When both the pressure command and flow command activate the machine to start from idle,
the flow starts to output. However, due to the slower response of the valve in the
the sudden surge of the pressure may occur. The pressure may recover to normal till the valve
is fully opened. To avoid the aforementioned effect, set this parameter to increase time for the
flow output delay.
