surge pressure is more likely to occur.
In addition, if set to 0, the acceleration
response gain will become the maximum
that is defined by the controller. And the
acceleration time will become the
minimum.

After switching the PQ pattern, it will
change the pressure command or the flow
rate command after a delay determined
by this parameter.
Please adjust it, if you want to change
pressure or flow rate, and avoid the
instability in switching solenoid valve.
