Table1
Set the conditions of the motor speed
when switching to single mode from
confluence.
When the confluence flow rate drops
from the parameter ”high-pressure side
flow rate setting” over this parameter, the
pump will change to single mode.
If the pump switches between confluence
and single mode frequently, please set a
large value to avoid the unstable state.
−
P31 P_SN
Pressure sensor
ratings
1 〜 35[MPa]
35
Setting the rated pressure of the pressure
sensor.
Usually it is not necessary to change the
settings.
−
P32 S_TM
Surge less start-up
time
0.01
〜
9.99[sec] 0.5
Setting the start-up time from the motor
stop to start-up.
Increasing the value can prevent the
rising surge. But the response time of
start-up will be longer.
12-16
P33 L_IN
Motor start initial
response gain
1 〜 999
10
Setting the output of the motor at the time
of start-up.
Decreasing the value can prevent the
rising surge. But the response time of
start-up will be longer.

Setting the pressure conditions to
determine the alarm “E64: Dry running
abnormality”.
−
P36 DR_T
Dry running
judgment time
0.01 〜 9.99[sec]
3
Setting the time of determining the alarm
“E64: Dry running abnormality”.
−
P37 SM_R
Same pressure
confluence rate
0
〜
100[%] 80
Set the switching pressure from
confluence to single mode, by the ratio to
the parameter “low-pressure side pressure
set”. If the pressure decreases over this
setting value, pump will switch to
confluence mode.
Only when the difference between tow
parameters "low-pressure side pressure
set" and "high-pressure side pressure
setting" is 0.5 [MPa] or less, this
parameter will be enabled.
If the pump switches between confluence
and single mode frequently, please set a
small value to avoid the unstable state.
−
0.00 〜 1.00[MPa]
0.5
P38 P_DF
Pressure switch
output dead zone 0
〜 145[×10 PSI] 7.2
Setting the pressure threshold value for
determining the pressure return, after the
pressure switch being actuated.
Setting by the difference of the positive
direction for:" P01: pressure switch".
