Duringinitial power-up, the frequency converterautomatically sets this parameter to [3] OptionA if it detects a valid fieldbus option installedin slot A. If the option is removed, thefrequency converter detects a change in theconfiguration, sets parameter 8-02 ControlSource to default setting [1] FC Port, and thefrequency converter then trips. If an option isinstalled after initial power-up, the setting ofparameter 8-02 Control Source does notchange, but the frequency converter trips andshows alarm 67, Option Changed.[0] None[1] FC RS485[2] FC USB[3] * Option A[4] Option B[5] Option C0[6] Option C1[30] External Can8-03 Control Timeout TimeRange: Function:Sizerelated*[1 -18000 s]Enter the maximum time expected to passbetween the reception of 2 consecutivetelegrams.
