Features:
- Divides general drive, motor-loop, and calculation-intensive tasks among DCP, MCP, and CMP sections.
- Exchanges data among the three processor sections through dual-ported RAM.
- Presents documented normal and fault patterns through ten onboard diagnostic LEDs.
The
DS200SDCCG1A is the fully featured G1 SDCC group identified for AC2000, DC2000, and EX2000 equipment. Group designation matters because other SDCC groups do not carry the same application scope.
Multiple plug connectors distribute power, serial communication, LAN, motor-control, and auxiliary-board signals. The layout also accepts documented option cards on the SDCC assembly through dedicated connectors and standoffs.
Processor resets can originate from control power, watchdog, local, or system paths. Reading the LED pattern together with testpoint and connector behavior helps separate a processor-section fault from an external interface problem.
Official General Electric documentation and a quotation for the DS200SDCCG1A Drive Control Card are available through Apter Power.

SDCC LED and Reset Diagnostics
- LED array: Ten onboard indicators present documented processor and board fault patterns.
- Pattern reading: The complete LED combination distinguishes normal states from isolated processor faults.
- Testpoints: Board testpoints expose selected processor and interface signals for comparison.
- Reset sources: Supply, watchdog, local, and system reset paths can produce different restart behavior.
- Interface isolation: Connector-specific symptoms can be compared with processor indications before attributing a full-card fault.
Three-Processor Control Architecture
- Drive Control Processor: The 80C186-based DCP handles general drive control and peripheral interaction.
- Motor Control Processor: The MCP performs rapid arithmetic and I/O work for motor-control loops.
- Co-motor Processor: The CMP supplies calculation-intensive support for coordinated control functions.
- Shared memory: Dual-ported RAM transfers data among the three processing sections.
- Functional division: Independent task allocation allows a fault to affect one processor path without identical symptoms across the card.
G1 Hardware and Software Configuration
- Group identity: G1 is the SDCC group documented for AC2000, DC2000, and EX2000.
- Hardware jumpers: JP and WJ devices define configurable board options and circuit routing.
- Software sockets: A DS200 board may be supplied without the software-memory devices included with a DS215 assembly.
- Option boards: Dedicated connectors and standoffs accept the documented auxiliary cards.
- Connector map: Power, LAN, serial, motor-control, and auxiliary signals use assigned plug locations.
AC2000, DC2000, and EX2000 Uses
- AC drive control: The G1 SDCC architecture supports AC2000 control functions.
- DC drive control: DC2000 applications use the card as the main drive-processing assembly.
- Exciter control: EX2000 applies the same three-processor division to exciter functions.
- Motor-loop execution: MCP processing serves time-sensitive motor I/O and loop calculations.
- Coordinated calculation: CMP resources handle conditional work that supplements the DCP control sequence.
