EP5D1, EP6D1 Pressure control, fixed setting
The pressure control overrides the EP control function. If
the load torque or a reduction in motor swivel angle causes
the system pressure to reach the setpoint value of the
pressure control, the motor will swivel towards a larger
displacement.
The increase in the displacement and the resulting reduc-
tion in pressure cause the control deviation to decrease.
With the increase in displacement the motor develops more
torque, while the pressure remains constant.
Setting range of the pressure control valve 1150 to 6500 psi
(80 to 450 bar)
