FUNCTION C

O

DES 

Pressurization before slow flowrate stopping (J08 and J09) 

Specifying J08 (Pressurization starting frequency) and J09 (Pressurizing time) enables pressurization control when the 
frequency drops below the level specified by J15 (Stop frequency for slow flowrate) for the period specified by J16. During 
the pressurization, the 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 the pressurization control, see the chart below. 

 

 
 

 

J10 

PID Control (Anti reset windup

 

J10 suppresses overshoot in control with the PID processor. As long as the deviation between the feedback and the PID 
command is beyond the preset range, the integrator holds its value and does not perform integration operation. 

-  Data setting range: 0 to 200 (%)
