Hydraulic fluidBefore starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and applica-tion conditions.
The variable motor A6VM is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally acceptable hydraulic flu-ids 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 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 = 5 mm2/s,short-term (t < 3 min) at max. perm. temperature of tmax = +115°C.
νmax = 1600 mm2/s,short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -40°C)Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes.
Sizes 250 to 1000:
νmin = 10 mm2/s,short-term (t < 3 min) at max. perm. temperature of tmax = +90°C.
νmax = 1000 mm2/s,short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, tmin = -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 115°C must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pres-sure and speed - up to 12 K higher than the average case drain temperature.
Special measures are necessary in the temperature range from -40°C and -25°C (cold start phase), 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 tem-perature of 60°C is set in the control. 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 control temperature or tank temperature. At no point in the system may the temperature be higher than 115°C for sizes 28 to 200 or 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
6/76 Bosch Rexroth AG A6VM RE 91604/01.07
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 hy-draulic fluid must have a claenliness level of at least
20/18/15 according to ISO 4406.
At very high hydraulic fluid temperatures (90°C to max. 115°C) at least cleanliness level
19/17/14 according to ISO 4406 is required.
If the above classes cannot be observed, please contact us.

Shaft seal ring
Permissible 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 tem-perature 3 bar absolute not be exceeded (max. permissible case drain pressure 6 bar absolute at reduced speed, see diagram). Short term (t < 0.1 s) pressure spikes of up to 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 exter-nal pressure on the shaft seal ring.

Please contact us.3) max. permissible axial force when at a standstill or when axial piston unit operating in depressurized condition.4) please contact us.
When considering the permissible axial force, the force-transfer direction must be taken into account.
– Fax max = increase in service life of bearings
+ Fax max = reduction in the service life of bearings (avoid)
Effect of radial force F on the service life of bearings
By selecting a suitable force-transfer direction of Fq, the stress on the bearings caused by the internal transmission forces can be reduced, thus achieving the optimum service life of the bearings. Recommended position of mating gear is dependent on direction of rotation. Examples:
Toothed gear drive V-belt drive

HD - Hydraulic control, pilot-pressure relatedThe pilot-pressure related hydraulic control permits infinite con-trol 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: 100 bar
– For reliable control, an operating pressure of at least 30 bar is necessary in A (B). If a control operation is performed at an operating pressure < 30 bar, an auxiliary pressure of at least 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 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 and thus a parallel displacement of the characteristic (see page 6).
– Fluid escapes from port X at the rate of max. 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 = 10 barAn increase in pilot pressure of 10 bar on port X causes a reduc-tion in the displacement from V g 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 in the control unit is not a security device.
The control spool and/or the positioning piston can be blocked in an undefined position by internal contamination – e.g. impure hydraulic fluid, abrasion or residual contamina-tion from system components. As a result, the variable motor can no longer provide the speed and torque specified by the operator.
– Install an appropriate emergency-off function to ensure that the driven consumer can be brought to a safe position (e.g. immediate stop).
– Maintain the specified cleanliness level 20/18/15 (< 90°C) or 19/17/14 (> 90°C) in accordance with ISO 4406.
HD - Hydraulic control, pilot-pressure relatedHD.D Pressure control, directThe pressure control overlays the HD function. If the load in-creases, 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 (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 pres-sure cut-off valve is 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 mo-tor displacement is adjusted automatically depending on the operating 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).
– For reliable control, an operating pressure of at least 30 bar is necessary in A (B). If a control operation is performed at an operating pressure < 30 bar, an auxiliary pressure of at least 30 bar is to be applied at port G via an external check valve. Lower pressures may be adequate in individual cases.
– 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 and thus a paral-lel 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), see page 5.
The following only applies to sizes 250 to 1000:
– Fluid escape from port X at the rate of 0.3 l/min due to inter-nal 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.

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 24) can be actuated through the pressure spring or switching solenoid a.

DA - Hydraulic control, speed relatedThe A6VM variable motor with speed-related hydraulic control is best used for hydrostatic drives in combination with the A4VG variable pump with DA control.
The pilot pressure derived from the drive speed of the A4VG 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 A4VG variable pump with DA control.
Detailed information can be obtained from our sales departments 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 and thus a parallel dis-placement of the characteristic (see page 6).

Application in travel drives in closed controls. 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 (A4VG, A10VG) 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 fol-lowing electric control.
With this control, when the pump (A4VG, A10VG) 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 control and to ensure that a minimum boost pressure is present (opening pressure 16 bar, fixed; note when setting primary valve). A side effect is flushing of the case.
Warm hydraulic fluid is directed from the respective low pres-sure side into the motor case. This is then fed into the tank, together with the case drain. The hydraulic fluid drawn out of the closed control in this way must be replaced by cooled hydraulic fluid that is supplied by the boost pump.
In an open control system, the flush and boost pressure valve is used solely to flush the case from the return line.
The valve is fitted 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 = 25 bar)

For sizes 28 to 200, orifices for flushing volumes of 3.5 - 10 l/min can be supplied. In the case of non-standard flushing volumes, please specify the desired flushing volume when ordering. The flushing volume without orifice is approx. 12 to 14 l at low pressure ΔpLP = 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 controls. 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: A6VM80HA1T/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 contained in RE 95522
Driving counterbalance valve BVD...F Winch counterbalance valve BVD...WExample of application
– Travel drive on wheeled excavators
Typical applications
– Winch gears 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 counterbal-ance valve and motor are delivered separately, the counter-balance 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 A6VM...D and A6VM...F ("prepared for speed measure-ment", 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 28-200)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.
Version "F" (NG 55-250)Suitable for mounting the HDD Hall-effect speed sensor (see RE 95135). With sizes 28 to 200, the HDD sensor is flanged onto the upper case drain port T1; with size 250, 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-re-sistant flange cover.
We recommend ordering the A6VM variable motor complete 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. fl uid level of the tank
– Note: Installation position 8 (shaft up)
In this installation position, if the case interior is only par-tially drained, lubrication of the bearings will no longer be adequate. A check valve (opening pressure 0.5 bar) in the case drain line can prevent the system emptying through the case drain line.

General notes– The A6VM motor is designed to be used in open and closed controls.
– Project planning, assembly, and commissioning of the motor require the involvement of qualified personnel.
– The service line ports and function ports are only designed to accommodate hydraulic lines.
– During and shortly after operation, there is a risk of burns on the motor and especially on the solenoids. Take suitable safety precautions, e.g. wear protective clothing
– There may be shifts in the characteristic depending on the operating state of the motor (operating pressure, fluid temperature).
– Tightening torques:- The tightening torques specified in this data sheet are maximum values and must not be exceeded (maximum values for screw thread). Manufacturer's instruction for the max. permissible tightening torques of the used fittings must be observed!- For DIN 13 fixing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.
– The data and information contained herein must be adhered to.
