    Block diagram The signals and parameter settings depicted in the diagram are re- quired for a speed-controlled 12-pulse drive with DCS 500 in a Master-Slave configuration. The function block shown is included in the basic software, and is activated when required using Parameter 1209.

  • Page 12: Switch-On/Switch-Off Logic

    Both units work more or less independently, controlling their own line contactors and the enables. Switch-on/switch-off For the DCS 500 in its 12-pulse mode, an additional logic is pro- logic vided, which in the event of an error will disable both units through the INHIBIT input of the drive logic.

    For instructions on start-up, please consult the Installation and Start-up Manual (DCS 500). It is best to disconnect the non-active unit from the mains, or at least to disable it by suppressing the firing pulses. The interphase reactor can remain connected throughout the entire start-up procedure.
