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.
Auxiliary cavity
pressure
Will be inlet pressure with internal charge pump. For reference see operating parameter on next page. Will be case pressure with
external charge supply. Please verify mating pump shaft seal capability.

Shaft loads H1P 045/053 Single
External radial shaft loads
H1 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. External radial shaft loads impact lifetime.
For lifetime calculations please contact Danfoss representative.
The maximum allowable radial 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 table and formula.
Re= Me/ L
Radial load position

Thrust loads should be avoided. Contact factory in the event thrust loads are anticipated.
Bearing life H1P 045/053
Maximum external shaft load based on shaft deflection
Unit Size 045/053
External radial moment – MeNm [lbf•in] TDB [TBD]
All external shaft loads affect bearing life. In applications with external shaft loads, minimize the impact
by positioning the load at 0° or 180° as shown in the figure.
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
swashplate is positioned on one side of center all or most of the time.

Electrical Displacement Control (EDC) options A2 (12 V)/A3 (24 V)
EDC principle
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 swashplate, changing the pump‘s displacement from full displacement in
one direction to full displacement in the opposite direction.
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.

Control response
H1 controls are available with optional control passage orifices to assist in matching the rate of
swashplate response to the application requirements (e.g. in the event of electrical failure). Software
ramp or rate limiting should be used to control vehicle response in normal operation. 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. A swashplate response table is available
for each frame indicating available swashplate response times. Testing should be conducted to verify the
proper software and orifice selection for the desired response.
H1 pumps are limited in mechanical orificing combinations. Software is envisioned as the means to
control the swashplate response in normal operating conditions. Mechanical servo orifices are to be used
only for fail-safe return to neutral in the event of an electrical failure.

Forward-Neutral-Reverse (FNR) electric control options A9 (12 V)/B1 (24 V)
The 3-Position (F-N-R) control uses an electric input signal to switch the pump to a full stroke position.
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.

Non Feedback Proportional Electric Control (NFPE) options A8 (12 V)/B8 (24 V)
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.
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 swashplate angle as system pressure increases. A typical response characteristic is shown in
the accompanying graph.
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.

Automotive Control (AC)
The H1 Automotive Control (H1 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.
