    Ferrite rings are required to minimize electrical disturbances on the DC bus connections between the inverter(s) and the COMBIVERT R6 unit. The ferrite rings are to be installed over both the ++ and -- DC bus conductors. Do not use ferrite rings intended for the inverter(s)' motor leads on the DC bus as doing so negates the effect. Do not pass ground conductors through the ferrite rings.

    To prevent malfunctions, the COMBIVERT must be brought into nOP status before connecting or disconnecting the operator (de-activate the enable input). When starting the COMBIVERT R6, it is started with the last stored values or factory settings regardless of whether the operator is installed or not.

    CP.02. CP.02 displays the actual regenerative frequency, if the COMBIVERT R6-N is in "netof" state, i.e. the main line is off. The rotating fi eld of the mains frequency is displayed as follows: (+) right, (-) left This value should be positive.
  • Page 32 CP.12 Over load counter The average load of the COMBIVERT R6-N can be evaluated with this parameter in order to avoid an Error Overload (time based overload). When the actual load goes above 105%, the counter begins to increment. The Error Overload is triggered, if the overload counter reaches 100 %.
  • Page 33 This parameter displays the identifi cation code of the power part. When the unit is fi rst turned on, the COMBIVERT R6 determines which line voltage it is connected to (230V/480V). Depending on that, various internal parameters are set. If the unit is then connected to another line voltage, the internal parameter settings are not correct.
