发明名称 METHOD FOR AUTOMATICALLY ADJUSTING A NETWORK FREQUENCY PARAMETER OF A FREQUENCY CONVERTER CONNECTED TO THE NETWORK
摘要 The invention relates to a method for automatically recognizing a value of the parameter network frequency of a frequency converter connected to a network. According to the invention, the curve of a measured intermediate circuit voltage of the frequency converter is analyzed in order to verify if the network is a 50Hz or a 60Hz network, whereupon an analyzed value is entered as parameter network frequency . The frequency converter itself is capable of determining if it is connected to a 50Hz or 60Hz network, rendering unnecessary any intervention by a user.
