Technical Specifications
- Product Type: Servo Drive Control Board.
- System Compatibility: GE Speedtronic Mark V.
- Output Type: PWM or analog servo drive signals.
Functional Features
- Servo Positioning: Generates precise drive signals for hydraulic servo valves.
- Feedback Processing: Reads LVDT and potentiometer feedback to close the position control loop.
- Fault Detection: Monitors servo circuit health and detects open/short conditions.
Application Scenarios
- Fuel Control: Precise positioning of gas and liquid fuel valves.
- Steam Control: Governor valve positioning for speed and load regulation.
Performance Parameters
- Positioning Accuracy: High-resolution feedback processing for precise valve control.
- Response Time: Millisecond-level servo response for grid stability.
Material Composition
- PCB: High-reliability, multi-layer board with conformal coating.
- Components: Precision analog ICs and high-current driver transistors.
Structural Characteristics
- Form Factor: Standard Mark V board size.
- Connectors: High-density connectors for servo valve and feedback wiring.
Working Principle
Receives position commands from the Mark V regulator, compares them with actual LVDT feedback, and generates PWM or analog drive signals to move the servo valve to the exact commanded position, closing the control loop.
Installation Requirements
- Follow Mark V installation manuals for proper board placement.
- Ensure all servo valve and feedback cables are properly shielded and grounded.
- Configure servo parameters (gain, limits) in the control software.
Usage Precautions
- Never disconnect servo valve wiring while the turbine is in operation.
- Perform calibration and stroke testing after any board replacement.
- Strictly adhere to ESD protocols.
