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.
