6-3-1 Constant Pressure Control Mode
Func. Name Description
F_084
Pressure Boost for
Water Usage Detection
․
Boost the pressure up to detect if the water is used.
F_085
Time Interval of
Pressure Boost for
Water Usage Detection
․
Set the time interval for F_084 to detect if the water
is used.
*0: off
F_086
ON/OFF Mode Starting
Rate Setting
․
In constant pressure control mode and lower water
usage condition, setting the starting rate of drive
switch to ON/OFF mode.
*0: Disable the ON / OFF mode
*The lower setting value means the flow rate
F_115
Acceleration Time of
Pressure Boost
․
Set the time of F_084 (Pressure Boost for Water
Usage Detection) to detect if the water is used.
F_117
Pressure Dead Band
Setting
․ In constant pressure
control mode (F_103≠0), drive
will activate PID control when the feedback signal
exceeds the dead band.
F_133
Drive Stop Frequency
of Water Usage
Detection
․
When the operation frequency is lower than the
setting value, drive will ramp to stop.
1. In constant pressure control mode, drive will auto-detect the water usage according to the
setting of F_084 (Pressure Boost for Water Usage Detection) and F_115 (Acceleration
Time of Pressure Boost) with the time interval of F_085 (Time Interval of Pressure Boost
for Water Usage Detection) to detect the water usage conditions.
