5403-977 Woodward speed control module

The 5403-977 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5403-977
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5403-977 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

2. Speed control and acceleration control

The motion controller speed control can be used alone or combined with position control to form a dual loop control, but the main loop is position control, and speed control serves as feedback correction to improve the dynamic performance of the system.

3. Synchronous control

Synchronous control of motion controller refers to the synchronous motion control of speed or position of two or more axes, such as system control with electronic gearbox and electronic cam functions. Some require not only simultaneous startup, but also position synchronization, which requires high synchronization accuracy.

4. Force and torque control

The coiler for plastic film, steel strip, cloth, and paper is controlled by constant tension. In situations such as tightening nuts and automatic drilling of automatic assembly machines, the motion controller should adopt synchronous control of torque and position.

Composition architecture of motion control system
A motion controller is used to generate trajectory points (expected output) and a closed position feedback loop. Many controllers can also close a speed loop internally.
