Abstract: The invention relates to the programming of a motor controller by means of a configuration file which is sent to the motor controller. The configuration file is typically sent from a PC, but with this invention it is now possible to generate and to download the file directly to the motor controller from an Internet server. The Internet server is provided by the manufacturer of the motor controller and contains an interactive programming software, a motor controller database, a compiler and a transmitter unit. The invention makes up-dating and maintenance of the motor controller software quicker and easier as known so far.

Abstract: The invention is directed to controlling an electric motor by means of a frequency converter. The frequency converter can be connected to one of several different mains voltages. According to the present invention, the maximum output power of the frequency converter, is limited when the actual mains voltage is lower than the maximum nominal mains voltage, for which the frequency converter is designed, and during the limitation the frequency converter controls the speed of the motor within a power range up to a limited maximum output power. This gives a genuine multi-voltage unit, which can be connected to a wide range of mains voltages.
