Technical DataPressure fluid
Before starting project planning, please refer to our datasheets RA 90220 (mineral oil), RA 90221 (environmentally-friendly pressure fluids) and RA 90223 (HF pressure fluids) fordetailed information regarding the choice of pressure fluids andconditions of use.
The AA6VM variable displacement motor is not suitable for usewith HFA. If HFB, HFC and HFD or environmentally-friendlypressure fluids are being used, the constraints regarding tech-nical data and seals mentioned in RA 90221 and RA 90223must be observed.If necessary, please contact us to discuss the type ofpressure fluid you intend to use.
Viscosity range
We recommend that a viscosity (at operating temperature) foroptimum efficiency and service life purposes of
νopt = optimum viscosity 80...170 SUS (16 to 36 mm2/s)
be chosen, taken the circulation temperature (closed circuit)and reservoir temperature (open circuit) into account.
Limits of viscosity range
The following values apply in extreme cases:
Sizes 28 to 200:
νmin = 42 SUS (5 mm2/s)short-term (t < 3 min) at max. permitted temperature oftmax = +240°F (+115°C).
νmax = 7400 SUS (1600mm2/s)short-term (t < 3 min) on cold start (p < 435 psi / 30 bar,n ≤ 1000 rpm, tmin = -40°F / -40°C).
Sizes 250 to 1000:
νmin = 60 SUS (10 mm2/s)short-term (t < 3 min) at max. permitted leakage-oil temperatureof tmax = +195°F (+90°C).
νmax = 4600 SUS (1000 mm2/s)short-term (t < 3 min) on cold start (p < 435 psi / 30 bar,n ≤ 1000 rpm, tmin = -13°F / -25°C).
Note that the maximum pressure fluid temperature must not beexceeded locally either (e.g. during storage).
Special measures are necessary at temperatures between-13°F and -40°F (-25°C and -40°C). Please contact us.
See RE 90300-03-B for detailed information about use at lowtemperatures.
Selection chart
Details regarding the choice of pressure fluid
The correct choice of pressure fluid requires knowledge of theoperating temperature in relation to the ambient temperature: ina closed circuit the circulation temperature, in an open circuitthe reservoir temperature.
The pressure fluid should be chosen so that the viscosity in theoperating temperature range is within the optimum area (νopt) -the shaded area of the selection chart. We recommend that thehigher viscosity class be selected in each case.
Example: At an operating temperature of 140°F (60°C), theviscosity classes VG 46 and VG 68 are within the optimumviscosity area (νopt., shaded field). In this case we would recom-mendVG 68.
Please note: The leakage-oil temperature, which is affected bypressure and rotational speed, is always higher than the circu-lation temperature or reservoir temperature. At no point in thesystem must the temperature be higher than 240°F (115°C) forsizes 28 to 200 or 195°F (90°C) for sizes 250 to 1000.
If this cannot be achieved due to unusual operating parametersor high ambient temperatures, we recommend flushing of thecase via port U or the use of a flushing and boost pressurevalve (see page 55).

Case drain pressureThe service life of the sealing ring is affected by the speed ofthe motor and the case drain pressure. The permitted loadingwith intermittent case drain pressure depends on the rotationalspeed (see chart). Short-term (t < 5 s) pressure spikes of upto 90 psi (6 bar) absolute are permitted.The average permanent case drain pressure must not exceed45 psi (3 bar) absolute.The pressure in the case must be equal to or greater than theexternal pressure on the shaft seal.The pure mechanical resistance to case pressure is approxi-mately 290 psi (20 bar).
Sizes 28 to 200
Technical DataFiltering
The finer the filtering, the cleaner the fluid and the greater theservice life of the axial piston unit.
To ensure proper function of the axial piston unit, the pressurefluid must have a cleanliness level of at least
20/18/15 according to ISO 4406.
At very high pressure fluid temperatures (195°F to max. 240°F/ 90°C to max. 115°C, not permitted for sizes 250 to 1000), acleanliness level of at least
19/17/14 according to ISO 4406 is required.
Please contact us if these cleanliness levels cannot beachieved.
Temperature range of shaft seal
The FKM shaft seal is suitable for case temperatures of-13°F to 240°F (-25°C to +115°C) for sizes 28 to 200 and-13°F to 195°F (-25°C to +90°C) for sizes 250 to 1000
Note:A NBR shaft seal is necessary at temperatures below -13°F /-25°C (permitted temperature range: -40°F to 195°F / -40°C to+90°C). Please contact us.

HD - Hydraulic Control, Pilot Pressure DependentThe pilot pressure dependent hydraulic system permitscontinuous control of the displacement according to thepilot pressure signal. The control is proportional to thepilot pressure present on port X.
Normal version:- start of control at Vg max (max. torque, min. speed)
- end of control at Vg min (min. torque, max. permitted speed)
Please note:
- Maximum permitted pilot pressure: 1450 psi (100 bar)
- The required control oil is taken from the high pressure.Therefore, a ∆p of at least 218 psi (15 bar) on the supplypressure is needed. If the ∆p on the supply pressure is< 218 psi (15 bar) (e.g. when idle), an auxiliary pressure of atleast 218 psi (15 bar) above the supply pressure must beapplied on port G via an external check valve (valid for size28...200, for size 250...1000 see page 11).
- Please state the required start of control in plain text whenplacing your order, 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 pressure in the case. A rise in pressure in the casecauses an increase in the start of control and a corres-ponding parallel movement of the performance curve(see page 5).
- Fluid will escape from port X at the rate of 0.08 gpm(0.3 l/min) due to internal leakage (operating pressure > pilotpressure). The actuation must be designed appropriately toensure correct control pressure.
HD1: pilot pressure rise ∆pS = 145 psi (10 bar)
A rise in pilot pressure of 145 psi (10 bar) on port X causes areduction in the displacement from Vg max to 0 cm3 (sizes 28 to200) or from Vg max to 0.2 Vg max (sizes 250 to 1000).

The pressure control overlays the HD function. If the loadmoment or a reduction in the swivel angle of the motor causesthe system pressure to rise, the motor will start to swivel to agreater angle when the pressure reaches the value set on thepressure control.
The increase in the displacement and the resulting reductionin pressure cause the controller deviation to decrease. Withthe increase in displacement the motor develops more torque,while the pressure remains constant.

HD.G: pressure control, remote
Sizes 250 to 1000
When the specified pressure is reached, the remote pressurecontrol regulates the motor continuously up to the maximumdisplacement Vg max. A pressure relief valve (not in the scope ofsupply) controls the internal discharge stop valve. The pressurerelief valve is separate from the motor and is connected to X3.If the pressure setpoint value is not reached, the valve is sub-jected to even pressure from both sides, in addition to thespring force, and remains closed. The pressure setpoint liesbetween 1160 and 5100 psi (80 and 350 bar). When this pres-sure is obtained on the separate pressure relief valve, the pres-sure relief valve opens and the pressure on the reservoir sideof the spring reduces. The internal control valve switches andthe motor swivels to maximum displacement Vg max.
The default value for the differential pressure on the controlvalve is 365 psi (25 bar). We recommend the following exter-nal pressure relief valve:

Please state the required start of control in plain text whenplacing your order, e.g.: start of control at 4350 psi (300 bar)
Sizes 28 to 200
In the case of automatic high-pressure dependent control, thedisplacement is set automatically according to the operatingpressure.
The control unit measures the internal operating pressure atA or B (no control line required) and, when the pressurereaches the setpoint value of Vg min set on the controller,swivels with increasing operating pressure to Vg max.
Normal version 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 permitted with startof control at Vg min (default with HA).
- The required control oil is taken from the high pressure, so a∆p of at least 218 psi (15 bar) on the supply pressure isneeded. If the ∆p on the supply pressure is < 218 psi(15 bar) (when idle), an auxiliary pressure of at least 218 psi(15 bar) above the supply pressure must be applied on portG via an external check valve (valid for size 28...200, for size250...1000 see page 11).
- The start of control and the HA characteristic are influencedby the pressure in the case. A rise in pressure in the casecauses an increase in the start of control and a corres-ponding parallel movement of the performance curve. Onlywith HA1, HA2, HA.T (sizes 250 to 1000) and HA1T (sizes28 to 200), see page 5.
- Fluid will escape from port X at the rate of 0.08 gpm(0.3 l/min) due to internal leakage (operating pressure > pilotpressure). The actuation must be designed appropriately toensure correct control pressure.Only with HA.T control.

For each 14.5 psi (1 bar) of pilot pressure, the start of controlis reduced by 247 psi (17 bar) for sizes 28 to 200 or 116 psi(8 bar) for sizes 250 to 1000.
Examples (sizes 28 to 200):
Start of control setting 4350 psi (300 bar) 4350 psi (300 bar)
Pilot pressure on port X 0 psi (0 bar) 145 psi (10 bar)
gives start of control at 4350 psi (300 bar) 1885 psi (130 bar)
If the override is only intended to set the max. displacement(motor swivels to Vg max), a maximum pilot pressure of 1450 psi(100 bar) is permitted.

HA - Automatic Control, High-Pressure Dependent (override)
HA.R1, R2: Electrical override of pressuresetpoint using electrical traveldirection valve
With the HA control, high-pressure dependent control can beoverridden by an electrical signal on solenoid b. In the case ofan override, the variable displacement motor swivels to themaximum swivel angle.
The travel direction valve ensures that the preselected pressureoutlet of the hydraulic motor always controls the swivel angle,even if the high pressure side changes (e.g. during a descent).This therefore prevents an undesirable swiveling of the variabledisplacement motor to a greater displacement.
Depending on the direction of rotation (direction of travel), thetravel direction valve (see page 21) can be actuated throughthe compression spring or solenoid a.

The AA6VM (A6VM) variable displacement motor with speed-dependent hydraulic control is best used for hydrostatic trans-missions in combination with the AA4VG variable displacementpump with DA control.
The pilot pressure derived from the driving speed of theAA4VG variable displacement pump, together with the operat-ing pressure, regulate the swivel angle of the hydraulic motor.
Increasing driving speed, i.e. rising pilot pressure, causes themotor to swivel to a lower displacement (lower torque, higherspeed), depending on the operating pressure.
If the operating pressure rises above the value set on thecontroller, the motor swivels to a higher displacement (highertorque, lower speed).
The design of a drive with DA control must be carried out usingthe technical data relating to the AA4VG variable displacementpump with DA control.
Detailed Information can be obtained from our sales departmentsand on the Internet at www.boschrexroth.com/da-control.
Please note:
- The start of control and the DA characteristic are influencedby the pressure in the case. A rise in pressure in the casecauses a drop in the start of control and a correspondingparallel movement of the performance curve (see page 5).

Depending on the direction of rotation (direction of travel), thetravel direction valve can be actuated through the compressionspring or solenoid a.
By connecting an electrical current to solenoid b, the controllercan be overridden and the motor adjusted to max.displacement (high torque, low speed) (so called “electricalVg max switch”).

DA - Hydraulic Control, Speed DependentElectrical travel direction valve (for DA, HA.R)The travel direction valve of the motor is switched using the4/3 directional-control valve on the control unit of the drivingpump. Usually, this provides trouble-free drivability of the drivenmachine.
However, with unfavorable operating parameters this can leadto undesired conditions (jerky, uncontrolled braking whenswitching the drive lever into neutral). The reason is that thetravel direction valve of the motor operates as soon as thepump is in the neutral position, causing the motor controller todetect a braking pressure, which is then used to control theswivel angle.
To prevent this, the existing switching position on the traveldirection valve must be retained while the pump is being putinto the neutral position, i.e. an energized valve must remainenergized. This can be done using the circuit shown below.
The motor should swivel more slowly than the pump.We therefore recommend that actuation be delayed byapproximately 0.8s. This prevents too long a delay whenreversing lightweight units.

Flushing and Boost Pressure ValveThe flushing and boost pressure valve is used to remove heatfrom the closed circuit and to ensure that a minimum chargepressure is present (opening pressure 230 psi/16 bar, fixed;note when setting primary valve). A side effect is flushing of thecase.
Warm pressure fluid is removed from the relevant low pressureside into the motor case. This is then fed into the reservoir,together with the leakage fluid. The pressure fluid drawn out ofthe closed circuit in this way has to be replaced by cooled oilthat is pumped in by the charge pump.
In the open circuit, the flushing and boost pressure valve isused solely to flush the case from the return line.
The valve is fitted to the variable displacement motor (or inte-grated into the servo unit, depending on the type of control andthe size).
Orifices can be used to adjust the flow as required.

Counterbalance Valve BVD (sizes 55 to 160)
Function
Driving/winch counterbalance valves prevent the motor speeding up out of control during descents/load reduction andconsequently cavitation of axial piston motors operating in an open circuit. Cavitation occurs in axial piston motors as soon as thespeed from the drive element on the outside exceeds the speed governed by the incoming flow volume.
Please note
– BVD counterbalance valve must be specified explicitly in the order. We recommend ordering the counterbalance valve and themotor as a set. Ordering example: AA6VM80HA1T/63W–VSC380A + BVD20F27S/41B–V03K16D0400S12
– For safety reasons, winch drive 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 contained in RE 95522

Fastening the counterbalance valve
When delivered, the counterbalance valve is fastened to the motorby 2 tacking bolts. Do not remove the tacking bolts when attach-ing the working lines. If the counterbalance valve and motor aredelivered separately, the counterbalance valve must first be fas-tened to the motor port plate using the tacking bolts provided. Inboth cases, the final fastening of the counterbalance valve to themotor is done using the threaded connection of the working lines,e.g. using SAE flanges. A total of 6 bolts with thread lengthsB1+B2+B3 and 2 bolts with thread lengths B3+B4 will be re-quired.
When tightening the bolts, it is vital that the sequence (1 to 8) asshown in the diagram is adhered to and carried out in two phases.
In the first phase the bolts should be tightened to 50% of theirtightening torque before being tightened to maximum tighteningtorque in a second phase (see table below).

The (A)A6VM...D and (A)A6VM...F (“prepared for speed measure-ment”) versions have teeth on the drive shaft.The rotating, toothed shaft generates a signal in proportion to thespeed. The signal is picked up by a sensor and forwarded forevaluation.
The sensor is screwed into (inductive speed sensor ID) or flangedonto (Hall effect speed sensor HDD) the upper leakage-oil port T1
(sizes 28 to 200). The spacerring (sizes 28 to 107) or thread re-ducing adapter (sizes 140 to 200) required for the inductivespeed sensor is supplied with the sensor. For the sizes 55, 80,107, 160 and 200 the port T is equipped with an adapter piece(M18x1.5) for the installation of the inductive speed sensor ID.
We recommended ordering the speed sensor and motor as a set.
Suitable sensors:
– Inductive speed sensor ID (see RE 95130)version “D”
– Hall-effect speed sensor HDD (see RE 95135)version “F”
On units employing speed measurement, port T2 must be usedto drain the leakage-oil (sizes 28 to 200).

Installation below the reservoir
Motor below minimum oil level in reservoir (standard)
– Fill axial piston motor before startup via the highestleakage-oil port
– Run the motor at low speed until the system is bledcompletely (bleed through service line port A, B if tubing islong)
– Minimum immersion depth of leakage line in reservoir:7.87 in/200 mm (relative to the min. oil level in the reservoir)
– Additional measures required for installation position 2(shaft facing up)
With installation position 2, make sure that the motor case iscompletely full before starting up. In this installation positionthe system must be bled via U. An air cushion in the vicinityof the bearing will damage the axial piston unit.
– Bleed the AA6VM variable displacement motor in a closedcircuit:- via port G- no bleeding required if flushing valve fitted
Installation above the reservoir
Motor above minimum oil level in reservoir
– Proceed in same way as below the reservoir installation
– Additional measures for installation positions 1 and 2
If stopped for an extended period, fluid may drain out of thecase chamber through the working lines (air enters throughthe shaft seal). The bearings will therefore not be properlylubricated when the motor is started up again. Fill the axialpiston unit before restarting via the highest leakage-oil port.In installation position 2 the system must be bled via U.
– Additional measures required for installation position 2(shaft facing up)
In this installation position the bearings will not be properlylubricated, even if there is still some fluid in the case chamber.Putting a check valve (opening pressure 7.25 psi/0.5 bar) inthe leakage line can prevent the system emptying through theline.
Installation and Startup InstructionsGeneral
The motor case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). Themotor must be started up at low speed and no load until the system has been bled completely.
If stopped for an extended period, fluid may drain out of the case through the working lines. When restarting, make sure that thecase contains sufficient fluid.
The leakage fluid inside the case chamber must be drained off to the reservoir through the highest leakage-oil port.
The motor is designed to operate in any position.
