  • Page 3: General

    • 3 GENERAL Vacon NX frequency converters can be connected to the Profibus DP using a fieldbus board. The con- verter can then be controlled, monitored and programmed from the Host system. The Profibus fieldbus board shall be installed in slot E on the control board of the frequency con- verter.
