P451 PIN
Mini
Sets the lower limit of the pressure in relation to pressure
command voltage. It prevents reverse rotation of the pump
due to command voltage variations caused by noise or due to
improper operation/input.
e.g.) If the parameter is set to 10 (1.0 %) with a rated pressure
of 17.5 MPa, the minimum pressure is 0.175 MPa
(calculated value).

P452 Q-COMP
Compensates for leakage inside the pump in relation to load
pressure. As load pressure increases, the leakage level in the
pump rises, resulting in lower flow. To prevent this problem, a
compensation value proportional to load pressure is added to
the flow command.
