7.3.4 Spool position / pilot spool position actual value path
The following parameters contain the spool position depending on the servo valve hardware (single or dual
stage).
7.3.4.1 Object 0x6301: Actual value
This parameter holds the actual value of the spool position.
For a single stage servo valve, the spool position value is scaled and mapped to the signal
<SplActualValue> (0x6301).
For a dual stage servo valve, the spool position value of the main stage is scaled and mapped to the same
signal <SplActualValue> (0x6301).

7.3.4.2 Object 0x3301: Actual value pilot
For a single stage servo valve, the spool position value is scaled and mapped to the signal
<ActualValuePilot> (0x3301).
For a dual stage servo valve, the spool position value of the pilot stage is scaled and mapped to the same sig-
nal <ActualValuePilot> (0x3301).
7.3.4.3 Object 0x3506: Customer Scaling Offset
This parameter allows an offset of ± 5 % to the pilot valve spool position <ActualValuePilot> (0x3301). This
offset may help for example in case of a temperature drift or another drift.
7.3.5 Spool position / pilot spool position controller
For a single stage servo valve the spool position controller controls the spool position. The parameter
<SplControlDeviation> (0x6350) holds the spool position control deviation. Also parameter
<PilotControlDeviation> (0x3302) holds the spool control deviation.
For a dual stage servo valve, this spool controller is used to control the pilots spool position. The main stage is
controlled by the main stage spool position controller. The parameter <SplControlDeviation> (0x6350) holds
the main stage spool position control deviation. The parameter <PilotControlDeviation> (0x3302) holds the pi-
lot stage spool control deviation.
