Hydraulic fluids
The A6VE variable motor is designed for operation with HLP
mineral oil according to DIN 51524. Application instructions
and requirements for hydraulic fluids should be taken from
the following data sheets before the start of project planning:
▶ 90220: Hydraulic fluids based on mineral oils and
related hydrocarbons
▶ 90221: Environmentally acceptable hydraulic fluids
▶ 90222: Fire-resistant, water-free hydraulic fluids
(HFDR/HFDU)
▶ 90223: Fire-resistant, water-containing hydraulic fluids
(HFC, HFB)
▶ 90225: Axial piston units for operation with water-free
and water-containing fire-resistant hydraulic fluids
(HFDR, HFDU, HFB, HFC).
The variable motor A6VE is not suitable for operation with
HFA hydraulic fluid. If operating with HFB-, HFC- and HFD or
environmentally acceptable hydraulic fluids, the limitations
regarding technical data or other seals must be observed.
Notes on selection of hydraulic fluid
The hydraulic fluid should be selected such that the operat-
ing viscosity in the operating temperature range is within
the optimum range (ν
opt
see selection diagram).
Notice
At no point of the component may the temperature be
higher than 115°C. The temperature difference specified in
the table is to be taken into account when determining the
viscosity in the bearing.
If the above conditions cannot be met due to extreme
operating parameters,
we recommend the use of a flushing and boost-pressure
valve (see page 25).

Flow direction
Filtration of the hydraulic fluid
Finer filtration improves the cleanliness level of the hydrau-
lic fluid, which increases the service life of the axial piston
unit.
A cleanliness level of at least 20/18/15 is to be maintained
according to ISO4406.
At very high hydraulic fluid temperatures (90°C to maxi-
mum 103°C, measured at portT), a cleanliness level of at
least 19/17/14 according to ISO4406 is necessary.
Effect of case pressure on beginning of control
An increase in the case pressure leads to an increase in the
beginning of control for the HP and HA.T3 controls.
For EP and HA control, an increase in case pressure has no
effect on the beginning of control.
The factory setting for the beginning of control is made at
p
abs
=2bar case pressure.
Flow direction
Direction of rotation, viewed on drive shaft

Shaft seal
Permissible pressure loading
The service life of the shaft seal is influenced by the rota-
tional speed of the axial piston unit and the leakage pres-
sure in the housing (case pressure). Momentary (t < 0.1s)
pressure peaks of up to 10bar are permitted. The service
life of the shaft seal decreases with increasing frequency of
pressure peaks and increasing mean differential pressure.
The case pressure must be equal to or higher than the
ambient pressure.

See diagram
below
To avoid damage to the axial piston motor during operation as a pump
(change of the high-pressure side at constant direction of rotation, e.g. dur-
ing braking processes) a minimum pressure has to be ensured at the working
port (inlet). The minimum required pressure is dependent on the rotational
speed and displacement of the axial piston unit (see characteristic curve).

HP – Proportional hydraulic control
The proportional hydraulic control provides infinite adjust-
ment of the displacement. The control is proportional to
the pilot pressure at port X.

mum permissible rotational speed at minimum pilot

▶ Beginning of control at V

mum rotational speed at minimum pilot pressure).
▶ End of control at V
g min
(minimum torque, maximum
permissible rotational speed, at maximum pilot pressure).
Notice
▶ Maximum permissible pilot pressure: p
St
= 100bar
▶ The control oil is internally taken out of the high pres-
sure side of the motor (A or B). For reliable control, a
working pressure of at least 30bar is required in A (B).
If a control operation is performed at a working pres-
sure <30bar, an auxiliary pressure of at least 30bar
must be applied at port G using an external check valve.
For lower pressures, please contact us.
Bear in mind that pressures up to 450bar can occur at
port G.
▶ Specify the desired beginning of control in plain text
when ordering, e.g. beginning of control at 10bar.
▶ The beginning of control and the HP characteristic curve
are influenced by the case pressure. An increase in the
case pressure
causes an increase in the beginning of
control (see page6)
and thus a parallel displacement
of the characteristic curve.
▶ A leakage flow of maximum 0.3l/min can occur at port X
due to internal leakage (working pressure > pilot pres-
sure). The control is to be suitably configured to avoid
an independent build-up of pilot pressure.

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

The beginning of control of the A6VE motor with HA control
is V

The control device measures internally the working pres-
sure at A or B (no control line required) and upon reaching
the beginning of control, the controller swivels the motor
from V

Flushing and boost-pressure valve
The flushing and boost-pressure valve is used to remove
heat from the hydraulic circuit.
In a closed circuit, it is used for flushing the case and safe-
guarding the minimum boost pressure.
Hydraulic fluid is directed from the respective low pressure
side into the motor housing. This is then fed into the reser-
voir, together with the leakage. In the closed circuit, the
removed hydraulic fluid must be replaced by cooled hydrau-
lic fluid supplied by the boost pump.
The valve is mounted on the port plate or integrated
(depending on the control type and size).

BVD and BVE counterbalance valves

BVD and BVE counterbalance valves
Function
Counterbalance valves for travel drives and winches should
reduce the danger of overspeed and cavitation in open
circuits of axial piston motors. Cavitation occurs if, during
braking, when going downhill or during the load-lowering
process, the motor speed is greater than it should be for
the given inlet flow and thus the supply pressure collapses.
If the supply pressure falls below the value specified for the
relevant counterbalance valve, the counterbalance spool
moves into the closed position. The cross-sectional area of
the counterbalance valve return duct is then reduced,
creating a bottleneck in the return flow of the hydraulic
fluid. The pressure increases and brakes the motor until the
rotational speed of the motor reaches the specified value
for the given inlet flow.
Notice
▶ BVD available for sizes 55 to 200 and BVE available for
sizes 107 to 200.
▶ The counterbalance valve must be ordered additionally.
We recommend ordering the counterbalance valve and
the motor as a set.
Order example: A6VE080HA1T30004A/65MWV0Y2Z
97W0-0 + BVD20F27S/41B–V03K16D0400S12
▶ For safety reasons, controls with beginning of control at
V
g
min
(e.g. HA) are not permissible for winch drives!
▶ Counterbalance valves must be optimized during proto-
type commissioning to prevent unacceptable operating
conditions and compliance with the specification must
be verified.
▶ The counterbalance valve does not replace the mechani-
cal service brake and holding brake.
▶ Observe the detailed notes on the BVD counterbalance
valve in RE95522 and BVE counterbalance valve in
RE95525.
▶ For the design of the brake release valve, we require the
following data for the mechanical holding brake:
– the cracking pressure
– the volume of the counterbalance spool between
minimum stroke (brake closed) and maximum stroke
(brake released with 21bar)
– the required closing time for a warm device

Mounting of the counterbalance valve
When delivered, the counterbalance valve is fastened to the
motor with two tacking screws (transport lock). The tack-
ing screws may not be removed while mounting the working
lines! If the counterbalance valve and motor are delivered
separately, the counterbalance valve must first be fastened
to the motor port plate using the provided tacking screws.
The counterbalance valve is finally mounted to the motor by
fitting the SAE flange
The screws to be used and the instructions for mounting
can be found in the instruction manual.

Speed sensor
35
Speed sensor
The A6VE...U version (“prepared for speed sensor”, i.e.
without sensor) is equipped with a spline on the rotary
group.
A signal proportional to the rotational speed of the motor
can be generated with the mounted DSA speed sensor.
The DSA sensor registers the rotational speed and direction
of rotation.
Type code, technical data, dimensions and parameters for
the connector, plus safety instructions about the sensor
can be found in the relevant data sheet 95133–DSA. The
sensor is mounted on the port provided specially for this
with a mounting bolt. On deliveries without sensor, the
port is plugged with a pressure-resistant cover.
We recommend ordering the A6VE variable motor complete
with mounted sensor.

Installation instructions
Installation instructions
The axial piston unit must be filled with hydraulic fluid and
air bled during commissioning and operation. This must
also be observed following a longer standstill as the axial
piston unit may empty via the hydraulic lines.
The leakage in the housing area must be directed to the
reservoir via the highest drain port (T
1
, T
2
).
For combinations of multiple units, make sure that the
respective case pressure in each unit is not exceeded. In
the event of pressure differences at the drain ports of the
units, the shared drain line must be changed so that the
maximum permissible case pressure of all connected units
is not exceeded at any operational conditions. If this is not
possible, separate drain lines must be laid.
To achieve favorable noise values, decouple all connecting
lines using elastic elements and avoid above-reservoir
installation.
In all operating conditions, the drain line must flow into the
reservoir below the minimum fluid level.
Notice
In certain installation positions, an influence on the con-
trol or closed loop control can be expected. Gravity, dead
weight and case pressure can cause minor characteristic
shifts and changes in response time.

Project planning notes
Project planning notes
▶ The motor A6VE is designed to be used in open and
closed circuits.
▶ The project planning, installation and commissioning of
the axial piston unit requires the involvement of quali-
fied skilled personnel.
▶ Before using the axial piston unit, please read the cor-
responding instruction manual completely and thor-
oughly. If necessary, these can be requested from Bosch
Rexroth.
▶ Before finalizing your design, please request a binding
installation drawing.
▶ The specified data and notes contained herein must be
observed.
▶ For safety reasons, controls with beginning of control at
V
g min
(e.g. HA) are not permissible for winch drives,
e.g. anchor winches.
▶ Depending on the operating conditions of the axial
piston unit (working pressure, fluid temperature), the
characteristic curve may shift.
▶ Preservation: Our axial piston units are supplied as
standard with preservative protection for a maximum of
12 months. If longer preservative protection is required
(maximum 24 months), please specify this in plain text
when placing your order. The preservation periods apply
under optimal storage conditions, details of which can
be found in the data sheet 90312 or the instruction
manual.
▶ Not all versions of the product are approved for use in a
safety function according to ISO13849. Please consult
the responsible contact person at Bosch Rexroth if you
require reliability parameters (e.g. MTTF
d
) for functional
safety.
▶ Depending on the type of control used, electromagnetic
effects can be produced when using solenoids. When a
direct current is applied, solenoids do not cause electro-
magnetic interference nor is their operation impaired by
electromagnetic interference.
Other behavior can result when a modulated direct
current (e.g. PWM signal) is applied. Potential electro-
magnetic interference for persons (e.g. persons with a
pacemaker) and other components must be tested by
the machine manufacturer.
▶ Please note the details regarding the tightening torques
of port threads and other threaded joints in the instruc-
tion manual.
▶ Working ports:
– The ports and fastening threads are designed for the
specified maximum pressure. The machine or system
manufacturer must ensure that the connecting ele-
ments and lines correspond to the specified applica-
tion conditions (pressure, flow, hydraulic fluid, tem-
perature) with the necessary safety factors.
– The working ports and function ports are only
intended to accommodate hydraulic lines.

Safety instructions
▶ During and shortly after operation, there is a risk of
getting burnt on the axial piston unit and especially
onthe solenoids. Take appropriate safety measures
(e.g. by wearing protective clothing).
▶ Moving parts in control equipment (e.g. valve pistons)
can, under certain circumstances get stuck in position
as a result of contamination (e.g. impure hydraulic fluid,
abrasion, or residual dirt from components). As a result,
the hydraulic fluid flow and the build-up of torque in the
axial piston unit can no longer respond correctly to the
operator's specifications. Even the use of various filter
elements (external or internal flow filter) will not rule
out a fault but merely reduce the risk.
The machine/system manufacturer must test whether
remedial measures are needed on the machine for the
application concerned in order to set the consumer
being driven to a safe position (e.g. safe stop) and if
necessary to ensure it is properly implemented.
▶ Moving parts in high-pressure relief valves may in certain
circumstances become stuck in an undefined position
due to contamination (e.g. contaminated hydraulic
fluid). This can result in restriction or loss of the load
holding function in lifting winches.
The machine/system manufacturer must check whether
additional measures are required on the machine for the
relevant application in order to keep the load in a safe
position and ensure they are properly implemented.
▶ When using the axial piston motor in winch drives, make
certain that the technical limit values are not exceeded
under all operating conditions. If the axial piston motor
is extremely overloaded (e.g. if the maximum permis-
sible rotational speeds are exceeded during weighing of
the anchor while the ship is in motion), the rotary group
may be damaged and, in the worst case, the axial piston
motor may burst. The machine manufacturer / system
manufacturer is to undertake additional measures, up to
and including encapsulation.
