Recommended installation position
Pump installation position is discretionary, however the recommended control position is on the top or
at the side with the top position preferred. If the pump is installed with the control at the bottom,
flushing flow must be provided through port M14 located on the EDC, FNR and NFPE control.
Vertical input shaft installation is acceptable. If input shaft is at the top, 1 bar case pressure must be
maintained during operation.
The housing must always be filled with hydraulic fluid.
Recommended mounting for a multiple pump stack is to arrange the highest power flow towards the
input source.
Consult Danfoss for nonconformance to these guidelines.

Bearing Life and External Radial Shaft Loads
All external shaft loads affect bearing life. The pumps are designed with bearings that can accept some
external radial loads. The external radial shaft load limits are a function of the load position and
orientation, and the operating conditions of the unit.
Danfoss recommends clamp-type couplings for applications with radial shaft loads. Contact your Danfoss
representative for an evaluation of unit bearing life if you have continuously applied external loads
exceeding 25 % of the maximum allowable radial load (Re) or the pump swash-plate is positioned on one
side of center all or most of the time.

External radial shaft loads impact lifetime. For lifetime calculations please contact your Danfoss
representative. In applications with external shaft loads, minimize the impact by positioning the load at
0° or 180° as shown below.
The maximum allowable radial shaft load (Re) is based on the maximum external moment (Me) and the
distance (L) from the mounting flange to the load. It may be determined using the following formula:
Thrust loads should be avoided. Contact your Danfoss representative in the event thrust loads are
anticipated.
H1P 115/130 Mounting Flange Loads
The Rated and Shock load moments apply for top or side orientation of control.
In most applications a general guideline is that the charge pump displacement should be at least 10% of
the total displacement of all components in the system. Unusual application conditions may require a
more detailed review of charge flow requirements. System features and conditions which may invalidate
the 10% guideline include (but are not limited to):
Continuous operation at low input speeds < 1500 min-1 (rpm)
•
High shock loading and/or long loop lines
•
High flushing flow requirements
•
Multiple low speed high torque motors
•
High input shaft speeds
•
Contact your Danfoss representative for application assistance if your application includes any of these
conditions.

The Electrical Displacement Control (EDC) consists of a pair of proportional solenoids on each side of a
three-position, four-way porting spool. The proportional solenoid applies a force input to the spool,
which ports hydraulic pressure to either side of a double acting servo piston.
Differential pressure across the servo piston rotates the swash-plate, changing the pump‘s displacement
from full displacement in one direction to full displacement in the opposite direction. A serviceable 125
μm screen is located in the supply line immediately before the control porting spool.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement.

Control Response
H1 controls are available with optional control passage orifices to assist in matching the rate of swashplate response to the application requirements. The time required for the pump output flow to change
from zero to full flow (acceleration) or full flow to zero (deceleration) is a net function of spool porting,
orifices, and charge pressure.
H1 pumps are limited in mechanical orifice combinations. Mechanical servo orifices are to be used only
for fail-safe return to neutral in a case of an electrical failure.
A swash-plate response times table is available for each frame size. Testing should be conducted to verify
the proper orifice selection for the desired response. Typical response times at the following conditions:
∆p = 250 bar [3626 psi]
Charge pressure = 20 bar [290 psi]

A Manual proportional Displacement Control (MDC) consists of a handle on top of a rotary input shaft.
The shaft provides an eccentric connection to a feedback link. This link is connected on its one end with a
porting spool. On its other end the link is connected the pumps swash-plate.
This design provides a travel feedback without spring. When turning the shaft the spool moves thus
providing hydraulic pressure to either side of a double acting servo piston of the pump.
Differential pressure across the servo piston rotates the swash plate, changing the pump’s displacement.
Simultaneously the swash-plate movement is fed back to the control spool providing proportionality
between shaft rotation on the control and swash-plate rotation.
The MDC changes the pump displacement between no flow and full flow into opposite directions. Under
some circumstances, such as contamination, the control spool could stick and cause the pump to stay at
some displacement.
A serviceable 125 μm screen is located in the supply line immediately before the control porting spool.
The MDC is sealed by means of a static O-ring between the actuation system and the control block. Its
shaft is sealed by means of a special O-ring which is applied for low friction. The special O-ring is
protected from dust, water and aggressive liquids or gases by means of a special lip seal.

Maximum allowable input torque20 N•m [177 lbf•in]
Caution
Volumetric efficiencies of the system will have impacts on the start and end input commands.
In difference to other controls the MDC provides a mechanical deadband. This is required to overcome
the tolerances in the mechanical actuation.
The MDC contains an internal end stop to prevent over travel. The restoring moment is appropriate for
turning the MDC input shaft back to neutral only. Any linkages or cables may prevent the MDC from
returning to neutral.
The MDC is designed for a maximum case pressure of 5 bar and a rated case pressure of 3 bar. If the case
pressure exceeds 5 bar there is a risk of an insufficient restoring moment. In addition a high case pressure
can cause the NSS to indicate that the control is not in neutral. High case pressure may cause excessive
wear.
Customers can apply their own handle design but they must care about a robust clamping connection
between their handle and the control shaft and avoid overload of the shaft.
Customers can connect two MDC’s on a tandem unit in such a way that the actuation force will be
transferred from the pilot control to the second control but the kinematic of the linkages must ensure
that either control shaft is protected from torque overload. To avoid an overload of the MDC, customers
must install any support to limit the setting range of the Bowden cable.
Caution
Using the internal spring force on the input shaft is not an appropriate way to return the customer
connection linkage to neutral.

Neutral Start Switch (NSS)
The Neutral Start Switch (NSS) contains an electrical switch that provides a signal of whether the control
is in neutral. The signal in neutral is Normally Closed (NC).
The 3-position FNR control options A9 (12 V) and B1 (24 V) uses an electric input signal to switch the
pump to a full stroke position. A serviceable 125 μm screen is located in the supply line immediately
before the control porting spool.

The Non Feedback Proportional Electric (NFPE) control is an electrical automotive control in which an
electrical input signal activates one of two proportional solenoids that port charge pressure to either side
of the pump servo cylinder. The NFPE control has no mechanical feedback mechanism.
A serviceable 170 μm screen is located in the supply line immediately before the control porting spool.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement.

The pump displacement is proportional to the solenoid signal current, but it also depends upon pump
input speed and system pressure. This characteristic also provides a power limiting function by reducing
the pump swash-plate angle as system pressure increases.
A typical response characteristic is shown in the accompanying graph below:

The H1 Automotive Control (AC) is an electric NFPE Control with an integrated microcontroller, installed
on the pump. The integrated microcontroller enhanced control performance with a flexible, configurable
control scheme for an entire single path propel transmission. It can be used in combination with fixed
and variable displacement hydraulic-motors. With the pre-installed application software and easily
changeable control parameters, it is possible to tailor the vehicle’s driving behavior to the individual
requirements of the customer.
The H1 Automotive Control is divided into 2 systems:
AC-1
•
AC-2
•
AC-2 is an extension of AC-1 that features an integrated pump swash plate angle sensor and software
enabled functions such as Swash Plate Control.
Mode types
The application software provides 3 different hydrostatic propel methods, defined as mode types, which
can be used individually.
Automotive Load dependent (torque controlled) driving behavior. Setpoint for the drive curve is
•
the engine rpm.
Non-Automotive Load independent (speed controlled) driving mode. Setpoint for the drive curve is
•
a Joystick or drive pedal signal, independent of the engine rpm. The best performance will achieved
with an AC-2 Swash Plate Angle Sensor.
Setpoint for the drive curve is the engine rpm. The setpoint can be reduced by the creep
potentiometer if a high engine rpm in combination with low vehicle speed is needed.
Basic functions
Four selectable system modes, selectable via switch.
•
Individual settings for forward and reverse driving direction (4 x 2 curves).
•
Independent pump and hydraulic-motor profiling and ramping for each mode.
•
Electric drive pedal connection
•
Electronic inching function without separate control valve
The Fan Drive Control (FDC) is a non-feedback control in which an electrical input signal activates the
proportional solenoid that ports charge pressure to either side of the pump servo cylinder. The single
proportional solenoid is used to control pump displacement in the forward or reverse direction.
The control spool is spring biased to produce maximum forward pump displacement in the absence of
an electrical input signal. Based on the spring bias spool default forward flow for a CW rotation pump is
out of port B while default forward flow for a CCW rotation pump is out of port A.
FDC control
FDC schematic
The pump should be configured with 0.8 mm control orifices to provide slowest response and maximize
system stability. Additionally, pressure limiter (PL) valves are used to limit maximum fan trim speed in
both (forward and reverse) directions.
H1 pumps with FDC will be delivered from factory with nominal pressure limiter setting of 150 bar [2175
psi]. The PL must be re-adjusted to ensure that the fan reaches the desired fan speed to satisfy the
cooling needs of the system. HPRV setting must be always at least 30 bar [435 psi] higher than PL setting.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement.
For more information necessary to properly size and configure a hydraulic fan drive system, see HydraulicFan Drive Design GuidelinesAB00000019.
Use in other systems could result in unintended movement of the machine or it’s elements. Loss of the
input signal to this control will cause the pump to produce maximum flow.
The FDC is for Fan Drive systems only!
Due to the fail-safe functionality of the FDC control the pump will stroke to max. displacement in case the
input signal to the pump control and the Diesel engine will be switched off at the same time. In this
situation a low loop event can occur which may damage the pump. Therefore, it’s strictly recommended
to keep the input signal to the pump control alive while switching off the engine.
For further information please contact your Danfoss representative.

All controls are available with a Manual Over Ride (MOR) either standard or as an option for temporary
actuation of the control to aid in diagnostics.
Forward-Neutral-Reverse (FNR) and Non Feedback Proportional Electric (NFPE) controls are always
supplied with MOR functionality.
Manual OverRide (MOR)
MOR schematic diagram (EDC shown)
Unintended MOR operation will cause the pump to go into stroke. The vehicle or device must always be
in a „safe“ condition when using the MOR function. (Example: vehicle lifted off the ground)
The MOR plunger has a 4 mm diameter and must be manually depressed to be engaged. Depressing the
plunger mechanically moves the control spool which allows the pump to go on stroke. The MOR should
be engaged anticipating a full stroke response from the pump.
Warning
An o-ring seal is used to seal the MOR plunger where initial actuation of the function will require a force
of 45 N to engage the plunger. Additional actuation typically require less force to engage the MOR
plunger. Proportional control of the pump using the MOR should not be expected.
Refer to control flow table for the relationship of solenoid to direction of flow.
The angle sensor detects the swash plate position with an accuracy dependent upon the calibration
effort done for the application and direction of rotation from the neutral position. At minimum the sensor
can be used for forward, neutral and reverse (FNR) detection.
The sensor works on the hall-effect technology. The implemented technology is based on a
measurement of the magnetic field direction in parallel to the chip surface. This field direction is
converted to a voltage signal at the output.
Enhanced calibration of the non-linear behavior leads to more exact calculation of the pump swash plate
angle.
The 4-pin DEUTSCH connector is part of the sensor housing.
The swash plate angle sensor is available for all EDC controls for 12 V and 24 V.
Swash plate angle vs. output of supply voltage
Strong magnetic fields in the proximity of the sensor can influence the sensor signal and must be
avoided.

Calibration of the sensor output within the software is mandatory. Vehicle neutral thresholds in the
software (±0.5°) are vehicle dependent and must consider different conditions, example: system
temperature, system pressure and/or shaft speed.
For safety function: If the sensor fails (invalid signal <10% or >90% of supply voltage), it must be sure
that the ECU will go into a diagnostic mode and shift into limited mode in order for the driver to take the
full control or the mechanical breaks should be activated.

The H1 pump offers an optional control cut off valve integrated into the control. This valve will block
charge pressure to the control, allowing the servo springs to de-stroke both pumps regardless of the
pump´s primary control input. There is also a hydraulic logic port, X7, which can be used to control other
machine functions, such as spring applied pressure release brakes. The pressure at X7 is controlled by the
control cut off solenoid. The X7 port would remain plugged if not needed.
In the normal (de-energized) state of the solenoid charge flow is prevented from reaching the controls. At
the same time the control passages and the X7 logic port are connected and drained to the pump case.
The pump will remain in neutral, or return to neutral, independent of the control input signal. Return to
neutral time will be dependent on oil viscosity, pump speed, swashplate angle, and system pressure.
When the solenoid is energized, charge flow and pressure is allowed to reach the pump control. The X7
logic port will also be connected to charge pressure and flow.
The solenoid control is intended to be independent of the primary pump control making the control cut
off an override control feature. It is however recommended that the control logic of the CCO valve be
maintained such that the primary pump control signal is also disabled whenever the CCO valve is deenergized. Other control logic conditions may also be considered.
All EDC and MDC controls are available with a CCO valve. The CCO-valve is available with 12 V or 24 V
solenoid.
The response time of the unit depends on the control type and the used control orifices.

Displacement limiter
It is not recommended to use brake port for any external flow consumption to avoid malfunction of CCO
function.
H1 pumps are designed with optional mechanical displacement (stroke) limiters factory set to max.
displacement. The maximum displacement of the pump can be set independently for forward and
reverse using the two adjustment screws to mechanically limit the travel of the servo piston down to 50
% displacement.
Adjustments under operating conditions may cause leakage. The adjustment screw can be completely
removed from the threaded bore if backed out to far.

Mating part must maintain a minimum gap width of 1.0 mm with the shaft shoulder after installation of
the part. Transmittable torque will be reduced if the minimum gap requirement is not met.
Rated torque includes just the capability of the press-fit in accordance with an assumed fastener grade 5.
For definitions of maximum and rated torque values, refer to H1 Axial Piston Pumps Basic Information,BC00000057, the section “Shaft Torque Ratings and Spline Lubrication”.
The Danfoss H1 tapered shaft has been designed using the industry standard ISO 3019-1, minus the
through-hole in the end of the shaft. Danfoss recommends a self-locking nut instead of a castle nut and
pin. The nut and mating square-cut key are customer supplied. The specified torque rating of the tapered
shaft is based on the cross-sectional diameter of the shaft, through the keyway, and assumes the proper
clamp and fit between shaft and coupling.
Danfoss guarantees the design and manufactured quality of the tapered shaft. The customer is
responsible for the design and manufactured quality of the mating female coupling and key and applied
torque on the nut. Danfoss has made provisions for the key in accordance to the ISO specification with
the understanding that the key is solely to assist in the installation of the mating coupling.
Caution
Possible hazard because torque or loading inadvertently transmitted by the customer supplied key may
lead to premature shaft failure.
Torque must be transmitted by the taper fit between the shaft and it’s mating coupling, not the key.
