An access control apparatus and method for controlling a configuration of an automation apparatus. The method includes: reading authentication information from an electronic tag; transmitting the authentication information to a networked service; receiving access rights from the networked service; and controlling the configuration of the automation apparatus according to the access rights.

Access control apparatus and method for controlling configuration of automation apparatus

An automation apparatus, a reader apparatus, and a method for configuring an automation apparatus. The method includes: harvesting wirelessly, by a passive electronic tag, energy from a reader apparatus; receiving wirelessly, by the passive electronic tag, configuration data from the reader apparatus; storing, by the passive electronic tag, the configuration data to a non-volatile memory of the passive electronic tag; and reading, by a processor, the configuration data from the passive electronic tag.

Method for configuring automation apparatus, automation apparatus, and reader apparatus

An electrical drive system including an inverter and an electrical machine supplied by the inverter. A method for controlling the electrical drive system includes: receiving a machine current signal and a machine voltage signal of a machine current supplied to the electrical machine; determining a switching signal based on the machine current signal and controlling the inverter with the switching signal; estimating a first speed estimate from the machine current signal; estimating a second speed estimate from the machine voltage signal; and comparing the first speed estimate and the second speed estimate with each other, and, when the first speed estimate and the second speed estimate deviate from each other more than a threshold, activating a fault reaction of the electrical drive system, which sets the electrical drive system to a predefined state.
