Bosch Rexroth A6VM series 71 User Manual

16 A6VM series 71 | Axial piston variable motor
EZ – Two-point electric control
EZ – Two-point electric control
The two-point electric control allows the displacement to
be set to either V
g min
or V
g max
by switching the electric
current to a switching solenoid on or off.
Note
The control oil is internally taken out of the high pressure
side of the motor (A or B). For reliable control, an operat-
ing pressure of at least 435psi (30bar) is required in A
(B). If a control operation is performed at an operating
pressure <435psi (30bar), an auxiliary pressure of at least
435psi (30bar) must be applied at port G via an external
check valve. For lower pressures, please contact us.
Please note that pressures up to 7250psi (500bar) can
occur at port G.
Response time damping
The response time damping is influencing the stroke char-
acteristics of the motor and thus the reaction speed of the
machine.
