As the main braking system of wind turbines, the FP009 series pitch system achieves maximum wind energy capture through precise control of blade pitch angles while effectively reducing the overall load of the turbine.

Multiple Safety Protection Mechanisms: A strategy prioritizing turbine feathering attempts safe feathering even after severe driver failures. Core driver chips are equipped with built-in watchdog circuits and dual-core verification, allowing independent execution of feathering commands even if the main control chip crashes. A sensorless observation algorithm maintains blade angle control accuracy of ±0.5° even when the encoder fails.

The pitch system incorporates a built-in EMI filtering unit to handle complex grid conditions such as voltage dips/surges, frequency deviations, and grid harmonics. Supports seamless switching between high-voltage ride-through and low-voltage ride-through modes. Built-in anti-typhoon strategies ensure turbine safety during typhoons, and an active suppression algorithm combats vortex-induced vibrations.
