Hydraulic fluidBefore starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally ac-ceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions.

The (A)A6VM variable motor is not suitable for operation with HFA. If HFB, HFC and HFD or environmentally acceptable hy-draulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed.

When ordering, please indicate the used hydraulic fluid.

Operating viscosity range

For optimum efficiency and service life, select an operating vis-cosity (at operating temperature) within the optimum range of

νopt = optimum operating viscosity 80...170 SUS (16 to 36 mm2/s)

depending on the circuit temperature (closed circuit) and tank temperature (open circuit).

Limits of viscosity range

The limiting values for viscosity are as follows:

Sizes 28 to 200:

νmin = 42 SUS (5 mm2/s)short-term (t < 3 min) at max. perm. temperature of tmax = +240°F (+115°C)

νmax = 7400 SUS (1600 mm2/s)short-term (t < 3 min) at cold start (p ≤ 435 psi / 30 bar, n ≤ 1000 rpm, tmin = -40°F / -40°C)Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.

Sizes 250 to 1000:

νmin = 60 SUS (10 mm2/s)short-term (t < 3 min) at max. perm. temperature of tmax = +195°F (+90°C)

νmax = 4600 SUS (1000 mm2/s)short-term (t < 3 min) at cold start (p ≤ 435 psi / 30 bar, n ≤ 1000 rpm, tmin = -13°F / -25°C)Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.

Note that the maximum hydraulic fluid temperature of 240°F (115°C) (+195°F / +90°C for size 250 to 1000) must not be ex-ceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 22°F (12 K) higher than the average case drain temperature.

Special measures are necessary in the temperature range from - 40°F and -13°F (-40°C and -25°C). Please contact us.

For detailed information about use at low temperatures, see RE 90300-03-B.

Details regarding the choice of hydraulic fluid

The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature, in an open circuit the tank temperature.

The hydraulic fluid should be chosen so that the operating vis-cosity in the operating temperature range is within the optimum range (νopt.) - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case.

Example: At an ambient temperature of X°C an operating temperature of 140°F (60°C) is set. In the optimum operating viscosity range (νopt; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68.

Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the circuit temperature or tank temperature. At no point in the system may the temperature be higher than 240°F (115°C) for sizes 28 to 200 or 195°F (90°C) for sizes 250 to 1000.

If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U or using a flush and boost pressure valve (see pages 66-67).

Technical data


Technical dataFiltrationThe finer the filtration, the higher the cleanliness level of the hy-draulic fluid and the longer the service life of the axial piston unit.

To ensure functional reliability of the axial piston unit, the hydrau-lic fluid must have a cleanliness level of at least

20/18/15 according to ISO 4406.

At very high hydraulic fluid temperatures (195°F to max. 240°F / 90°C to max. 115°C) at least cleanliness level

19/17/14 according to ISO 4406 is required.

If the classes specified above cannot be maintained, please contact us.

Shaft seal ringPermissible pressure load

The service life of the shaft seal ring is affected by the speed of the motor and the case drain pressure. It is recommended that the average, continuous case drain pressure at operating temperature 45 psi (3 bar) absolute not be exceeded (max. permissible case drain pressure 90 psi (6 bar) absolute at reduced speed, see dia-gram). Short-term (t < 0.1 s) pressure spikes of up to 145 psi (10 bar) absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes.

The case pressure must be equal to or greater than the external pressure on the shaft seal ring.

HD - Hydraulic control, pilot-pressure relatedThe pilot-pressure related hydraulic control permits infinite control of the displacement according to the pilot-pressure signal. The displacement is proportional to the pilot pressure applied to port X.

Standard configuration:

– Start of control at Vg max (max. torque, min. speed)

– End of control at Vg min (min. torque, max. permitted speed)

Please note:

– Maximum permissible pilot pressure: 1450 psi (100 bar)

– For reliable control, an operating pressure of at least 435 psi (30 bar) is necessary in A (B). If a control operation is perfor-med 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. Lower pressures may be adequate in individual cases.

– Please state the desired start of control in plain text when ordering, e.g.: start of control at 145 psi (10 bar).

The following only applies to sizes 250 to 1000:

– The start of control and the HD characteristic are influenced by the case pressure. An increase in the case pressure causes an increase in the start of control (see page 6) and thus a parallel displacement of the characteristic.

– Fluid escapes from port X at the rate of max. 0.08 gpm (0.3 l/min) due to internal leakage (operating pressure > pilot pressure). To prevent a build-up in pilot pressure, port X must be vented to tank.

HD1 pilot pressure increase ΔpS = 145 psi (10 bar)An increase in pilot pressure of 145 psi (10 bar) on port X causes a reduction in the displacement from Vg max to 0 cm3

(sizes 28 to 200) or from Vg max to 0.2 Vg max (sizes 250 to 1000).

Note

The spring return feature in the control unit is not a safety device

The spool valve inside the control unit can get stuck in an undefined position by internal contamination (contamina-ted hydraulic fluid, abrasion or residual contamination from system components). As a result, the axial piston unit can no longer supply the flow specified by the operator.

Check whether your application requires that remedial mea-sures be taken on your machine in order to bring the driven consumer into a safe position (e. g. immediate stop).

HD - Hydraulic control, pilot-pressure relatedHD.D Pressure control, directThe pressure control overlays the HD function. If the load incre-ases, or a reduction in the swivel angle of the motor causes the system pressure to increase, the motor will start to swivel to a greater angle when the pressure reaches the setpoint value of the pressure control.

The increase in the displacement and the resulting reduction in pressure cause the control deviation to decrease. With the in-crease in displacement the motor develops more torque, while the pressure remains constant.

HD.G Pressure control, remote

Sizes 250 to 1000

When the set pressure value is reached, the remote pressure control regulates the motor continuously up to the maximum displacement Vg max. A pressure-relief valve (not supplied) controls the internal pressure cut-off valve. The pressure-relief valve is separate from the motor and is connected to X3. As long as operating pressure is below the set point of the external pressure-relief valve (1150 – 5100 psi / 80 – 350 bar), the pressure is equal on both sides of the internal pressure cut-off valve, and spring force keeps it closed. The external relief valve opens when the operating pressure exceeds the set point, and the pressure on the spring end of the pressure cut-off valve is reduced.The pressure cut-off valve then modulates the motor displace-ment (i.e.-swivelling towards maximum displacement) to limit operating pressure.

The standard differential pressure setting of the internal pressure cut-off valve is 365 psi (25 bar). We recommend the following for use as the external (i.e.-remote control) pressure-relief valve:

HA - Automatic control, high-pressure relatedWith the automatic high-pressure related control, the motor displacement is adjusted automatically depending on the ope-rating pressure.

The control unit internally measures the operating pressure atA or B (no control line required) and, when the pressure reaches the set pressure value, the controller swivels the motor with increasing operating pressure from Vg min to Vg max.

Standard configuration HA1, HA2:

Start of control at Vg min (min. torque, max. speed)End of control at Vg max (max. torque, min. speed)

Please note:

– For safety reasons, winch drives are not permissible with start of control at Vg min (standard for HA).


– The start of control and the HA characteristic are influenced by the case pressure. An increase in the case pressure causes an increase in the start of control (see page 6) and thus a parallel displacement of the characteristic. Only with HA1, HA2, HA.T, HA.R, HA.U (sizes 250 to 1000) and with HA1T (sizes 28 to 200).


– Fluid escape from port X at the rate of 0.08 gpm (0.3 l/min) due to internal leakage (operating pressure > pilot pressure). To prevent a build-up in pilot pressure, port X must be vented to tank.Only with HA.T control.

HA - Automatic control, high-pressure related (override)

HA.T Hydraulic override of pressure settingWith the HA.T control, the start of control can be influenced by applying a pilot pressure to port X.

For each 15 psi (1 bar) of pilot pressure, the start of control is reduced by 250 psi (17 bar) for sizes 28 to 200 or 115 psi (8 bar) for sizes 250 to 1000.

Examples (sizes 28 to 200):

Start of control adjustment 4350 psi (300 bar) 4350 psi (300 bar)

Pilot pressure at port X 0 psi (0bar) 145 psi (10 bar)

Start of control at 4350 psi (300 bar) 1885 psi (130 bar)

Note:

– Max. permissible pilot pressure 1450 psi (100 bar)

HA.U1, Electric override ofHA.U2 pressure settingWith the HA.U1 or HA.U2 control, the start of control can be overridden by an electric signal to an switching solenoid. When the over-ride solenoid is energized, the variable motor swivels to the maximum swivel angle without stopping at an intermedi-ate position. The start of control can be set to between 1160 and 4350 psi (80 and 300 bar) (specify required setting in clear text when ordering).

HA.R1, Electric override of HA.R2 pressure setting, with elect. travel direction valve (see page 25)With the HA.R1 or HA.R2 control, the high-pressure related closed loop control can be overridden by an electric signal to switching solenoid b. When the over-ride solenoid is energized, the variable motor swivels to the maximum swivel angle without stopping at an intermediate position.

The travel direction valve ensures that the preselected pressure side of the hydraulic motor always controls the swivel angle, even if the high-pressure side changes (e.g. travel drive during a descent). This therefore prevents an undesirable swiveling of the variable motor to a larger displacement.

Depending on the direction of rotation (direction of travel), the travel direction valve (see page 25) can be actuated through the pressure spring or switching solenoid a.

DA - Hydraulic control, speed relatedThe (A)A6VM variable motor with speed-related hydraulic con-trol is best used for hydrostatic drives in combination with the AA4VG variable pump with DA control.

The pilot pressure derived from the drive speed of the AA4VG variable pump, together with the operating pressure, regulate the swivel angle of the hydraulic motor.

Increasing drive speed, i.e. increasing pilot pressure, causes the motor to swivel to a smaller displacement (lower torque, higher speed), depending on the operating pressure.

If the operating pressure increase above the pressure setting of the controller, the variable motor swivels to a larger displace-ment (higher torque, lower speed).

The design of a drive with DA control must be carried out using the technical data relating to the AA4VG variable pump with DA control.

Detailed information can be obtained from our sales depart-ments and on the Internet at www.boschrexroth.com/da-control.

Please note:

– The start of control and the DA characteristic are influenced by the case pressure. An increase in the case pressure causes a drop in the start of control (see page 6) and thus a parallel displacement of the characteristic.

Application in travel drives in closed circuits. The travel direc-tion valve of the motor is switched using the 4/3-directional valve on the control device of the driving pump.

When the pump (AA4VG, AA10VG) is switched to the neutral position or into reverse, the vehicle may experience impulsive braking depending on the vehicle's mass and current speed.

This impulsive braking is prevented through the use of the following electric circuit.

With this control, when the pump (AA4VG, AA10VG) is switched1. to the neutral position: the previous travel direction is retained.2. to reverse: the motor switches to the other travel direction following a time delay (approx. 0.8 s) with respect to the pump.

The flush and boost pressure valve is used to remove heat from the closed circuit and to ensure that a minimum boost pressure is present (opening pressure 230 psi (16 bar), fixed; note when setting primary valve). A side effect is flushing of the case.

Warm hydraulic fluid is removed from the respective low pres-sure side into the motor case. This is then fed into the tank, together with the case drain fluid. The hydraulic fluid drawn out of the closed circuit in this way must be replaced by cooled hydraulic fluid that is pumped in by the boost pump.

In the open circuit, the flush and boost pressure valve is used solely to flush the case from the return line.

The valve is mounted to the variable motor or integrated into the control unit (depending on the type of control and the size).

Orifices can be used to adjust the flushing volumes as required.

Standard flushing volumes (at low pressure ΔpLP = 365 psi (25 bar))

The flushing volume without orifice is approx. 3.17 to 3.70 gpm (12 to 14 l) at low pressure ΔpLP = 365 psi (25 bar).

BVD counterbalance valve (sizes 55 to 160)

FunctionDriving/winch counterbalance valves are designed to reduce the danger of overspeeding and cavitation of axial piston motors in open circuits. Cavitation occurs if the motor speed is greater than it should be for the given flow during braking, downhill travel or decrease in motor load.

Please note

– The BVD counterbalance valve must be specified explicitly in the order. We recommend ordering the counterbalance valve and the motor as a set. Ordering example: AA6VM80HA1T/63W–VSC380A + BVD20F27S/41B–V03K16D0400S12

– For safety reasons, winch drives are forbidden with start of control at Vg min (e.g. HA)!

– The counterbalance valve does not replace the mechanical service brake and parking brake.

– Note the detailed information about the BVD counterbalance valve in RE 95522

Driving counterbalance valve BVD...F Winch counterbalance valve BVD...WExample of application

– Travel drive on wheeled excavators

Typical applications

– Winch drives in cranes

– Track drive in excavator crawlers

BVD counterbalance valve (sizes 55 to 160)

Attaching the counterbalance valveWhen delivered, the counterbalance valve is attached to the motor using 2 tacking screws. Do not remove the tacking screws when connecting the service lines. If the counterbalan-ce valve and motor are delivered separately, the counterbalan-ce valve must first be attached to the motor port plate using the provided tacking screws. In both cases, the final attachment of the counterbalance valve to the motor is by the connectio of the service lines, e.g. using SAE 4-bolt flanges. A total of 6 screws with thread lengths B1+B2+B3 and 2 screws with thread lengths B3+B4 are required.

When tightening the screws, it is imperative that the sequence 1 to 8 (as shown in the adjacent diagram) be adhered to and carried out in two phases.

In the first phase the screws should be tightened to 50% of their tightening torque before being tightened to maximum tightening torque in the second phase (see table below).

The (A)A6VM...D and (A)A6VM...F ("prepared for speed measurement", i.e. without sensor) versions have teeth on the rotary group. The rotating, toothed rotary group generates a signal in proportion to the speed. The signal is picked up by a sensor and can be forwarded for evaluation.

Note

– For sizes 28 to 200 with speed measurement, only port T2 may be used to drain the case drain.

Version "D" (NG 28 to 200)Suitable for mounting the inductive speed sensor ID (see RE 95130). The ID sensor is screwed into the upper case drain port T1. The spacer ring (sizes 28 to 107) or threaded-reducing connector stud (sizes 140 to 200) required for the inductive speed sensor ID is included in the supply volume of the sensor (only when ordering, speed sensor with installation parts).

Version "F" (NG 55 to 500)Suitable for mounting the HDD Hall-effect speed sensor (see RE 95135). With sizes 55 to 200, the HDD sensor is flanged onto the upper case drain port T1; with size 250 to 500, it is flanged onto the port provided for this purpose with two fixing screws. In the standard version, the port is plugged with a pressure-resistant flange cover.

We recommend ordering the (A)A6VM variable motor comple-te with mounted sensor. Please specify the ordering code for the sensor separately.

General

During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled.This is also to be observed following a relatively long standstill as the system may empty via the hydraulic lines.

The case drain inside the case interior must be drained to the tank via the highest case drain port.

In all operating states, the case drain line must flow into the tank below the minimum fluid level.

Installation position

See examples below. Additional installation positions are available upon request.

Below-tank installation (standard)

Motor below the minimum fluid level of the tank.

Recommended installation positions: 1 and 2.

Above-tank installation

Motor above the min. fluid level of the tank

– Note: Installation position 8 (shaft up)

In this installation position, if the case interior is only partially drained, lubrication of the bearings will no longer be ade-quate. A check valve (opening pressure 7.25 psi (0.5 bar)) in the case drain line can prevent the system emptying through the case drain line.
