Hardware Specifications

Processor Task Allocation & Control Platform Features

Operating as the primary computational engine for turbine drives, the SDCC architecture distributes complex math and signaling workloads across three specialized onboard processors.

• Processor Workload Division: The card splits processing tasks among its three microprocessors. One microprocessor dedicatedly processes active drive control loop algorithms. The other two manage motor-control processes, with one acting as a high-speed math co-processor for intensive real-time calculations.
• Dual-Port Shared RAM Integration: To prevent data latency and resource lockups, a high-speed shared RAM block allows all three microprocessors to access control variables simultaneously.
• Auxiliary Card Expansion: The board accepts multiple optional auxiliary expansion cards. This includes the Local Area Network (LAN) communications card, which supplies a dedicated serial port connector for remote computer linking and monitoring.

Frequently Asked Questions

Q: What is the primary function of the 2PL card connector on the DS200SDCCG1AHD?

A: The 2PL connector serves as the main DC power interface. It imports regulated +5 VDC, +/- 15 VDC, and +24 VDC power rails directly from the Power Supply / Interface Board to power the onboard logic and signal scaling circuitry.

Q: How is the drive control card configured or tuned during commissioning?

A: Configuration requires a serial connection from a local laptop to the serial port found on the optional LAN communications auxiliary card. Operators must utilize dedicated GE configuration software to download, edit, and upload the master drive configuration files.

Q: Can the same configuration file be uploaded to multiple SDCC boards?

A: Yes. If multiple drives across the system share identical operating parameters, the edited configuration file can be uploaded sequentially to each board to ensure software standardization and reduce commissioning time.

Field Installation Guidelines

• Electrical Hazard Isolation: Always isolate and lock out all high-energy power supplies to the drive panel before connecting or disconnecting the serial laptop cable. Touching components inside an energized drive enclosure can cause severe electrical shock or burns.
• Auxiliary Card Mounting: Ensure any optional boards (such as the LAN communications card) are firmly mated to the SDCC board headers and secured using the specified nylon standoffs before mounting the assembly into the drive cabinet.
• Laptop Serial Port Settings: Ensure the configuration laptop's COM port baud rate, parity, and stop bits are configured to match the communication requirements defined in the GE software instruction manual.
• ESD Mitigation Protocol: Keep the module within its static-shielding packaging until installation. Technicians must wear a grounded electrostatic discharge (ESD) wrist strap during handling to prevent latent gate damage to the microprocessors.
