7.1.5 Spool position control closed loop for single stage and dual stage
valves
The spool position closed loop mode is selected by setting the parameter <ControlMode> (0x6043) to 2 (spool
position control closed loop).

7.1.6 Pressure control open loop
The pressure control open loop mode is selected by setting the parameter <ControlMode> (0x6043) to 3
(pressure control open loop). The behavior is the same as in the spool position closed loop control mode.

7.1.7 Pressure control closed loop
The pressure control closed loop mode is selected by setting the parameter <ControlMode> (0x6043) to 4
(pressure control closed loop).

The signal #SpoolpositionSetpoint# is an internal signal only. It links the signal from the spool po-
sition setpoint value path to the spool position demand value generator.

This mode is for commissioning of the servo valve only and should only be used by Moog staff..
