The basic version of the DCS550 is already equipped with a large number of standard hardware interfaces like an encoder, an analog tachogenerator and four analog input devices. Since the basic unit includes all important functions almost all applications are covered – options are not necessary. The single-volume documentation provides comprehensive information on the unit, firmware and hardware. The guided start-up and complementary support functions reduce startup times to a minimum. The grouped structure of the parameters provides easy and clearly arranged navigation within the various features and functions. Error messages and help texts are displayed in plaintext in the user’s native language. The reduced need for training is an additional advantage created by the synergies and similarities with ABB’s DCS800 converter and ABB AC-drives.
