This rate specifies how fast the controller should increase the engine’s speed when a new higher target speed is made active. The parameter value is specified in MPU (magnetic pickup) Hz per second based on the following formula.

Increasing the value allows the actuator to open further. The value assigned to the torque limit parameter is in units of one-tenth of a percent of the actuator’s maximum current feedback reading.

Page 29: 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. -

Page 39: Droop Calibration Procedure
To use Droop, a calibration sequence must be done first. On DPG-2201-001 Models the calibration sequence can be done only by using the controller’s built-in user interface. On DPG-2201-002 Models the calibration sequence can be done by using either the controller’s built-in user interface or Universal PST.
