7.3.5.1 Object 0x6350: Control deviation
The control deviation is the difference between the setpoint value and the actual value. In case of a dual stage
servo valve this parameter holds the control deviation of the main stage spool position.
Chapter "2.4.3 Units and prefix parameter", page 12
7.3.5.2 Object 0x3302: Pilot Control deviation
The pilot control deviation is the difference between the setpoint value and the actual value. In case of a dual
stage servo valve, this parameter holds the control deviation of the pilot spool position. In case of a single
stage valve, this parameter has the same value as <SplControlDeviation> (0x6350).
7.3.5.3 Object 0x2416: Integrator Test Value
This parameter holds the controller output of the I-part of the pilot spool position controller.
7.3.5.4 Object 0x241F: Customer Overall Gain
This gain is accessible for the customer. It will be multiplied to the output of the pilot spool position controller.
(Gain over all of this controller.)
7.3.6 Main stage spool position actual value path
If a dual stage servo valve is used, the main stage spool position value is scaled and mapped to the signal
<ExternalLVDTActualValue> (0x3235) and the signal <SplActualValue> (0x6301).
