  • Page 6: Specified Application

    The used semiconductors and components of the Karl E.Brinkmann GmbH are developed and dimensioned for the use in industrial products. If the KEB COMBIVERT G6 is used in machines, which work under exceptional conditions or if essential functions, life-supporting measures or an extraordinary safety step must be fulfilled, the necessary reliability and secu- rity must be ensured by the machine builder.

  • Page 7: Parameter Description

    Parameter Description Parameter Description On delivery the KEB COMBIVERT G6 is assigned with an user menu, the customer parame- ters (CP-Parameters). These represent a selection of important parameters for the operation. Up to a maximum of 48 customer parameters can be defined from over 500 parameters.
