Functional Description

IS200WSVOH1A is a servo driver module developed by GE. It is a part of the Mark VIe control system. The servo driver assembly is designed to provide precise and reliable control of servo valves. It encompasses several key features and functionalities that contribute to its efficiency.

Power Supply Features

  • The servo driver assembly is equipped with a robust power supply system capable of converting a P28 voltage input into both +15 V and -15 V outputs. This dual voltage conversion is crucial for powering the current regulator circuits that drive the servo valves.
  • The split voltage configuration allows for balanced and stable operation of the system, ensuring that both positive and negative power rails are available for effective servo control.
  • A key element of the module is its ability to provide a stable and consistent power output, which is essential for the reliable operation of servo current regulators. Fluctuations in power supply could lead to erratic servo valve behavior, ensures that the voltage levels remain steady, contributing to the precision and accuracy required in high-performance applications.

Servo Current Regulators

  • The servo driver assembly contains two independent servo current regulators. These regulators are responsible for controlling the current that flows through the servo valves, based on input signals received from the system. This dual-regulation feature enhances the control flexibility, allowing the system to manage multiple servo valves with high accuracy, ensuring each valve operates within its designated parameters.
  • The current regulators within the module operate based on current reference signals supplied by the servo pack. These references dictate the desired servo valve positions, and the regulators adjust the current flow accordingly. By maintaining precise current levels, the system ensures the accurate positioning of servo valves, which is critical for controlling the movement of mechanical components in turbines and other equipment. This process directly impacts the performance and efficiency of the overall system, making the regulators a vital part of the servo driver assembly.

Key Features

  • Servo Valve Position Control: Responsible for handling two servo valve position loops, ensuring accurate and reliable positioning of the servo valves.
  • Current Output Selection: It offers a selection of five servo valve output currents ranging from 10 to 120 mA DC. This flexibility allows it to be tailored to various operational requirements and ensures compatibility with a wide range of servo valves.
  • LVDT Excitation and Feedback: It supplies Linear Variable Differential transformer (LVDT) excitation and can accept feedback from up to eight LVDTs. This capability ensures precise measurement and control of valve positions.
    Pulse Rate Inputs: It also accepts two pulse rate inputs from fuel flow meters, which are crucial for accurate monitoring and control of fuel flow within the system.
  • Selection of Gains: The servo driver circuit includes a selection of five configurable gains. These gains can be adjusted to meet specific operational requirements, providing flexibility in different applications.
  • Optimized Performance: Configurable gains allow the system to be fine-tuned for optimal performance, enhancing the precision and reliability of servo valve control.
  • Servo Suicide Relays: The assembly contains servo suicide relays, which are safety mechanisms designed to quickly shut down the servo system in the event of a malfunction or emergency. This feature ensures the protection of both the system and the surrounding environment.
  • Excitation Output Driver Circuits: The inclusion of excitation output driver circuits is essential for providing the necessary excitation signals to the Linear Variable Differential Transformers (LVDTs). These signals are critical for accurate position feedback and control of the servo valves.
