Bosch Rexroth A6VM series 71 - HP Control: Pressure Control and Fixed Setting; HP5 D1;HP6 D1: Pressure Control with Fixed Setting

Bosch Rexroth Corp., RE-A 91610/12.2015
12 A6VM series 71 | Axial piston variable motor
HP – Proportional hydraulic control
HP5D1, HP6D1 Pressure control, fixed setting
The pressure control overrides the HP 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)
