Note
The parameter setting value of pressure or flow rate is limited as follows.
(1) High-pressure side pressure setting value ≥ Low-pressure side pressure setting value
(2) Low-pressure side flow rate setting value ≥ High-pressure side flow rate setting value
When the parameter setting value of High-pressure side pressure setting, Low-pressure side
pressure setting, Low-pressure side flow rate setting or High-pressure side flow rate setting
changes, if its setting value reaches the above conditions, every Low-pressure side pressure
setting value or High-pressure side flow rate setting value in (1) or (2) will be automatically
changed as follows.
(1) Low-pressure side pressure setting value = High-pressure side pressure setting value
(2) High-pressure side flow rate setting value = Low-pressure side flow rate setting value
Pressure and flow rate characteristic curve can be set by the parameter as shown in the figure below.

* Please refer to "12.3.3 [P40: PL_D] Settings when operating only at high pressure side (single) " for more
information about how to set the high-pressure and low-capacity operation.

PQ selection
The PQ number can be selected by switching the digital input signal. The pressure command, the flow rate
command which is set by the parameter in advance can be switched.
In addition, the acceleration or deceleration time of pressure / flow rate at the time of switching PQ number also
can be changed.
