6 Specifications Bearing life General information Bearing life can be calculated for that part of the load/ life curve (shown below) that is designated Bearing fatigue. Fatigue of rotating parts and Wear caused by fluid contamination, etc., should also be taken into consi-deration when estimating the service life of a motor/pump in a specific application. In reality, bearing life can vary considerably due to the quality of the hydraulic system (fluid condition, cleanliness, etc.) Bearing life calculations are mainly used when comparing different motor frame sizes. Bearing life, designated B 10 (or L 10 ), depends of system, opera-ting speed, external shaft loads, fluid viscosity in the motor case, and fluid contamination level. The B 10 value means that 90% of the bearings survive at least the number of hours calculated. Statistically, 50% of the bearings will survive at least five times the B 10 life. Life expectancy (logarithmic scale) Wear Bearing fatigue Fatigue of rotating parts Series V12, V14 and T12 Bearing life calculation n application is usually governed by a certain duty or work cycle where, speed and displacement vary with time during the cycle. Bearing life is also dependent on external shaft loads, case fluid viscosity and fluid contamination. Required information When requesting a bearing life calculation from Parker Hannifin, the following information (where applicable) should be provided: - short presentation of the application - Motor size and version - Duty cycle ( and speed versus time at specified displacements) - Low - Case fluid viscosity - Life probability (B 10, B 20, etc.) - Direction of rotation (L or R) - xial load - Fixed or rotating radial load - Distance between flange and radial load - ngle of attack (α) as defined below.

10 Controls Series V12 Controls (general information) The following six V12 controls described below satisfy most application requirements: C and H (Pressure compensator) EO and HO (Two-position controls) EP and HP (Proportional controls). ll controls utilize a setting piston that connects to the valve segment (refer to the picture on page 8). The built-in four-way servo valve acts on the setting piston and determines the displacement which can vary between 35 (max) and 6.5 (min). C compensator The C compensator is used in off-road vehicle hydrostatic transmissions; it automatically adjusts motor displacement to the output torque requirement (up to max available system ). Normally, the motor stays in the minimum displacement position. When there is a demand for additional torque, i.e. when the vehicle enters an upgrade, the displacement increases (providing more torque) while the motor shaft speed decreases proportionally. The threshold ( ps ; refer to the C diagram) where displacement starts to increase, is adjustable between 150 and 400 bar. To reach max displacement, an additional modulating (Dp) above the threshold (ps) is required. To satisfy specific hydraulic circuit requirements, a modulating, Dp, of 15, 25 or 50 bar can be selected. The C compensator is available in two versions: CI 01 I - Internal pilot CE 01 I - External pilot ; port X5 can, for (optional) example, be connected to the forward drive line of a vehicle transmission to prevent motor displacement increase when the vehicle is going downhill.

Servo supply (after orifice) Servo supply (before orifice) External pilot Setting piston (decreasing displ.) M14x1.5 (ISO and cartridge versions) 9 / 16 "-18 O-ring boss (SE version). Servo supply is usually obtained from the main high port through the built-in shuttle valve. When using external servo supply, the servo should be at least 30 bar. The response time (i.e. from max to min displacement) is determined by orifices in the servo valve supply and return lines. NOTE: The modulating /current, p/ I values are valid for motors that are not displacement limited. Displacement (setting piston position) C diagram.

11 Controls H compensator The H compensator is similar to the C (page 10) but incorporates an hydraulic override device. It is utilized in hydrostatic transmissions where a high degree of manoeuvrability at low vehicle speeds is desirable. When the override is pressurized, the servo piston moves to the max displacement position irrespective of system, provided the servo supply is at least 30 bar. The H compensator is available in two versions: HI 01 I - Same as the CI except for the override; internal pilot. HE 01 I - External pilot (port X5; compare (optional) CE, page 10).

12 Controls D compensator with brake defeat The D control is similar to the CI (internal pilot supply; page 10) but incorporates a solenoid controlled override function. In addition, the D includes a brake defeat valve which prevents motor displacement increase in the braking mode. The override consists of a piston built into the D end cover and an external electrohydraulic solenoid valve. When the solenoid is energized, system is directed to the piston which in turn pushes on the spool of the servo control valve. This causes the motor to lock in the max displacement position, irrespective of system (min 30 bar). Solenoids are available in 12 VDC (designated L) and 24 VDC (design. H); the required current is 2 and 1 respectively. The brake defeat valve is also part of the D end cover and consists of a two-position, three-way spool. The two ports, x9 and x10 (below) should be connected to the corresponding ports of the displacement control of the variable displacement pump. The brake defeat function prevents the motor outlet port to influence the compensator. If, for example, port is being pressurized when driving forward, in port B during braking will not cause the motor to increase its displacement. Likewise, when driving in reverse (port B pressurized), any braking in port will not influence the control; refer to the schematic.

13 Controls EO two-position control The EO is a two-position control, where max and min displacements are governed by a DC solenoid attached to the control cover (refer to the installation drawing on page 30). The EO control is utilized in transmissions where only two operating modes are required: Low speed/high torque or high speed/low torque. The servo piston, normally in the max displacement position, shifts to the min displacement position when the solenoid is activated. Intermediate displacements cannot be obtained with this control. Servo is supplied internally (through the shuttle valve from one of the main high ports) or externally (port X4). The solenoid is either 12 or 24 VDC, requiring 1200 and 600 m respectively. n electrical connector is included (DIN 43650/IP54). The EO two-position control is available in four versions: EOH 01 I - Internal servo supply, 24 VDC EOL 01 I - Internal servo supply, 12 VDC EOH 01 E - External servo supply, 24 VDC (optional) EOL 01 E - External servo supply, 12 VDC (optional) Series V12 Displacement (setting piston position) I s Threshold current EO diagram.

14 Controls Series V12 EP proportional control The EP electrohydraulic proportional control is used in hydrostatic transmissions requiring a continuously variable shaft speed. The position of the setting piston is governed by a DC solenoid attached to the control cover. When the solenoid current increases above the threshold current, the servo piston starts to move from the max towards the min displacement position. The displacement vs. solenoid current is shown in the diagram to the right. Please note, that the shaft speed vs. current is non-linear; refer to the diagram below. Solenoids are available in 12 and 24 VDC versions, requiring a max current of approx and 550 m respectively. n electrical connector is included (DIN43650/IP54). The threshold current (I s ) is factory set 400 m at 12 VDC/200 m at 24 VDC) but is adjustable (12 VDC: m; 24 VDC: m). When utilizing the full displacement range, the required modulating current ( I) is 600 and 300 m respectively. In order to minimize hysteresis, a pulse-width modulated control signal of 70 to 90 Hz should be utilized. See also Controls, Note on page 10. NOTE: The modulating current ( I) is not adjustable. The EP control is available in four versions: EP H 01 I - Internal servo supply, 24 VDC EP L 01 I - Internal servo supply, 12 VDC EP H 01 E - External servo supply, 24 VDC (optional) EP L 01 E - External servo supply, 12 VDC (optional) Gauge/pilot ports (EP control): X1 Setting piston (decreasing displ.)

15 Controls HO two-position control The two-position HO control is similar to the EO (page 13) but the pilot signal is hydraulic. The position of the setting piston is governed by the built-in servo valve (same on all compensators and controls). When the applied pilot (port X5) exceeds the pre-set threshold, the setting piston moves from the max to the min displacement position. The threshold is factory set at 10 bar but can be adjusted between 5 and 25 bar. The HO two-position control is available in two versions: HO S 01 I - Internal servo supply HO S 01 E - External servo supply (port X4) (optional) Gauge/pilot ports (HO control): X1 Setting piston (max-to-min) X2 Servo supply (after orifice) X4 Servo supply (before orifice) X5 External pilot (max 100 bar) X6 Setting piston (min-to-max) Port sizes: M14x1.5 (ISO and cartridge versions) 9 / 16 "-18 O-ring boss (SE version).

16 Controls HP proportional control Like the EP control described on page 14, the HP proportional control offers continuously variable displacement, but the pilot signal is hydraulic. Normally, the setting piston stays in the max displacement position. When a sufficiently high pilot (p s ) is applied to port X5, the setting piston starts to move towards the min displacement position. s can be seen in the diagram to the right, the displacement changes in proportion to the applied modulating. In contrast, shaft speed vs. pilot is non-linear; refer to the diagram below. The following modulating s ( p) can be selected: 15 or 25 bar. The threshold (p s ) is factory set at 10 bar but is adjustable between 5 and 25 bar. See also Controls, Note on page 10. Two versions of the HP control are available: HPS 01 I - Internal servo supply HPS 01 E - External servo supply (port X5) (optional) Gauge/pilot ports (HP control): X1 Setting piston (decreasing displ.)

17 Valve and sensor options Flushing valve s an option, L, the V12 is available with a flushing (or shuttle) valve that supplies the motor with a cooling flow through the case. Cooling the motor may be required when operating at high speeds and/or power levels. The flushing valve consists of a three-position, threeway spool valve built into a special end cap. It connects the low side of the main circuit to a nozzle (optional size) that empties fluid into the motor case. In a closed circuit transmission, the flushing valve removes part of the fluid in the main loop. The removed fluid is continuously being replaced by cool, filtered fluid from the low charge pump on the main pump. NOTE: The flushing valve ordering code is shown on page 23 ( L 01 ).

19 Valve and sensor options Series V12 Speed sensor speed sensor kit is available for the ISO, Cartridge and SE versions of series V12, V12-80-Cartridge excepted. The ferrostat differential (Hall-effect) sensor installs in a separate, threaded hole in the V12 bearing housing. The speed sensor is directed towards the V12 shaft flange and outputs a 2 phase shifted square wave signal within a frequency range of 0 Hz to 15 khz. Number of pulses per shaft rev is 36 which, at 5 Hz, corresponds to approx. 8 rpm. When a Speed sensor is needed (refer to the ordering codes on pages 20 to 22), the housing is machined with the threaded hole; the speed sensor kit have to be ordered on a separate order line. NOTE: - The motor bearing housing must be prepared for the speed pick-up; refer to the V12 ordering codes on pg. 20, 21 and 22 (Code P). - dditional information is provided in our publication HY /UK Speed sensor for series F11/F12 and V12/T12/V14 ; available from Parker Hannifin. - The speed sensor is also shown in the illustrations on pg. 24 and 28.

34 Controls Series V14 Controls - general information The following V14 controls satisfy most application requirements: C, D and H (automatic compensators) EO and HO (two-position controls) EP and HP (proportional controls) HPC/EPC (HP/EP control with cut off, see page 45) ll controls utilize a servo piston that connects to the valve segment (refer to the illustration on page 32). The built-in four-way servo valve determines the position of the servo piston and, in turn, the displacement. C compensator E The displacement angle (between output shaft and cylinder barrel) ranges from 35 (max) to 6.5 (min). Servo supply is obtained from the pressurized, main port through the corresponding, built-in shuttle valve. The response time (i.e. from max-to-min or from min-tomax displacement) is determined by restrictor nozzles in the servo valve supply and return lines; refer to the schematics.

35 Controls Series V14 C compensator function Refer to the illustration below (left): When in port (or B) increases, the servo valve spool is pushed to the right, directing flow to the right hand setting chamber - the setting piston moves to the left; displacement and output torque increases. t the same time, the shaft speed decreases correspondingly (at a constant pump flow to the motor). Refer to the illustration below (right): When in port (or B) decreases, the servo valve spool moves to the left, directing flow to the left hand setting chamber - the setting piston moves to the right; displacement and output torque decreases. t the same time, the shaft speed increases correspondingly (at a constant pump flow to the motor).

36 Controls Series V14 C compensator function (cont d) The C compensator is used in off-road vehicle hydrostatic propel transmissions. The compensator automatically adjusts motor displacement between available max and min to the output torque requirement (up to max available system ). Normally, the motor stays in the minimum displacement position. When there is a demand for additional torque, e.g. when the vehicle enters an upgrade, the displacement increases (providing more torque) while the motor shaft speed decreases proportionally. The threshold, where displacement starts to increase ( p s ; refer to the C diagram), is adjustable between 100 and 400 bar. To reach max displacement, an additional modulating ( p) above the threshold is required. To satisfy specific hydraulic circuit requirements, a modulating of 15, 25, 50 or 80 bar can be selected. The compensator is supplied with a small filter installed in the C control cover (between ports X4 and X5); refer to the schematic below right.

37 Controls Series V14 D compensator The D control is similar to the C (shown on previous pages) but incorporates a solenoid controlled override function and a brake defeat valve. Override - The override consists of a piston built into a special end cover and an external solenoid. - When the solenoid is energized, system is directed to the piston which in turn pushes on the servo valve spool. This causes the motor to lock in the max displacement position, irrespective of system (min 30 bar). - Solenoids are available in 12 VDC (designated L) and 24 VDC (design. H); the required current is 2 and 1 respectively. Brake defeat valve - The brake defeat function, which is also built into the special end cover, consist of a two-position, three-way valve. Ports X9 and X10 (refer to the schematic) are connected to the corresponding ports of the pump displacement control. - The function prevents any in the motor return port to influence the compensator. Say, e.g., that motor port is pressurized to move the vehicle forward. Thus, back in return port B, which develops in the braking mode, will not cause the compensator to move towards the max displacement position and vehicle braking will be smooth. - Likewise, when port B is pressurized when the vehicle moves backward, braking presssure in port will not influence the compensator.

38 Controls H compensator The H compensator is similar to the D (shown on previous page) but incorporates only an hydraulic override device. It is utilized in hydrostatic transmissions where a high degree of manoeuvrability at low vehicle speeds is desirable.

39 Controls EO, EP, HO and HP controls (general information) Basically, these controls function in a similar way. t increasing solenoid current (EP) or increasing pilot (HP) the control moves towards the min displacement position. t decreasing current or pilot, the control retracts towards max displacement. Series V14 In comparison with EP and HP, the EO and HO controls have no modulating spring; this means that only min and max displacements can be obtained with these controls. and min displacements can be limited by a screw with spacer bushing as shown below E Cross section of the EP control module. 1.

40 Controls EP control function (solenoid current increasing) NOTE: Valid also for the HP at increasing pilot. Refer to the illustration below left: t an increasing current (above the threshold value), the solenoid spool pushes left on the servo valve spool, and flow is directed to the left hand setting chamber - the setting piston moves to the right and the displacement decreases. This means, that the shaft speed in-creases while the output torque decreases correspondingly (at a constant pump flow and system ). Series V14 HP control function (decreasing pilot ) NOTE: Valid also for the EP at decreasing current. Refer to the illustration below right: When the pilot decreases, the servo valve spool moves to the right and flow is directed to the right hand setting chamber - the setting piston moves to the left and the displacement increases.

41 Controls EO electric two-position control - The EO is a two-position control where the position of the setting piston is governed by a DC solenoid (acting on the servo spool) which is attached to the control module (refer to the illustration on page 40). - The EO is utilized in transmissions where only two operating modes are required - low speed/high torque and high speed/low torque. - The setting piston, normally in the max displacement position, shifts to min displacement as soon as the solenoid is activated. - Intermediate displacements cannot be obtained with this control. Displacement (setting piston position) Series V14 - Servo is supplied internally (through a check valve from the utilized high port); refer to the schematic below. - The solenoid is either 12 or 24 VDC, requiring 1200 m and 600 m respectively. - The male connector (type Junior Timer ) is permanently installed on the solenoid. The corresponding female connector is not included. Note: The female connector is available as spare part P-N The threshold current of the 12 VDC solenoid is factory set at 400 m; it is adjustable between 200 and 500 m.

42 Controls EP electrohydraulic proportional control - The EP electrohydraulic proportional control is used in hydrostatic transmissions requiring a continuously variable shaft speed. The position of the setting piston is governed by a DC solenoid (acting on the servo valve spool), attached to the control module (refer to the illustration on page 40). - When the solenoid current increases above the threshold value, the setting piston starts to move from max towards min displacement. The displacement vs. solenoid current is shown in the diagram below. NOTE: The shaft speed is not proportional to the solenoid current; refer to the bottom diagram. Displacement (setting piston position) threshold current threshold current Series V14 - The solenoid is either 12 or 24 VDC, requiring 1200 and 600 m respectively. - The male connector (type Junior Timer ) is permanently installed on the solenoid. The corresponding female connector is not included. Note: The female connector is available as spare part P-N The threshold current of the 12 VDC solenoid is factory set at 400 m; it is adjustable between 200 and 500 m. The 24 VDC solenoid is factory set at 200 m and is adjustable between 100 and 250 m. - When utilizing the full displacement range, the required modulating current ( I) is 600 m (12V solenoid) and 300 m (24 V solenoid) for V14-110, 345 m (24 V solenoid) for V respectively. In order to minimize hysteresis, a pulse-width modulated control signal of 50 to 60 Hz should be provided. NOTE: The modulating current ( I) is not adjustable.

43 Controls Series V14 HO hydraulic two-position control - The two-position HO control is similar to the EO (page 41) but the control signal is hydraulic. The position of the setting piston is governed by the built-in servo valve spool (same as on all controls). - When the applied pilot (port X5) exceeds the pre-set threshold value, the setting piston moves from the max to the min displacement position. - Positions between max and min cannot be obtained with this control. - The threshold is factory set at 10 bar but is adjustable between 5 and 25 bar.

44 Controls HP hydraulic proportional control - Like the EP described on page 40, the HP proportional control offers continuously variable displacement, but the controlling signal is hydraulic. - Normally, the setting piston stays in the max displacement position. When a sufficiently high pilot (p s ) is applied to port X5, the setting piston starts to move towards the min displacement position. Displacement (setting piston position) Series V14 - s can be seen from the pilot /displacement diagram below, the displacement changes in proportion to the applied modulating. - In contrast, the shaft speed is not proportional to the pilot ; refer to the bottom left diagram. - To satisfy specific hydraulic circuit requirements, a modulating of 15 or 25 bar can be selected; the threshold (p s ) is set at 10 bar but is adjustable between 5 and 25 bar.

Cooling the motor may be required when operating at high speeds and/or power levels. The flushing valve consists of a three-position, threeway spool valve built into the connection module. It connects the low side of the main circuit to a nozzle (optional sizes below) that empties fluid into the motor case. In a closed circuit transmission, the flushing valve re-moves part of the fluid in the main loop. The removed fluid is continuously being replaced by cool, filtered fluid from the low charge pump on the main pump.

47 Valve and sensor options Pressure relief valves (option P) To protect the motor (and the main hydraulic circuit) from unwanted, high peaks, the V14 can be supplied with relief valve cartridges. The individual cartridge (with integrated check valve function) has a non-adjustable, factory-set opening, available in settings shown below. The cross section (below right) shows a situation, where the upper cartridge has opened because of high fluid. This, in turn, forces the opposite cartridge to open to the low area (this cartridge now acting as a check valve). s shown, a small part of the flow may go directly to the reservoir. PLESE NOTE: - The relief cartridges should not be used as main reliefs; in a motor application, they should only be relied on to limit short duration peaks (or the temperature of the fluid which circulates through the motor will rapidly reach damaging high levels). - The main relief is usually installed in the main pump or in the directional control valve, or is line mounted between pump and motor. vailable cartridges Ordering code B Pressure setting [bar] Cartridge valve Part number P P P P P P P V14_P_inst_schematic.eps (optional) Hydraulic schematic - V14 with cartridge valves.

48 Valve and sensor options Series V14 Shaft speed sensor (option P) speed sensor kit is available for the V14. The ferrostat differential (Hall-effect) sensor installs in a separate, threaded hole in the V14 bearing housing. The speed sensor is directed towards the V14 shaft flange and outputs a 2 phase shifted square wave signal within a frequency range of 0 Hz to 15 khz. Number of pulses per shaft rev is 36 which, at 5 Hz, corresponds to approx. 8 rpm.

49 Valve and sensor options Series V14 Setting piston position sensor (option L) The setting piston position sensor, also referred to as a Sub-iature In-Cylinder Transducer, combines the best features associated with LVDT s (Linear Variable Differential Transformer) and potentiometers into one rugged, contactless, highly reliable position sensor. The stationary part of the sensor, the sleeve, is provided with a flange that fits in a specially machined boring in the control module housing. The movable shaft of the sensor is attached to the feedback arm as shown in the illustration to the right. When the sensor is properly connected to the electronic module (packed separately with an installation sheet), the produced output signal is proportional to the position of the setting piston. In order to obtain the correct electrical max and min position settings, as determined by the utilized max and min displacements, the programming module (part of the electronic module, illustrated below right) must be adjusted; for further information please contact Parker Hannifin.
