Function and Working Principle
The 5439-986 Speed Controller maintains a desired rotational speed through closed-loop control:
- Reads speed feedback from sensors (e.g., magnetic pickups)
- Compares actual speed with target setpoint
- Sends corrective signals to actuators or fuel control systems
- Maintains stable speed under varying load conditions
This ensures precise speed regulation and protects equipment from mechanical stress caused by overspeed or underspeed.
