FUNCTIONAL DESCRIPTION:

DS200SDCCG5A is a Digital Exciter Drive Control Card manufactured and designed by General Electric as part of the EX2000 Series used in the Excitation Control systems. The Drive Control Card (SDCC), which is the main processor board, contains the EX2000's primary control circuitry. It consists of three 16-bit microprocessors and associated circuits coupled via dual-ported RAM. It includes general-purpose interface circuitry that connects with other boards to form various types of excitation systems. This interface circuitry controls and processes exciter and customer I/O. It also expands processing capability via two external dual-ported RAMs. (In TC2000 applications, the interface circuitry and three primary microprocessors are utilized for various tasks.) The three primary processors of the SDCC are:

• An 80C186 microcontroller (U1) that employs both digital and analog I/O and has a variety of built-in peripheral features.

• Among these features are the direct memory access (DMA) controller, timer/counters, an interrupt controller, wait-state generators, and address decoding for chip choices. User interfaces, external regulating loops (such as speed and location), and system-level operations make up DCP software.

• A processor for motor control (MCP). a microcontroller (U21) with an 80C196 processor that has high-speed I/O, analog I/O, traditional digital I/O, timer/counters, and a watchdog timer. Inner loops like current regulators and motor/technology-specific features like dc phase control, ac motion control, and ac general purpose make up MCP software.

• For motor control algorithms that are too sophisticated for the MCP, a TMS320C25 digital signal processor (U35) executes math-intensive operations. Only when the drive requires the extra processing power does the SDCC use this processor and the electronics that go along with it? The only devices with which the CMP interfaces are its dual-ported RAM and EPROM.

• Five memory chips make up the onboard software for the DS200SDCC card: four EPROMs (U11, U12, U22, and U23) that carry factory-programmed configuration data and one EEPROM (U9) that stores field-adjustable settings. On the SDCC, these memory chips are housed in sockets.

AUXILIARY BOARD MOUNTING PROVISIONS:

Additional auxiliary boards and modules can be mounted using the SDCC mounting facilities. The SDCC is compatible with the following boards:

• DS215SLCC or 531X306LCC LAN Communications Card
• 531X309SPC Signal Processor Card
• DS200SPCB Multibridge Signal Processor Card

HARDWARE CONFIGURATION:

The SDCC includes configurable hardware that must be set correctly for the application:

• Berg-type (manually movable) hardware jumpers, identified by a JP nomenclature
• Wire jumpers, identified by a WJ nomenclature

These jumpers are utilized for user application options or factory testing. The majority of the jumper options are pre-set at the factory. These factory fixed positions are listed on the test data sheets that come with each controller (in the drive/exciter door pocket). The jumper descriptions are included in Table 2, starting with the default option.

SOFTWARE CONFIGURATION TOOLS:

The SDCC requires the use of the ST2000, GE Control System Toolbox, or LynxOS Drive Configurator for any software modification, download, or replacement. For any software modifications, the ST2000, GE Control System Toolbox, or LynxOS Drive Configurator instruction book, a suitable PC, and the relevant drive/exciter instruction book are also needed.
