Settings 0~1000ms
Ramp the flow value for the flow command so as to reduce the vibration of the machine.
Set the time required for ramping the flow from 0~the maximum flow (01-02).

Valve opening delay time

Settings 0 – 200ms
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
hydraulic circuit, 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.
