configured to evaluate a condition of the antifriction bearing based on the capacitive shaft displacement parameter and one or more of the following: the bearing noise parameter, the bearing current parameter, and/or the shaft heat parameter.

Abstract: To provide adaptiveness to data collected on an industrial automation device, a test is used for a specific need. A set of parameter values to be used during the test are temporary and send to the industrial automation device with an indication of a test. Before the test is run, existing parameter values are backed up, and they are restored after the test.

Abstract: Automated power conversion device operation and status data is received in a local terminal device. The operation and status data is forwarded from the local device to a remote device via a communications network. The remote device receives the operation and status data, and compares the received automated power conversion device operation and status data with automated power conversion device history data stored in a memory. Based on the comparing, the remote device generates a service recommendation for the automated power conversion device, Based on the generating, the remote device transmits the service recommendation to the local device via the communications network. The service recommendation is received in the local device. The local device displays the received service recommendation in to the user of the local device.

Abstract: A method comprises storing, in an automated power conversion device, operational information on the usage of the automated power conversion device, and information on user-adjustable parameter settings of the automated power conversion device. A local terminal device receives the operational information and the information on the user-adjustable parameter settings from the automated power conversion device, and forwards said information to a remote network node via a communications network. The received information is analyzed in the remote network node, and based on the analysis the remote network node generates a recommendation on an optimal set of user-adjustable parameters regarding the automated power conversion device. The generated recommendation is transmitted from the remote network node and received in the local terminal device.

Abstract: Automated power conversion device operation and status data is received (205) in a local terminal device (105). The operation and status data is forwarded (206) from the local device (105) to a remote device (109) via a communications network. The remote device (109) receives (207) the operation and status data, and compares (207) the received automated power conversion device operation and status data with automated power conversion device history data stored in a memory. Based on the comparing, the remote device generates (207) a service recommendation for the automated power conversion device (101). Based on the generating, the remote device (109) transmits (208) the service recommendation to the local device (105) via the communications network. The service recommendation is received (209) in the local device (105). The local device (105) displays (209) the received service recommendation in to the user of the local device (105).

Abstract: A method and apparatus for testing the function of a Safe Torque Off (STO) feature for an electric drive. After activation of the STO feature, predefined switching commands are transmitted to power switches of the electric drive. Then a switching state of the power switches is determined responsive to the predefined switching commands. Finally, the functionality of the STO feature is determined based at least upon the determined switching states.
