5464-536 WOODWARD Debugger unit

The 5464-536 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 5464-536
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:
- 5464-536 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.

4. Feedback compensation type semi closed loop control
This servo drive control compensation principle is the same as the open-loop compensation system, consisting of two independent

measurement systems consisting of a rotary transformer and an induction synchronizer,

both of which work in amplitude discrimination mode. The disadvantage of this system is high cost, requiring two sets of detection systems.

The advantage is that it is easier to adjust than a fully closed-loop system, has good stability, and is suitable for use as a feed drive for

high-precision large CNC machine tools.

Servo drive maintenance
1. When checking the current monitoring output terminal of the driver with an oscilloscope, it was found that it was all noise and could not be read out.

Fault cause: The current monitoring output terminal is not isolated from the AC power supply (transformer).

Solution: You can use a DC voltmeter to detect and observe.

2. The motor runs faster in one direction than in another.

Reason for malfunction: The phase of the brushless motor is incorrect.

Solution: Check or identify the correct phase.

Reason for malfunction: When not in use for testing, the test/deviation switch is turned to the testing position.

Solution: Turn the test/deviation switch to the deviation position.

Reason for malfunction: The position of the deviation potentiometer is incorrect.

Solution: Reset.

3. Motor stall.

Reason for malfunction: The polarity of the speed feedback is incorrect.
