Features:
- Applies TC2000-specific firmware and an enlarged field-adjustable parameter area.
- Splits drive logic, motor control, and intensive calculations across three processors.
- Reports normal and fault states through a ten-position diagnostic LED bank.
The General Electric
DS200SDCCG4A is the G4 SDCC group intended for TC2000 turbine control. Its group identity is significant because G1 serves different drive families and G3 has reduced functionality.
Power, LAN, terminal-board, signal-processing, and meter paths reach the card through eight identified connector positions. Matching every plug destination and companion board prevents a mechanically similar SDCC from being treated as an electrical substitute.
Configuration work combines EEPROM-size jumper checks with observation of the complete LED pattern and active reset source. These checks distinguish parameter access errors from external interface faults before the controller is returned to service.

Three Processor Workloads
- Card role: The DS200SDCCG4A distributes TC2000 control tasks across three 16-bit devices.
- Drive Control Processor: An 80C186 manages user interfaces, outer regulating loops, and system-level functions.
- Motor Control Processor: An 80C196 handles high-speed I/O, timers, current regulation, and motor-specific loops.
- Co-motor Processor: A TMS320C25 supplies extra capacity for math-intensive control algorithms.
- Shared data path: Dual-ported RAM exchanges operating data among the processor sections.
Eight SDCC Signal Paths
- Power interfaces: The DS200SDCCG4A uses 1PL and 2PL for power-supply board signals and dc inputs.
- LAN output: Connector 3PL carries SDCC outputs toward the LAN communications card.
- Terminal-board I/O: Connectors 6PL and 8PL exchange customer and drive-terminal signals.
- Signal processor: Connector 7PL links the SDCC with an SPC or SPCB board.
- Meter output: Connector 11PL provides the designated output path to meters.
- Unused position: Connector 9PL is identified as not used.
Fault Codes and Reset Sources
- LED bank: The DS200SDCCG4A presents operating and fault states through ten onboard indicators.
- BCD range: Fault numbers below 399 use the documented three-digit BCD pattern.
- Binary range: Higher fault numbers are represented across the LED bank in binary form.
- Normal sequence: A moving two-light pattern indicates the no-fault or not-running state.
- Reset paths: Supply, watchdog, local, customer-interface, and programmed resets can restart the card.
G4 Setup Controls
- TC2000 identity: The DS200SDCCG4A combines the G4 firmware application with enlarged field-adjustable parameter storage.
- EEPROM jumpers: WJ7 through WJ10 must agree with the installed memory-size arrangement.
- Parameter access: Incorrect EEPROM-size settings can cause parameters to be read or configured incorrectly.
- Rack matching: Group, software devices, plug destinations, and companion boards must match the installed controller.
- Safe handling: Control power must be removed and stored energy discharged before the card or its connectors are disturbed.
