Page 20: Proportional (Required)
This term eliminates the difference between the programmed set speed and the actual speed. The integral gain changes the time it takes to drive the error to zero. Note: Integral is needed to eliminate speed offsets due to proportional gain and should never be left at zero. Woodward... -
Page 21: Derivative (Required)
This overall gain acts as the multiplier on the three PID terms (proportional, integral, derivative) when the Idle Speed is the active target speed. The idle speed set point is active only during startup when the idle hold timer is running. This gain term is adjustable from 01 to 99. Woodward... -

IDLE SPEED. After the IDLE HOLD TIME expires the controller then uses the ACCEL RATE to ramp the engine to the selected set speed (REMOTE SPEED POT or SET SPEED A). The startup sequence is complete once the engine speed reaches the selected set speed. Woodward... -
Page 23: Accel Rate (Optional)
The startup rate specifies how fast the controller should increase the engine speed when the engine is started. The rate value indicates Hertz per second. The formula to use for determining a precise Startup Rate is shown below. [(final_target_speed_in_Hertz) – (crank_speed_in_Hertz)] / (ramp_time_in_seconds) = startup_rate_value Woodward... -
Page 24: Startup Limit (Optional)
The default value of 1000 allows the actuator drive signal to use 100.0% of available current. Decreasing the value limits the available drive signal thereby limiting how far open the actuator can go. Increasing the value allows the actuator to open further. Woodward... -

Page 29: Duty Cycle Limit (Optional)
If the Startup Speed value is set too high (above the active set speed) then the Startup Speed becomes the target speed that the controller must reach before the controller considers the startup sequence complete. Typically, the startup sequence ends when the engine speed reaches the active set speed. The active Woodward... -

Page 32: Chapter 4. Universal Pst
Introduction The Universal Parameter Setup Tool (Universal PST) is a Microsoft® Windows® application available from Woodward that enables you to adjust controller parameter settings and monitor controller operation. Universal PST also includes a graphical chart recorder that displays engine speed in real-time. This provides a visual representation of how the engine speed changes in response to changes in load, which can be very helpful when tuning the controller. -
