5464-768 Woodward ProTech 203

The 5464-768 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 5464-768
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:
- 5464-768 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.

Basic requirements
Requirements for servo feed system

1. Wide speed range

2. High positioning accuracy

3. Having sufficient transmission rigidity and high speed stability

4. Quick response, no overshoot

In order to ensure productivity and processing quality, in addition to high positioning accuracy, it is also required to have good fast response

characteristics, that is, the response of tracking command signals should be fast, because the CNC system requires sufficient acceleration and

deceleration during startup and braking, shortening the transition process time of the feeding system and reducing contour transition errors.

5. Low speed high torque, strong overload capacity

Generally speaking, servo drives have an overload capacity of 1.5 times or more within minutes or even half an hour, and can be overloaded by 4 to 6 times in a short period of time without damage.

6. High reliability

The feed drive system of CNC machine tools is required to have high reliability, good working stability, strong environmental adaptability to temperature, humidity, vibration, and strong anti-interference ability.

Requirements for motors

1. The motor can operate smoothly from the lowest speed to the highest speed, with minimal torque fluctuations, especially at low speeds such as

0.1r/min or lower, where there is still a smooth speed without crawling phenomenon.

2. The motor should have a large and long-lasting overload capacity to meet the requirements of low-speed and high torque. Generally, DC servo motors require an overload of 4-6 times within a few minutes without damage.

3. In order to meet the requirements of rapid response, the motor should have a small moment of inertia and a large locked rotor torque, and have the smallest possible time constant and starting voltage.

4. The motor should be able to withstand frequent starting, braking, and reversing.
