DS200PCCAG1ABB combustion engine card

The DC drive named DCS 500B is equipped with a SDCS-CON-2 microprocessor board. The original version was called DCS 500 and was equipped with a SDCS-CON-1 board. The DCS 500B has a MODBUS communication bus connection, which is a common bus protocol for ABB Drives products for the panel link. The DCS 500B drive can be controlled by means of digital and analog inputs or via the CDP 312 Control Panel. The DCS 500B software contains the function blocks of a standard application program and function blocks which can be connected to each other to form more advanced application programs. A standard program is designed so that it contains numerous functions, is flexible and suitable for most of the basic drive applications. Typical application areas for DCS 500B are: • Winder control • Master Follower • Positioning Control • Ski Lifts • Battery Charging • Cranes

Software Overview Parameter Sets

 Two parameter sets are available for two different applications in a drive. Example: A digital input can be used to select 1 of 2 parameter sets. Parameter set 1 is for motor set 1 and parameter set 2 is for motor set 2. A digital output is used to control external hardware which selects the actual motor 1 or motor 2 connection.The converter program is stored in a FPROM memory circuit (D33).The parameters for the converter and the field exciter are stored in one FPROM memory circuit (D35). The circuits are installed on the control board SCDS-CON-2.

If a field exciter module SDCS-FEX-2 or DCF 503/4 (SDCSFEX-3x) is used the version of the field exciter software can be identified in two ways: - software version is printed on a label on the micro controller of the field supply unit SDCS-FEX-2 or DCF 503/4 - the signal FEXC1 SW VERSION (11220) indicates the converter program version. when two field exciter units are installed in the drive, the program version of the second unit can be read from signal FEXC2 SW VERSION (11221). All the parameters of two-phase field exciter units are stored in the FPROM memory circuit (D35) of the converter.

Function Blocks

 DCS 500B control program is made completely by function blocks. The program can be modified with the control panel CDP312 or a PC-based tool program CMT/DCS500B. Every function block, used in the control program, has a structure similar to the one shown in figure 4. Additional function blocks exist in every converter. They can be used in the same way as the ones, shown in this document. For more information, please see the APPLICATION BLOCKS manual. If additional function blocks are used, the converter should be labeled with a sticker indicating the type of application by any code or plain text.
