5.4 Details of Function Codes
5-224
For the slow flowrate stopping function, see the following chart.

Pressurization before slow flowrate stopping (J08 and J09)
Specifying Pressurization starting frequency (J08) and Pressurizing time (J09) enables pressurization control
when the frequency drops below the level specified by Stop frequency for slow flowrate (J15) for the period
specified by (J16). During the pressurization, PID control is in the hold state.
This function prolongs the stopping time of equipment with a bladder tank by pressurizing immediately before
the frequency drops below the level at which the inverter stops the motor, thus enabling energy saving
operation.
Because the pressurization starting frequency (J08) can be specified with a parameter, pressurization setting
suitable for the equipment is possible.
For pressurization control, see the chart below.
