This mode is used to set a pressure, flow
rate, acceleration time and deceleration
time for each P-Q selection No.
Set the following items in this order:
PH <Pressure setting of high-pressure pump
(single mode)>
qH <Flow rate setting of high-pressure pump
(single mode)>
PL <Pressure setting of low-pressure pump
(combination mode)>
qL <Flow rate setting of low-pressure pump
(combination mode)>
Ut <Acceleration time setting>
: Increases in both pressure and speed
(flow rate) are simultaneously specified.
dt <Deceleration time setting>
: Decreases in both pressure and speed
(flow rate) are simultaneously specified.
* For parameters [P23] through [P28], P-Q
selection Nos. are expressed by hexadecimal
numbers.
Example)
When P-Q selection No. is "11":
PH.b, qH.b, PL.b, qL.b, Ut.b, dt.b

High/Low switching
response time
0.30
0.05to1.00
sec
Used to adjust the minimum response time for
switching the solenoid valve when the pump
operation is unstable because the operating point
is close to the high pressure/low pressure
switching point (solenoid valve switching
point).

unstable because the operating point is close to
the high pressure/low pressure switching point
(solenoid valve switching point).
