Used for transmitting a flow request to the PVED-CL. The flow request is converted to a spool position
with dead-band compensation. Use the SetFlow command for black-box testing the PVED-CL flow
characteristic in operational mode without knowledge to the actual dead-band settings.
Open-loop mode converts the flow request directly to the corresponding spool position with dead-band
compensation.
Closed-loop mode converts the flow request as for open-loop mode but adds the programmed closed
loop spool position offset (ClosedLoopXspOffset at parameter index 748) to the spool position. This
allows testing the valve output flow when used in Guidance mode.
